I am currently designing a board that uses the STM32WL55JCI7 LoRa functionality. I am currently using the AT_SLAVE firmware provided by ST for testing. I am currently trying to Transmit a signal through the Antenna on my board but no signal has been been coming through.
After some investigation I have noticed that the VR_PA voltage is stuck at 0V.
I am trying to transmit in Low Power mode, and the voltage on the other pins is as follows:
VDDRF = 3.3V
VDDPA = 1.55 V
This software has worked on a different variation of my board so I do not believe it is a firmware issue. I am trying to figure out why this particular board is not working.
