STM32WL5MOC no transmit

Hello,

I have developed a breakout board for the STM32WL5MOC for development purposes and it uses both rf switches and the wiring is identical to the B-WL5M-SUBG1 evaluation board.

Running the B-WL5M-SUBG1 sample application SubGhz_Phy on my board and I can only receive, but the board does not send anything. This applies to both LoRa and FSK. The output of the USART debugging looks identical.

My board does not contain any of the sensors of the B-WL5M-SUBG1 board. Is this likely to be an issue with my circuit board or is there anything in the software that I need to adapt? I am using the STM32WL5MOCH6TR version.

Thank you,

Daniel

I found the problem: It was an issue in association with soldering the components.

TX now works as expected.

ST, you have done a great job with the STM32WL5MOC, enabling me to develop a smaller device with less components.

 

Regards
