The Nucleo WL55JC board is LoRa capable board running on ARM CortexM0+ STM32WL55JC microcontroller.
It is possible to reset, debug and program the ARM Cortex M0 through the embedded debugger (ST-LINK) connected to the gateway USB port. This component also allows a UART connection to the M0.
IoT-LAB special configuration
The serial connection baudrate should be configured at 115200 bauds in the firmware.
