LR1302 LoRaWAN Gateway: Data Not Reaching TTN Server

Raspberry Pi Gateways

Hello everyone,

I’m new to the world of LoRaWAN and have recently purchased the LR1302 gateway along with the hat for my Raspberry Pi. I’m excited to dive into this technology, but I’m facing a challenge that I hope you can help me with.

I am able to receive data successfully on the gateway, but unfortunately, it does not appear to connect to The Things Network (TTN). I’ve verified through a Wireshark capture that the data is being sent correctly from the gateway, but it still doesn’t show up as being online on the TTN dashboard.

Here are some details for reference:
