I bought 2 of this, and after flashing them and using the small antena, seems that one of them only recognizes the other than is in my house, however after some time it started to recognize a lot of them near me, but suddenly after changing it position it doesn’t see any other node, how can I see if it’s burnt or something?
It's the radio of my Heltec v3 lora 32 burnt?
We probably need a bit more information to be able to help in any meaningful way. For starters, are you using LoRaWAN or just LoRa? What frequency? Do you have the correct board model for that frequency?
