This message is handled by the Admin plugin and is responsible for all settings/channel read/write operations. This message
is used to do settings operations to both remote AND local nodes.
(Prior to 1.2 these operations were done via special ToRadio operations)
| Field | Type | Label | Description |
| ----- | ---- | ----- | ----------- |
| set_radio | [RadioConfig](#RadioConfig) | | set the radio provisioning for this node |
| set_owner | [User](#User) | | Set the owner for this node |
| set_channel | [Channel](#Channel) | | Set channels (using the new API). A special channel is the "primary channel". The other records are secondary channels. Note: only one channel can be marked as primary. If the client sets a particular channel to be primary, the previous channel will be set to SECONDARY automatically |
| get_channel_request | [uint32](#uint32) | | Send the specified channel in the response for this message NOTE: This field is sent with the channel index + 1 (to ensure we never try to send 'zero' - which protobufs treats as not present) |
| confirm_set_channel | [bool](#bool) | | Setting channels/radio config remotely carries the risk that you might send an invalid config and the radio never talks to your mesh again. Therefore if setting either of these properties remotely, you must send a confirm_xxx message within 10 minutes. If you fail to do so, the radio will assume loss of comms and revert your changes. These messages are optional when changing the local node. |
any SECONDARY channels. No DISABLED channels are included.
This abstraction is used only on the the 'app side' of the world (ie python, javascript and android etc) to show a group of Channels as a (long) URL
| gateway_id | [string](#string) | | The sending gateway. Can we use this to authenticate/prevent fake nodeid impersonation for senders? - i.e. use gateway/mesh id (which is authenticated) + local node id as the globally trusted nodenum |
| index | [int32](#int32) | | The index of this channel in the channel table (from 0 to MAX_NUM_CHANNELS-1) (Someday - not currently implemented) An index of -1 could be used to mean "set by name", in which case the target node will find and set the channel by settings.name. |
| tx_power | [int32](#int32) | | If zero then, use default max legal continuous power (ie. something that won't burn out the radio hardware) In most cases you should use zero here. Units are in dBm. |
| modem_config | [ChannelSettings.ModemConfig](#ChannelSettings.ModemConfig) | | Note: This is the 'old' mechanism for specifying channel parameters. Either modem_config or bandwidth/spreading/coding will be specified - NOT BOTH. As a heuristic: If bandwidth is specified, do not use modem_config. Because protobufs take ZERO space when the value is zero this works out nicely. This value is replaced by bandwidth/spread_factor/coding_rate. If you'd like to experiment with other options add them to MeshRadio.cpp in the device code. |
| bandwidth | [uint32](#uint32) | | Bandwidth in MHz Certain bandwidth numbers are 'special' and will be converted to the appropriate floating point value: 31 -> 31.25MHz |
| spread_factor | [uint32](#uint32) | | A number from 7 to 12. Indicates number of chirps per symbol as 1<<spread_factor. |
| coding_rate | [uint32](#uint32) | | The denominator of the coding rate. ie for 4/8, the value is 8. 5/8 the value is 5. |
| channel_num | [uint32](#uint32) | | A channel number between 1 and 13 (or whatever the max is in the current region). If ZERO then the rule is "use the old channel name hash based algorithm to derive the channel number") If using the hash algorithm the channel number will be: hash(channel_name) % NUM_CHANNELS (Where num channels depends on the regulatory region). NUM_CHANNELS_US is 13, for other values see MeshRadio.h in the device code. hash a string into an integer - djb2 by Dan Bernstein. - http://www.cse.yorku.ca/~oz/hash.html unsigned long hash(char *str) { unsigned long hash = 5381; int c; while ((c = *str++) != 0) hash = ((hash << 5) + hash) + (unsigned char) c; return hash; } |
| psk | [bytes](#bytes) | | A simple pre-shared key for now for crypto. Must be either 0 bytes (no crypto), 16 bytes (AES128), or 32 bytes (AES256) A special shorthand is used for 1 byte long psks. These psks should be treated as only minimally secure, because they are listed in this source code. Those bytes are mapped using the following scheme: `0` = No crypto `1` = The special default channel key: {0xd4, 0xf1, 0xbb, 0x3a, 0x20, 0x29, 0x07, 0x59, 0xf0, 0xbc, 0xff, 0xab, 0xcf, 0x4e, 0x69, 0xbf} `2` through 10 = The default channel key, except with 1 through 9 added to the last byte |
| name | [string](#string) | | A SHORT name that will be packed into the URL. Less than 12 bytes. Something for end users to call the channel If this is the empty string it is assumed that this channel is the special (minimally secure) "Default"channel. In user interfaces it should be rendered as a local language translation of "X". For channel_num hashing empty string will be treated as "X". Where "X" is selected based on the English words listed above for ModemConfig |
