RAK RS485 module in conflict with GSM Module


Our actual application needs the use of both modules RAK 5802 (RS-485) and RAK 13101 (GSM Module). However, both modules communicate with UART, that generates conflict not letting one of the modules to work properly. Is there a way to multiplex the UART in the RAK13101, or select which module will receive the message.

Unfortunately there is no way to “multiplex” the UART. You can connect only one module with UART at a time.
