- BT can just act as a serial device - there's an android app here: https://play.google.com/store/apps/details?id=de.kai_morich.serial_bluetooth_terminal&hl=en_GB&gl=US
- Here's the wisblock example: https://github.com/RAKWireless/WisBlock/tree/master/examples/RAK4630/communications/BLE/ble_uart
What we need to test:
- Can we turn on BT at startup and be fast enough to connect to it in the /first/ update?
- Can we work without antenna? We should do low power, but still..
We currently have flash that stores some configuration. We also have a hardcoded lora settings, like the deveui and the app keys.
Ideally ,we want a device that we can flash and /then/ configure the lora settings and store those in flash.
The device has BT, and although we typically do not connect a antenna to that, we could check if we can still listen/receive BT data if another device is close.
We could then flash the device and if there's no lora settings, we could go into 'BT receiver mode'. This would then allow us to send lora settings /to/ the device. After it has these lora settings, it can go out of BT mode and just be on lora.
There might be a nice option where a failed join (10 times or so?), it goes into BT mode as well?
We can also consider other settings via BT, but that's maybe a nice-to-have as the other configuration would go via lora anyway.
