Having issues with STM32WL Nucleo-64. Device is not using antenna

LuisL · ‎2024-11-15

Hi, i have started testing the STM32WL Nucleo-64 with the Lorawan End Node Firmware. At first it seem to run OK, the device connects to the gateway and the data packets reach the platform i use. But the device stops working correctly with a few mwters of distance. I have seen that the BGS13S4N9 chip is not being powered, and the signals FE_CTRL1, FE_CTRL2 and FE_CTRL3 are always on reset state, though the firmware is setting them on.I have not modify the pinout or any configuration not needed. Is this a firmware configuration issue?

Kind Regards,

LuisL

Hi i have found the problem, i had the FE_CTRL pins not configured in stm32wlxx_nucleo_radio.h and stm32wlxx_nucleo_radio.c , now it works as intended

Hello @LuisL

I'm not able to reproduce this behavior. Could you try the same test using another NUCLEO-WL55JCx and see if you see the same behavior.

Best Regards.
