- Support for T-BEAM V1.2 (axp1201 power chip),
T-BEAM V1.1 and V.0 used the axp192.
Unfortunately, this new chip is not able to read current load.
In the case of telemetry, we do not drop the current readings (but set it
to 0). This notation may change in future.
- Feature for needed in SP:
enable TX on main and secondary frequency as user.
Signed-off-by: Thomas Osterried <dl9sau@darc.de>
- platform.ini: changed env:xxx-1.0 to xxx-1_0, because latest
platformio complains about the dot.
- Optional: send beacon as object
This is recommended if you like an aps icon like L, while using
your normal ssid like DL9SAU-12
You can set it in the webinterface, of by compile time in platform.ini
- if you really insist in adding SSID -L4 to your callsign,
your RF TX will be disabled. You can connect with that call to to aprs-is.
- renamed function name compute_locator() to locator_to_lat_lon(),
because it's more clear
- GPS accuracy:
GPS becomes inaccurate if you move very slow or halt.
These jumps may have a distance of more than 100m.
If we take hdop and visible satellites into acount, the situation
improves significant.
A measured height needs even more sats and better vdop.
Beacons are also triggered by course change. Speed is not a good
indicator, because speed is computed by location change. And if
you jump 200m in between 5s, then you speed is interpreted as 144km/h.
This leads to wrong assumptions about course change.
As far as we know, our changes have no impact to the quality of the
positions and the course change detection for smart-beaconing.
hdop and sat values for exacter location, course, speed,
and altitude have been testet by experiment. If you like, you
may find better values.
After this commit, we'll test extensively. Then it will become
a release dedicated to HAMRADIO 2023 ;)

Improvements
- Even more intelligent behavior in "Allow failback Mode AP"
- Webserver: Current GPS location can be stored as current lat/lon;
And fixed a not-so-nice down-rounding from i.e.
53.2100N to 53.2099N
- Webserver: better input handling for ap password, remoteAP ssid and
password, syslog and ntp server
- Webserver: fixed typos in tooltip texts, and improved documentation,
especially for the new features
- Position ambiguity and higher precision
You can choose now between
- compressed position (also when fixed position).
- uncompressed aprs position
- uncompressed aprs position with higher precision (DAO W and w)
Improvement for unknown position: encode it according to aprs spec
- OLED: more variants to display lat/lon positions.
Displayed lat/lon resolution depends on setting and if you move,
and current gps hdop.
You can also configure if maidenhead grid locator is shown (always,
never, in intervals). Locator could be shown as RR99XX, RR99XX99
or RR99XX99xx - you can choose which variant you like.
- Oled Lines: one-liners now cut at end of display-length;
except for line2 (if line3-5 are empty).
Oled display.display() is called only if display is on.
Improvement for fillDisplayLines3to5 (may be forced)
- Serial output on boot: Warn for unser preference variables only once,
and set them accordingly
- Digipeating / Gate handling. Don't send 3rd-party packets
back to aprsis. Digipeat telemetry only do secondary qrg.
- aprs-is:
- 3rd-party traffic: it's not seldom that igates use
lowercase calls. Don't tread this as (minor) error anymore.
- aprs-is: improved filters according to aprsis spec
- digipeating:
- if we are a WIDE1 (= fill-in) digi and if a packet is in
lora_TXBUF_for_digipeating and we hear a repeated one with same
source-address and content, we clear it from queue.
Improved viscous-delay.
For development (compile time): different debug-verbose levels
Fixes
- aprsLatPreset (etc..) variables are now changed from their temporary
variable names at once. Reading from preferences, a separate
variable is filled. This mitigates a smp problem between webserver
and main threads
- aprsis login messages missed word "vers " placed before the version string
- Small fix for aprsis 3rd party traffic encoding according to the spec.
- Some numbers with decimals are now shown complete (instead of cut'ed
to two decimals (default of String(floatVariable)).
- fixes for some buffer dimensions; detected two buffer overflow conditions
- Telemetry: assurance that values > 255 are ceiled and not start from 0 again
(An analoge value must not exceet 255)

in Engen 2023-02-11 ;)

