Esp-32 and LoRa ra-02 – send and receive loop not working
I have two sets of ESP-32 and Ra-02 LoRa module. I want to send a message from one node to the other and get the reply back. Sending a message from node1 to node2 reaches node2. But sending the reply message from node2 to node1 is not happening. Am I missing something here.
