Only receives the first message

[InternUSMC]

Hello,

I am using RPi and SX1276 (Hope RF95W) transceiver operating at 915 MHz. The packet forwarder only detects the first message and won't detect any consecutive message even after 30 minutes. The node is still sending messages every 30 seconds but the gateways can't detect them.

Any suggestion what might cause the gateway not to detect the message?

Thanks,

Quite old question but since I have a similar problem, I'd like to ask you, what authentication did you try for the node when you saw this behavior ABP or OTAA?