- new web option
- Otion Send Course/Speed along with Altitude.
Removed option "Show Altitude in compressed position" removed.
- Added hint for min/max values in tooltip
- Tips for reducing power
- platformio.ini:
- enabled ENABLE_TNC_SELF_TELEMETRY.
Reason: imho, no really need for telemetry. But code is not much.
Tried to configure it in web-iface for debug purpose and it had no effect:
because it was not compiled in.
- always_send_cseSpd_AND_altitude feature (see also webconfig)
- sendpacket() now gets information (flags) why / for what it is called
This is for deciding if you send altitude with each transmission
(then course/speed is always sent in compressed format, and /A=......
is added to the message text). [Vice versa is not allowed due to spec]
If disabled, one transmission has course/speed and the next one
altitude (depending on altitude ratio). Pretty cewl ;)
- improvements on display output
- improvements for handling gps state change valid/invalid.
Lesser (better) cpu-consuming storage of last position.
It's now handled in one routine at start of the main loop.
- mheard list: json list was cuted.
-> - DynamicJsonDocument doc(MAX_RECEIVED_LIST_SIZE * 500);
+ DynamicJsonDocument doc(MAX_RECEIVED_LIST_SIZE * 1000);
But we still face the problem of empty mheard lists in the webinterface.
-> STILL NEED FOR FIX
- webserver
- wifi client / AP:
Fix. If you loose connection to the AP, we now go to the
algorithm again for reconnect, or start own AP. And if no client
is associated in AP mode, we also try to re-determine.
-> moved to new function restart_AP_or_STA()
Reconnect also if we are STA and got no IP address by dhcp
(there are some known compatibility issues with some dhcp-serrvers,
where on dhcp refresh we lost the gateway):
if (WiFi.getMode() == 1 && (WiFi.status() != WL_CONNECTED || WiFi.localIP() == IP_NULL || WiFi.subnetMask() == IP_SUBNET_NULL || WiFi.gatewayIP() == IP_GATEWAY_NULL))
- wifi status now with one status variable, i.E.:
wifi_connection_status = WIFI_RUNNING_AS_AP;
Used in the main program for display routine.

And finally, from the old changelog with changes since the last release:
Changelog of 2022-08-09:
Fix
- logical error for setting lora chip to sleep after tx;
affected users with digipeating mode switched off. -> They did not receive
any RF packets.
Improvements:
- hack for re-enabling webserver if it was switched off_
moved from the short-pressed beacon button to the long-pressed GPS button.
Thanks to Thomas Beiderwieden <dl3el> for the patch.
Feature
- If you press the GPS button, on your OLED display now your AP name and
IP address are displayed.
Thanks to Thomas Beiderwieden <dl3el> for the patch.
- Known issues
The first Menu in the webinterface, "Enable WIFI", stores the chosen
value. You can see it in the json config, and how boot-up behaves
(-> correctly stored in the preferences).
But: the chooser always displays Menu item 1 as active.

Changelog of 2022-08-07:
Major improvements and smaller bugfixes
- feature: option to disable wifi. Saves abt 80mA current
3 options: 2 alaways on; 1 off if no bluetooth client is connected in between
60s after boot (watch red oled button; goes off as soon as a
bt client connects in the boot phase). 0 disable (re-enabl by pressing
beacon button)
- pseudo csma/cd. ppersist / slottime as we know it from standard
packet-radio / -APRS
In loaSend. TODO: better concept with a tx-queue. But this is rather complex,
because the queue must not grow too large, else we re-send old packts..
- feature to encode altitude in compressed position instead of /A=...
compressed position can encode course/speed, altitude (and others). Option to
send course/speed to 0%, 100% or something in between.
altitude check button is obsolete. Switch off by setting alt ratio to 0.
- cross-digipeating: just for sure, clear rx queue after going back to main
freq.
- if we are not a digipeater and we have no serial-bt-client, we may let the
loraChip sleep (axp.setPowerOutPut(AXP192_LDO2, AXP202_OFF)) -> saves current
(a bit)
- adjust_cpu_freq_to: change CPU frequency. May reduce cpu power consumption
up to 20 %. Suggesting (and tested with) 80 MHz. USE WITH CARE! I.e.
40 MHz or 20 MHz did not work with my device (boot phase never ended)
- options to start tncServer and gpsServer (if you don't need them, you
may not like to expose these tcp ports to your LAN or HAMNET)
- changed preferences.getString(PREFxxxxx) to
preferences.getString(PREFxxxxx, ""), because if variable is not set,
the preferences library returns "the variable name itself" - wtf!.
In the case of PREF_NTP_SERVER, we saw log messages that ntp server
with fqdn "ntp_server" could not be resolved; it had no impact, because
it did a failback to the compiled-in default. Changed call for
PREF_WIFI_PASSWORD, PREF_AP_PASSWORD, etc.. too.
- wifi-AP: is set to esp_wifi_set_max_tx_power(8) (for lesser power
consumption of the devie). 8 dBm are too less fore some cases.
-> New web config for setting max_tx_power in AP- and STA- modes.
- Fix: In mode wifi-client, it did not reconnect if association was lost.
- small improvement for comment-text ratelimiting
BG_RF95.cpp: BG_RF95::SignalDetected feature (needed for pseudo csma/cd)

