Hello. I’m using 2 Heltec WiFi LoRa 32 (V2) to implement the LoRaWAN architecture, using one as a Node and the other as a Gateway.
At the gateway, I have implemented the single-channel LoRa Gateway code from THINGS4U (https://github.com/things4u/ESP-1ch-Gateway-v5.0), and it seems to be running well.
At the node, I’m using LMIC Arduino Library, using ttn-abp example as base. The problem is: only a few packets are arriving at the Gateway (The messages received are displayed at OLED display) and at TTN Server.
What usually happens is: Packet with counter = 0 is received, then counter = 3, then counter = 6, and then it goes… at this screenshot, it has started at counter = 9 . (The first byte of the payload is increased every package sent by the node, so its the same as the counter). At Node’s serial debug, the functions that send data seems to be working correctly ( it says “EV_TXCOMPLETE (includes waiting for RX windows)” as expected).
Has this ever happened to anyone? I can’t find the problem.
