High priority

• watch for ntofies of numread changing
• implement android side of mesh radio bluetooth link
• 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;"
• 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
• 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.
• add large packet reassembly?
• optionally turn off crypto in signal
• change signal package ID
• good tips on which bands might be more free https://github.com/TheThingsNetwork/ttn/issues/119
• make my android app show mesh state
• use https://codelabs.developers.google.com/codelabs/jetpack-compose-basics/#4 to show service state
• connect to bluetooth device automatically using minimum power
• fix BT device scanning
• call crashlytics from exceptionReporter!!! currently not logging failures caught there

protobuf notes protoc -I=. --java_out /tmp mesh.proto

to generate nanopb c code /home/kevinh/packages/nanopb-0.4.0-linux-x86/generator-bin/protoc --nanopb_out=/tmp -I=app/src/main/proto mesh.proto https://jpa.kapsi.fi/nanopb/docs/

nanopb binaries available here: https://jpa.kapsi.fi/nanopb/download/ use nanopb 0.4.0

Medium priority

• 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
• remove example code boilerplate from the service
• switch from protobuf-java to protobuf-javalite - much faster and smaller, just no JSON debug printing

Low priority

• make analytics optional
• possibly use finotes for analytics https://finotes.com/
• also add a receiver that fires after a new update was installed from the play stoe

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