TTGO LoRa32 V2.1 (aka T3 V1.6.1) has a bug if you use wifi and bt at the

the web server is started-

tested).

Major upgrade
- SNR/RSSI encoding (Q...) feature:
- changed default preference for SNR/RSSI encoding (Q...) to
lora_add_snr_rssi_to_path = (FLAG_ADD_SNR_RSSI_FOR_KISS |
_FLAG_ADD_SNR_RSSI_FOR_APRSIS__ONLY_IF_HEARD_DIRECT)
..HEARD_DIRECT is a new feature
- user may request SNR/RSSI trace by adding to path 'Q' (digis who hear
him direct add SNR/RSSI), or 'QQ' (every digi adds - useful for
local RF network trace)
- more config options in Web-Interface
- Relay-Path: check for invalid input. More tips how to configure.
Auto-suggest "WIDE1-1" if unexperienced user enters "WIDE1"
- Fixed location setting of Latitude / Longitude:
Previously, a user had to know the correct notation of APRS spec.
Now, we are pretty smart and can handle different notations,
inclusive MAIDENHEAD GRID ;)
- blacklist filter for src-calls and calls in digi path
- if you have a digipeater or user which behaves bad
- against mis-use of our infrastructure
- config option for switching of lora RX
- MY_APRS_DEST_IDENTIFYER = ... as one global string instead of multible
occourences in the code
- improved packet validation
- web-interface input validation (trim() to strip leading/trailing spaces),
i.e. att callsign, relay path, aprs-is-server-name, -call and -password, ..
- third-partytraffic: changed dstcall from "APRS" to MY_APRS_DEST_IDENTIFYER
..and a test to circumvent github firmware download bug that came in end 2021

New features:
- txpower configurable (previously only compile time option in platform.ini)
If not configured in platform.ini (previously necessary), it now defaults to 23.0
- New Enable LoRa TX variable. If disabled, it's assured that TX will never happen
(i.e. in order to protect rx amplifier)
This option is also definable in platformio.ini, if you comment out:
;-D 'TXDISABLE'
If set, it also enforces txpower 0.
=>
#ifdef TXDISABLE // define TXDISABLE if you like to ensure that we never
TX (i.e. if we are behind an rx-amplifier)
boolean lora_tx_enabled = false;
uint8_t txPower = 0;
#else
boolean lora_tx_enabled = true;
#ifdef TXdbmW
uint8_t txPower = TXdbmW;
#else
uint8_t txPower = 23;
#endif
endif
;))
- Web-Interface: Link to /cfg (-> make it easier for users to show the json and
store the current configuration). This is better than making screenshots of
the website ;)
If could be done better (download link, ..). And possibility to upload
the configuration from backup. Who likes to implement this?