| id | [fixed32](#fixed32) | | Used to construct a globally unique channel ID. The full globally unique ID will be: "name.id" where ID is shown as base36. Assuming that the number of meshtastic users is below 20K (true for a long time) the chance of this 64 bit random number colliding with anyone else is super low. And the penalty for collision is low as well, it just means that anyone trying to decrypt channel messages might need to try multiple candidate channels. Any time a non wire compatible change is made to a channel, this field should be regenerated. There are a small number of 'special' globally known (and fairly) insecure standard channels. Those channels do not have a numeric id included in the settings, but instead it is pulled from a table of well known IDs. (see Well Known Channels FIXME) |
| uplink_enabled | [bool](#bool) | | If true, messages on the mesh will be sent to the *public* internet by any gateway ndoe |
| downlink_enabled | [bool](#bool) | | If true, messages seen on the internet will be forwarded to the local mesh. |
<aname=".Channel.Role"></a>
### Channel.Role
How this channel is being used (or not).
Note: this field is an enum to give us options for the future. In particular, someday
we might make a 'SCANNING' option. SCANNING channels could have different frequencies and the radio would
occasionally check that freq to see if anything is being transmitted.
For devices that have multiple physical radios attached, we could keep multiple PRIMARY/SCANNING channels active at once to allow
cross band routing as needed. If a device has only a single radio (the common case) only one channel can be PRIMARY at a time
(but any number of SECONDARY channels can't be sent received on that common frequency)
| Name | Number | Description |
| ---- | ------ | ----------- |
| DISABLED | 0 | This channel is not in use right now |
| PRIMARY | 1 | This channel is used to set the frequency for the radio - all other enabled channels must be SECONDARY |
| SECONDARY | 2 | Secondary channels are only used for encryption/decryption/authentication purposes. Their radio settings (freq etc) are ignored, only psk is used. |
<aname=".ChannelSettings.ModemConfig"></a>
### ChannelSettings.ModemConfig
Standard predefined channel settings
Note: these mappings must match ModemConfigChoice in the device code.
| Name | Number | Description |
| ---- | ------ | ----------- |
| Bw125Cr45Sf128 | 0 | < Bw = 125 kHz, Cr = 4/5, Sf(7) = 128chips/symbol, CRC < on. Default medium range (5.469 kbps) |
This message is never sent over the wire, but it is used for serializing DB
state to flash in the device code
FIXME, since we write this each time we enter deep sleep (and have infinite
flash) it would be better to use some sort of append only data structure for
the receive queue and use the preferences store for the other stuff
| Field | Type | Label | Description |
| ----- | ---- | ----- | ----------- |
| my_node | [MyNodeInfo](#MyNodeInfo) | | Read only settings/info about this node |
| owner | [User](#User) | | My owner info |
| node_db | [NodeInfo](#NodeInfo) | repeated | |
| receive_queue | [MeshPacket](#MeshPacket) | repeated | Received packets saved for delivery to the phone |
| version | [uint32](#uint32) | | A version integer used to invalidate old save files when we make incompatible changes This integer is set at build time and is private to NodeDB.cpp in the device code. |
| rx_text_message | [MeshPacket](#MeshPacket) | | We keep the last received text message (only) stored in the device flash, so we can show it on the screen. Might be null |
| no_save | [bool](#bool) | | Used only during development. Indicates developer is testing and changes should never be saved to flash. |
| want_response | [bool](#bool) | | Not normally used, but for testing a sender can request that recipient responds in kind (i.e. if it received a position, it should unicast back it's position). Note: that if you set this on a broadcast you will receive many replies. |
| dest | [fixed32](#fixed32) | | The address of the destination node. This field is is filled in by the mesh radio device software, application layer software should never need it. RouteDiscovery messages _must_ populate this. Other message types might need to if they are doing multihop routing. |
| source | [fixed32](#fixed32) | | The address of the original sender for this message. This field should _only_ be populated for reliable multihop packets (to keep packets small). |
| request_id | [fixed32](#fixed32) | | Only used in routing or response messages. Indicates the original message ID that this message is reporting failure on. (formerly called original_id) |
