We are currently using the STM32WL5MOC module and are facing a serious issue with LoRa range. The communication range is not going beyond 1 meter, and the RSSI while receiving TX data is in the range of -100 dBm to -115 dBm.
The same firmware and configuration work perfectly on the STM32WL55JC1 DK board, where we have tested both TX and RX successfully with good range and signal quality. However, with the STM32WL5MOC, using the exact same code, the range is very poor and the signal is too weak.
