Here’s a thread back in 2019 that might help. It’s getting confusing for me !

Using LoRa (transparent transmission) by Ebyte as UART radio

Dears, I am using two emlid reach M+ since Augst as RTK device for field sampling. I started using two cheap 3DR radio:" RS232 TTL UART Wireless Transceiver Module for Arduino DUE MEGA2560 3DR Radio" to allow communication between the rover and the base. [here you can find the description : 2x RS232 TTL UART Wireless Transceiver Module for arduiuo DUE MEGA2560 3DR Radio | eBay] Everything works fine. I linked the S1 using the red, black, yellow and blue pin in VCC,GND,TXD and RXD. Then, I tr…
