ABP works only first time

Good afternoon,

I am testing ABP on an ESP32 + RMF95W LoRa node using TTN. I only receive data on the first attempt after registering the device. However, after the first attempt, I see node data popping up on my gateway Live Data, but it does not appear on the node Live Data, and it does not give any error at Live Data or over the serial console.

Sometimes, if I “Reset session and MAC state”, sent data appears again in Node’s live data section. This does not always work. I have tried to enable “Resets frame counters”, but it does not change anything.

It can’t be a signal strength issue because I’m really close to my gateway,

I don’t know what else could I try.

Best regards, Ander.
