Hello. I have two ESP32 V2 Heltec LoRa boards.
I am able to send strings to a receiver and do things.
I would like the receiver to echo RSSI back to the transmitter (which will momentarily become a receiver). I have tried a lot of things but can seem to get it to work. I understand it is half duplex, but I would like to switch the state of both from one to the other, transmit/receive, and then back to be able to monitor RSSI on the remote end.
