# RAK811 Tracker Board mbed test

## Compilation

Clone this repository, then :

```
mbed deploy
# modify lora.device-eui, lora.application-eui and lora.application-key in mbed_app.json
mbed compile --profile mbed-os/tools/profiles/release.json
```

Then you can use stm32flash or may be better a stlink interface to copy the generated .bin file onto the RAK811.

## Notes

### use STLink from a Nucleo board

From STlink CN4 Connector to RAK811 "shortest" connector (pin 1 at the same side of antenna connectors)

```
2 -> 3 (CLK)
3 -> 1 (GND)
4 -> 4 (DATA)
5 -> 2 (RST)
```