| my_info | [MyNodeInfo](#MyNodeInfo) | | Tells the phone what our node number is, can be -1 if we've not yet joined a mesh. NOTE: This ID must not change - to keep (minimal) compatibility with <1.2 version of android apps. |
| config_complete_id | [uint32](#uint32) | | sent as true once the device has finished sending all of the responses to want_config recipient should check if this ID matches our original request nonce, if not, it means your config responses haven't started yet. NOTE: This ID must not change - to keep (minimal) compatibility with <1.2 version of android apps. |
| rebooted | [bool](#bool) | | Sent to tell clients the radio has just rebooted. Set to true if present. Not used on all transports, currently just used for the serial console. NOTE: This ID must not change - to keep (minimal) compatibility with <1.2 version of android apps. |
| from | [fixed32](#fixed32) | | The sending node number. Note: Our crypto implementation uses this field as well. See docs/software/crypto.md for details. FIXME - really should be fixed32 instead, this encoding only hurts the ble link though. |
| to | [fixed32](#fixed32) | | The (immediatSee Priority description for more details.y should be fixed32 instead, this encoding only hurts the ble link though. |
| channel | [uint32](#uint32) | | (Usually) If set, this indicates the index in the secondary_channels table that this packet was sent/received on. If unset, packet was on the primary channel. A particular node might know only a subset of channels in use on the mesh. Therefore channel_index is inherently a local concept and meaningless to send between nodes. Very briefly, while sending and receiving deep inside the device Router code, this field instead contains the 'channel hash' instead of the index. This 'trick' is only used while the payloadVariant is an 'encrypted'. |
| id | [fixed32](#fixed32) | | A unique ID for this packet. Always 0 for no-ack packets or non broadcast packets (and therefore take zero bytes of space). Otherwise a unique ID for this packet, useful for flooding algorithms. ID only needs to be unique on a _per sender_ basis, and it only needs to be unique for a few minutes (long enough to last for the length of any ACK or the completion of a mesh broadcast flood). Note: Our crypto implementation uses this id as well. See docs/software/crypto.md for details. FIXME - really should be fixed32 instead, this encoding only hurts the ble link though. |
| rx_time | [fixed32](#fixed32) | | The time this message was received by the esp32 (secs since 1970). Note: this field is _never_ sent on the radio link itself (to save space) Times are typically not sent over the mesh, but they will be added to any Packet (chain of SubPacket) sent to the phone (so the phone can know exact time of reception) |
| rx_snr | [float](#float) | | Never* sent over the radio links. Set during reception to indicate the SNR of this packet. Used to collect statistics on current link quality. |
| hop_limit | [uint32](#uint32) | | If unset treated as zero (no forwarding, send to adjacent nodes only) if 1, allow hopping through one node, etc... For our usecase real world topologies probably have a max of about 3. This field is normally placed into a few of bits in the header. |
| want_ack | [bool](#bool) | | This packet is being sent as a reliable message, we would prefer it to arrive at the destination. We would like to receive a ack packet in response. Broadcasts messages treat this flag specially: Since acks for broadcasts would rapidly flood the channel, the normal ack behavior is suppressed. Instead, the original sender listens to see if at least one node is rebroadcasting this packet (because naive flooding algorithm). If it hears that the odds (given typical LoRa topologies) the odds are very high that every node should eventually receive the message. So FloodingRouter.cpp generates an implicit ack which is delivered to the original sender. If after some time we don't hear anyone rebroadcast our packet, we will timeout and retransmit, using the regular resend logic. Note: This flag is normally sent in a flag bit in the header when sent over the wire |
| priority | [MeshPacket.Priority](#MeshPacket.Priority) | | The priority of this message for sending. See MeshPacket.Priority description for more details. |
| my_node_num | [uint32](#uint32) | | Tells the phone what our node number is, default starting value is lowbyte of macaddr, but it will be fixed if that is already in use |
| has_gps | [bool](#bool) | | Note: this bool no longer means "we have our own GPS". Because gps_operation is more advanced, but we'd like old phone apps to keep working. So for legacy reasons we set this flag as follows: if false it would be great if the phone can help provide gps coordinates. If true we don't need location assistance from the phone. |
