I would like to use RAK3172 in SubGhz mode without lorawan stack.
- created project using STM32Cube IDE for STM32WLE55.
- configured UART1 in Asynchronous 115200, 8N1
- Flashed the chip using USB-UART connector and STM32CubeProgrammer (by the way ST-Link doesn’t work even when boot0 connected to ground and Reset connected properly)
- The main problem no data on the UART1 Tx pin.
What could go wrong in such an easy configuration?
