High priority

MVP features required for first public alpha

• do setOwner every time we connect to the radio, use our settings
• send location data for devices that don't have a GPS - https://developer.android.com/training/location/change-location-settings
• make nodeinfo card not look like ass
• when a text arrives, move that node info card to the bottom on the window - put the text to the left of the card. with a small arrow/distance/shortname
• all chat in the app defaults to group chat
• make my android app show mesh state
• add app icon
• when notified phone should automatically download messages
• at connect we might receive messages before finished downloading the nodeinfo. In that case, process those messages later
• use https://codelabs.developers.google.com/codelabs/jetpack-compose-basics/#4 to show service state
• connect to bluetooth device automatically using minimum power - start looking at phone boot
• fix BT device scanning
• call crashlytics from exceptionReporter!!! currently not logging failures caught there
• show direction and distance on the nodeinfo cards
• test with oldest compatible android in emulator (see below for testing with hardware)
• make playstore entry

Signal alpha release

Do this "Signal app compatible" release relatively soon after the alpha release of the android app.

• add large packet reassembly?
• optionally turn off crypto in signal - preferably though see if there is a nice way to be a peer of signal/sms and now mesh.
• change signal package ID - if distributing modified binary
• investigate the Signal SMS message flow path, see if I could just make Mesh a third peer to signal & sms?
• make signal work when there is no internet up
• make Signal rx path work
• send Signal message type. It seems to be? " public static final int WHISPER_TYPE = 2; public static final int PREKEY_TYPE = 3; public static final int SENDERKEY_TYPE = 4; public static final int SENDERKEY_DISTRIBUTION_TYPE = 5;"

Medium priority

Things for the betaish period.

• let user change radio params and share radio join info via QR code or text message (use an encoded app specific URL - to autoprompt for app installation as needed)
• test with an oldish android release using real hardware
• if necessary restart entire BT adapter with this tip from Michael https://stackoverflow.com/questions/35103701/ble-android-onconnectionstatechange-not-being-called
• stop using a foreground service
• change info() log strings to debug()
• use platform theme (dark or light)
• remove mixpanel analytics
• require user auth to pair with the device (i.e. press button on device to allow a new phone to pair with it). Don't leave device discoverable. Don't let unpaired users do things with device
• if the rxpacket queue on the device overflows (because android hasn't connected in a while) send a special packet to android which means 'X packets have been dropped because you were offline' -drop oldest packets first

Low priority

** make analytics optional

• also add a receiver that fires after a new update was installed from the play store

Done

• DONE fix bluetooth update
• DONE refactor sw update code to share with my other bluetooth service
• DONE don't let sw update got to sleep during the update
• assert() is apparently a noop - change to use my version of assert
• DONE add crash reporting
• DONE add analytics (make them optional)
• make frontend using https://developer.android.com/jetpack/compose/tutorial
• change bluetooth mtu length to 512 (default is only 20)
• DONE get signal running under debugger
• Find good Signal hooks
• receive fake packets at power on to built initial state (for debugging, pretend there are a couple of nodes out there)
• learn our node number
• test mesh service from activity
• DONE handle failures in onCharWrite, instead of logAssert - because they can happen if device goes away
• DONE explictly broadcast towards signal https://developer.android.com/guide/components/broadcasts
• make test implementation of android service (doesn't use bluetooth)
• undo base64
• use android service from Signal
• send signal message type over wire
• DONE add broadcasters for use by signal (node changes and packet received)
• DONE have signal declare receivers: https://developer.android.com/guide/components/broadcasts#manifest-declared-receivers
• fix // FIXME hack for now - throw IdNotFoundException(id) in MeshService
• clean up sw update code in device side
• add real messaging code/protobufs
• implement android side of mesh radio bluetooth link
• use the lora net code on my current protoboard
• investigate a 16 bit node number. If possible it would make collisions super rare. Much easier to just pick a nodenum and go.
• remove example code boilerplate from the service
• switch from protobuf-java to protobuf-javalite - much faster and smaller, just no JSON debug printing
• have phone use our local node number as its node number (instead of hardwired)
• if radio disconnects, we need to requeue a new connect attempt in RadioService
• don't do mesh based algoritm for node id assignment (initially) - instead just store in flash - possibly even in the initial alpha release do this hack
• show connection state on gui
• parcels are busted - something wrong with the Parcelize kotlin magic