| num_bands | [uint32](#uint32) | | # of frequencies that can be used (set at build time in the device flash image). Note: this is different from max_channels, this field is telling the # of frequency bands this node can use. (old name was num_channels) |
| max_channels | [uint32](#uint32) | | The maximum number of 'software' channels that can be set on this node. |
| region | [string](#string) | | **Deprecated.** Deprecated! ONLY USED IN DEVICE CODE (for upgrading old 1.0 firmwares) DO NOT READ ELSEWHERE. The region code for my radio (US, CN, etc...) Note: This string is deprecated. The 1.0 builds populate it based on the flashed firmware name. But for newer builds this string will be unpopulated (missing/null). For those builds you should instead look at the new read/write region enum in UserSettings The format of this string was 1.0-US or 1.0-CN etc.. Or empty string if unset. |
| error_code | [CriticalErrorCode](#CriticalErrorCode) | | An error message we'd like to report back to the mothership through analytics. It indicates a serious bug occurred on the device, the device coped with it, but we still want to tell the devs about the bug. This field will be cleared after the phone reads MyNodeInfo (i.e. it will only be reported once) a numeric error code to go with error message, zero means no error |
| error_count | [uint32](#uint32) | | The total number of errors this node has ever encountered (well - since the last time we discarded preferences) |
| message_timeout_msec | [uint32](#uint32) | | How long before we consider a message abandoned and we can clear our caches of any messages in flight Normally quite large to handle the worst case message delivery time, 5 minutes. Formerly called FLOOD_EXPIRE_TIME in the device code |
| min_app_version | [uint32](#uint32) | | The minimum app version that can talk to this device. Phone/PC apps should compare this to their build number and if too low tell the user they must update their app |
| snr | [float](#float) | | Returns the Signal-to-noise ratio (SNR) of the last received message, as measured by the receiver. Return SNR of the last received message in dB |
| next_hop | [uint32](#uint32) | | Returns the last measured frequency error. The LoRa receiver estimates the frequency offset between the receiver center frequency and that of the received LoRa signal. This function returns the estimates offset (in Hz) of the last received message. Caution: this measurement is not absolute, but is measured relative to the local receiver's oscillator. Apparent errors may be due to the transmitter, the receiver or both. \return The estimated center frequency offset in Hz of the last received message. int32 frequency_error = 6; enum RouteState { Invalid = 0; Discovering = 1; Valid = 2; } Not needed? RouteState route = 4; Our current preferred node node for routing - might be the same as num if we are adjacent Or zero if we don't yet know a route to this node. |
| time | [fixed32](#fixed32) | | This is usually not sent over the mesh (to save space), but it is sent from the phone so that the local device can set its RTC If it is sent over the mesh (because there are devices on the mesh without GPS), it will only be sent by devices which has a hardware GPS clock. seconds since 1970 |
| route_request | [RouteDiscovery](#RouteDiscovery) | | A route request going from the requester |
| route_reply | [RouteDiscovery](#RouteDiscovery) | | A route reply |
| error_reason | [Routing.Error](#Routing.Error) | | A failure in delivering a message (usually used for routing control messages, but might be provided in addition to ack.fail_id to provide details on the type of failure). |
| packet | [MeshPacket](#MeshPacket) | | send this packet on the mesh |
| want_config_id | [uint32](#uint32) | | phone wants radio to send full node db to the phone, This is typically the first packet sent to the radio when the phone gets a bluetooth connection. The radio will respond by sending back a MyNodeInfo, a owner, a radio config and a series of FromRadio.node_infos, and config_complete the integer you write into this field will be reported back in the config_complete_id response this allows clients to never be confused by a stale old partially sent config. |
<aname=".User"></a>
### User
Broadcast when a newly powered mesh node wants to find a node num it can use
| id | [string](#string) | | A globally unique ID string for this user. In the case of Signal that would mean +16504442323, for the default macaddr derived id it would be !<8 hexidecimal bytes> Note: app developers are encouraged to also use the following standard node IDs "^all" (for broadcast), "^local" (for the locally connected node) |
| DATA_PAYLOAD_LEN | 240 | From mesh.options note: this payload length is ONLY the bytes that are sent inside of the radiohead packet Data.payload max_size:240 |
This change is backwards compatible by treating the legacy OPAQUE/CLEAR_TEXT values identically.
