Share your GPS location from your phone with other Flippers via SubGHz
This is a very simple Serial-over-Bluetooth app for Flipper Zero. You can use it (but better not to :D) as a reference app for building your own solutions.
This application hijacks the default Serial-over-Bluetooth connection of a Flipper Zero device (that is usually used for communication with mobile app) and set a custom callback on data received over the connection. Therefore, by modifying this app you can implement your own custom logic on using Serial connection over Bluetooth. As an example - see this repository: https://github.com/maybe-hello-world/flipper-bp
- Optional: enable debug log on the Flipper device: System - Log level - Debug
- Compile and upload the app on the flipper.
- Enable bluetooth and pair your device with the flipper.
- Run the application on the flipper (optionally: connect flipper via usb and use
fbt cli -> logto observe the logs) - On your device launch an app that supports serial profile over bluetooth (e.g., for Linux: bluetoothctl) and use these channels for connection:
tx: 19ed82ae-ed21-4c9d-4145-228e62fe0000
rx: 19ed82ae-ed21-4c9d-4145-228e61fe0000
Specifically, try to write into tx channel some bytes.
5. Observe bytes received on the Flipper's side.
- Optional: find a normal Flipper Bluetooth Serial reference app instead of this junk. If it's impossible - go to step 1.
- The application substites the default serial callback of the Flipper RPC connection. In the fbs.c modify the
bt_serial_event_callbackfunction to introduce your own custom logic of processing the data received (or sent) over Bluetooth.