CAVE:
webconfig does not work properly. This needs to be fixed before the changes could go upstream!
Until then, you can hardcode values in TTGO_T-Beam_LoRa_APRS.ino after the
"// enforce valid transmissions even on wrong configurations"
section.
For examples, see appendix 1.
New features
Changes
- improved automatic CodeRate adaption
- Concept for adding SNR+RSSI in packet path. Q23073* means, 23 dB SNR, -73 dB RSSI.
- full smart-beaconing implementation, with default parameters from kenwood / yaesu devices
Changed files:
1. data_embed/index.html
------------------------
- cosmetic changes
- added configuration options for new features described above
- description how to configure DST-call-path-addressing
- make configurable
- automatic coderate adaption
- rate limiting comment text
- My recent "Accept own positions via KISS" feature
- My recent "Allow GPS sleep while own positions received via KISS" feature
- LoRa Digipeating
- LoRa cross-digipeating (Mode, frequency, speed)
2. preference_storage.h
-----------------------
definitions for the new configuration variables
3. platformio.ini
------------------k
Variable MAX_TIME_TO_NEXT_TXT commented out. Was not implemented, and needs not be configured anymore.
Default enabling of
ENABLE_TNC_SELF_TELEMETRY
switched off because most people do not need this
DIGI_PATH="1": suggestion to make this default
"FIXED_BEACON_EN": switched off, because if you have a tracker with GPS, you do smart-beaconing.
Or if you have no GPS, you need to configure LAT/LONG before enabling fixed beaconing.
"SHOW_BATT": if you really need this, enable it.
"SPEED_1200": most regions use 300.
Typo:
LATIDUDE_PRESET -> changed to LATITUDE_PRESET (also in TTGO_T-Beam_LoRa_APRS.ino)
4. TTGO_T-Beam_LoRa_APRS.ino
----------------------------
global variables:
- -D SPEED_1200 had not effekt. Added appropriete #ifdef.
Perhaps, "LORA_SPEED_LOW" or "LORA_SPEED_FAST" (like mentioned in the web interface) would be a better approach
- gps state: set default on only at devices with GPS-RX
- New smartbeaconing:
- values like sb_turn_slope and sb_turn_time
- if -D SB_ALGO_KENWOOD, use those defaults. Scales better at low speed.
- my new featerus:
- lora_speed_cross_digi
- lora_freq_cross_digi
- lora_automatic_cr_adaption
- lora_digipeating_mode
- lora_add_snr_rssi_to_path
- lora_cross_digipeating_mode
- acceptOwnLocationReportsViaKiss
- allow_gps_sleep_while_kiss
- acceptOwnPositionReportsViaKiss
- gps_allow_sleep_while_kiss
- added code for new preferences values
- in prepareAPRSFrame()
- beautified DST-path addition on outString
- better comment-ratelimiting computation
- loraSend(): small change.
- If lora freq was changed for sending one packet on another frequency (cross digi mode):
+ // cross-digipeating may have altered our RX-frequency. Revert frequency change needed for this transmission.
+ if (lora_FREQ != lora_freq)
+ rf95.setFrequency(lora_freq);
- FEATURE request:
// Feauture request: add param lora_speed. Currently, we need a variable for storing the old speed, and affer loraSend(), we have to revert :(
I did not change the function parametes without asking
- new sanity check:
+// enforce valid transmissions even on wrong configurations
+if (aprsSymbolTable.length() != 1)
+ aprsSymbolTable = String("/");
+if (aprsSymbol.length() != 1)
+ aprsSymbol = String("[");
+if (aprsLatPreset.length() != 8 || !(aprsLatPreset.endsWith("N") || aprsLatPreset.endsWith("S")) || aprsLatPreset.c_str()[4] != '.')
+ aprsLatPreset = String("0000.00N");
+if (aprsLonPreset.length() != 9 || !(aprsLonPreset.endsWith("E") || aprsLonPreset.endsWith("W")) || aprsLonPreset.c_str()[5] != '.')
+ aprsLonPreset = String("00000.00E");
-> Without this, and if unconfigured, invalid packets without position in the position-part of the AX.25 packets could occur. Saw this happens, at findu.com ;)
- encode_snr_rssi_in_path():
My idea of coding SNR and RSSI in packet path. Instead of modifying user's comment text (which some digi software does, and is a really bad idea)
- add_element_to_path():
a quick, string based option to add a digi element to the AX.25 header
- tnc_format_to_ax25_frame(): header parser, needed for handle_lora_frame_for_lora_digipeating
- handle_lora_frame_for_lora_digipeating: does header rewrite for digipeating
- implemented digipeating and cross-digipeating
- redesignt automatic cr-adatpion
- improved smart-beaconing decisions
5. taskWebServer.cpp:
---------------------
- added code for new preferences values