| Name | Number | Description |
| ---- | ------ | ----------- |
| UNKNOWN_APP | 0 | Deprecated: do not use in new code (formerly called OPAQUE) A message sent from a device outside of the mesh, in a form the mesh does not understand NOTE: This must be 0, because it is documented in IMeshService.aidl to be so |
| TEXT_MESSAGE_APP | 1 | A simple UTF-8 text message, which even the little micros in the mesh can understand and show on their screen eventually in some circumstances even signal might send messages in this form (see below) Formerly called CLEAR_TEXT |
| REMOTE_HARDWARE_APP | 2 | A message receive acknowledgment, sent in cleartext - allows radio to show user that a message has been read by the recipient, optional Note: this concept has been removed for now. Once READACK is implemented, use the new packet type/port number stuff? @exclude CLEAR_READACK = 2; Reserved for built-in GPIO/example app. See remote_hardware.proto/HardwareMessage for details on the message sent/received to this port number |
| POSITION_APP | 3 | The built-in position messaging app. See Position for details on the message sent to this port number. payload is a Position protobuf |
| NODEINFO_APP | 4 | The built-in user info app. See User for details on the message sent to this port number. payload is a User protobuf |
| ROUTING_APP | 5 | Protocol control packets for mesh protocol use, payload is a Routing protobuf |
| SERIAL_APP | 64 | Provides a hardware serial interface to send and receive from the Meshtastic network. Connect to the RX/TX pins of a device with 38400 8N1. Packets received from the Meshtastic network is forwarded to the RX pin while sending a packet to TX will go out to the Mesh network. Maximum packet size of 240 bytes. Plugin is disabled by default can be turned on by setting SERIALPLUGIN_ENABLED = 1 in SerialPlugh.cpp. Maintained by Jm Casler (MC Hamster) : jm@casler.org |
| STORE_FORWARD_APP | 65 | STORE_FORWARD_APP (Work in Progress) Maintained by Jm Casler (MC Hamster) : jm@casler.org |
| RANGE_TEST_APP | 66 | STORE_FORWARD_APP (Work in Progress) Maintained by Jm Casler (MC Hamster) : jm@casler.org |
| ENVIRONMENTAL_MEASUREMENT_APP | 67 | Provides a format to send and receive environmental data from the Meshtastic network. Maintained by Charles Crossan (crossan007) : crossan007@gmail.com |
| PRIVATE_APP | 256 | Private applications should use portnums >= 256. To simplify initial development and testing you can use "PRIVATE_APP" in your code without needing to rebuild protobuf files (via bin/regin_protos.sh) |

| Field | Type | Label | Description |
| ----- | ---- | ----- | ----------- |

| region | [RegionCode](#RegionCode) | | The region code for my radio (US, CN, EU433, etc...) |
| charge_current | [ChargeCurrent](#ChargeCurrent) | | Sets the current of the battery charger |
| is_router | [bool](#bool) | | Are we operating as a router. Changes behavior in the following ways: The device will only sleep for critically low battery level (i.e. always tries to stay alive for the mesh) In the future routing decisions will preferentially route packets through nodes with this attribute (because assumed good line of sight) |
| is_low_power | [bool](#bool) | | If set, we are powered from a low-current source (i.e. solar), so even if it looks like we have power flowing in we should try to minimize power consumption as much as possible. YOU DO NOT NEED TO SET THIS IF YOU'VE set is_router (it is implied in that case). |
| fixed_position | [bool](#bool) | | If set, this node is at a fixed position. We will generate GPS position updates at the regular interval, but use whatever the last lat/lon/alt we have for the node. The lat/lon/alt can be set by an internal GPS or with the help of the app. |
| factory_reset | [bool](#bool) | | This setting is never saved to disk, but if set, all device settings will be returned to factory defaults. (Region, serial number etc... will be preserved) |
| debug_log_enabled | [bool](#bool) | | By default we turn off logging as soon as an API client connects (to keep shared serial link quiet). Set this to true to leave the debug log outputting even when API is active. |
| location_share | [LocationSharing](#LocationSharing) | | How our location is shared with other nodes (or the local phone) |
| gps_operation | [GpsOperation](#GpsOperation) | | How the GPS hardware in this unit is operated. Note: This is independent of how our location is shared with other devices. For that see LocationSharing |
| gps_update_interval | [uint32](#uint32) | | How often should we try to get GPS position (in seconds) when we are in GpsOpMobile mode? or zero for the default of once every 30 seconds or a very large value (maxint) to update only once at boot. |
