I think I have a decent setup (heltec v3, 3000mah battery, aftermarket antenna) yet I struggle to make contact with anyone. I'm a little confused as I do receive messages on the general the Long-Fast channel but my messages never seem to send or be acknowledged. Am I doing something wrong or is this just the nature if radio comms?
I have not connected to MQTT. I'll have to look into that as I didn't know where to start with it.
