The Raspberry Pi Pico, together with the RAK811, joining, sending, and receiving downlink(Only int implemented; for downlinks).
Set the DevEUI, AppEUI, and AppKey in config.py
For AT commands, error codes, and RAK811 information, see the RAK811 Breakout Board AT Command Manual.
The default setting is connected to UART1 on the pico, and the UART response timeout is set to 5 seconds.
Using just MicroPython, the pico is not a suitable MCU to use in an IoT device with a LoRaWAN connection. However, if the sleep modes provided in the pico-playground are integrated, the pico can achieve sleep mode current down to 0.8mA with the dormant mode and 1.3mA with the sleep mode. If the Saft LS14500 battery is used with a battery capacity of 2600mAh, the pico can achieve an estimated battery lifetime of 2.1 months in sleep mode.
