Hello, I did some forum search and understood that the gateway was too close to node, so I moved them a bit and now this is the new Logread RxTXJson of the gateway

Is 25% failed CRC too much?
The YAT terminal is same as before

And I could not find any detailed discussion or documentation about CRC failure of LoRa, where I can find some? Thank You.