| gps_attempt_time | [uint32](#uint32) | | How long should we try to get our position during each gps_update_interval attempt? (in seconds) Or if zero, use the default of 30 seconds. If we don't get a new gps fix in that time, the gps will be put into sleep until the next gps_update_rate window. |
| ignore_incoming | [uint32](#uint32) | repeated | If true, radio should not try to be smart about what packets to queue to the phone bool keep_all_packets = 101; If true, we will try to capture all the packets sent on the mesh, not just the ones destined to our node. bool promiscuous_mode = 102; For testing it is useful sometimes to force a node to never listen to particular other nodes (simulating radio out of range). All nodenums listed in ignore_incoming will have packets they send droped on receive (by router.cpp) |
| serialplugin_enabled | [bool](#bool) | | Preferences for the SerialPlugin FIXME - Move this out of UserPreferences and into a section for plugin configuration. |
| ext_notification_plugin_enabled | [bool](#bool) | | Preferences for the ExternalNotificationPlugin FIXME - Move this out of UserPreferences and into a section for plugin configuration. |
| range_test_plugin_enabled | [bool](#bool) | | Preferences for the RangeTestPlugin FIXME - Move this out of UserPreferences and into a section for plugin configuration. |
| store_forward_plugin_enabled | [bool](#bool) | | Preferences for the StoreForwardPlugin FIXME - Move this out of UserPreferences and into a section for plugin configuration. |

| environmental_measurement_plugin_read_error_count_threshold | [uint32](#uint32) | | Sometimes sensor reads can fail. If this happens, we will retry a configurable number of attempts Each attempt will be delayed by the minimum required refresh rate for that sensor |
| environmental_measurement_plugin_update_interval | [uint32](#uint32) | | Interval in seconds of how often we should try to send our measurements to the mesh |
| environmental_measurement_plugin_recovery_interval | [uint32](#uint32) | | Sometimes we can end up with more than read_error_count_threshold failures. In this case, we will stop trying to read from the sensor for a while. Wait this long until trying to read from the sensor again |
| environmental_measurement_plugin_display_farenheit | [bool](#bool) | | We'll always read the sensor in Celsius, but sometimes we might want to display the results in Farenheit as a "user preference". |
| GpsOpStationary | 1 | Note: This mode was removed, because it is identical go GpsOpMobile with a gps_update_rate of once per day This node is mostly stationary, we should try to get location only once per day, Once we have that position we should turn the GPS to sleep mode This is the recommended configuration for stationary 'router' nodes |
| GpsOpMobile | 2 | This node is mobile and we should get GPS position at a rate governed by gps_update_rate |
| GpsOpTimeOnly | 3 | We should only use the GPS to get time (no location data should be acquired/stored) Once we have the time we treat gps_update_interval as MAXINT (i.e. sleep forever) |
| GpsOpDisabled | 4 | GPS is always turned off - this mode is not recommended - use GpsOpTimeOnly instead |
<aname=".LocationSharing"></a>
### LocationSharing
How our location is shared with other nodes (or the local phone)
| Name | Number | Description |
| ---- | ------ | ----------- |
| LocUnset | 0 | This is the default and treated as LocEnabled) |
| LocEnabled | 1 | We are sharing our location |
| LocDisabled | 2 | We are not sharing our location (if the unit has a GPS it will default to only get time - i.e. GpsOpTimeOnly) |
| gpio_mask | [uint64](#uint64) | | What gpios are we changing. Not used for all MessageTypes, see MessageType for details |
| gpio_value | [uint64](#uint64) | | For gpios that were listed in gpio_mask as valid, what are the signal levels for those gpios. Not used for all MessageTypes, see MessageType for details |
| WATCH_GPIOS | 2 | We are now interested in watching the gpio_mask gpios. If the selected gpios change, please broadcast GPIOS_CHANGED. Will implicitly change the gpios requested to be INPUT gpios. |
| <aname="int32"/> int32 | Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint32 instead. | int32 | int | int | int32 | int | integer | Bignum or Fixnum (as required) |
| <aname="int64"/> int64 | Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint64 instead. | int64 | long | int/long | int64 | long | integer/string | Bignum |
| <aname="sint32"/> sint32 | Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s. | int32 | int | int | int32 | int | integer | Bignum or Fixnum (as required) |
