Hardware
- Raspberry Pi Model Model 3 B
- Sandbox Electronics LoRaGo Port on HAT
Software
- LoRa-net packet forwarder - poly_pkt_fwd
- Whoops, correction, I used this code TTN poly_pkt_fwd
- fresh install of Ubuntu 18.0.4.2 LTS
- fresh install of LoRa Server and all requisite software
Problem
- The End Node console says that it is requesting and joining the network continuously
- LoRa App Server UI says that a Join Request was received and accepted
- Activation never occurs
Symptoms observed
- Jun 20 22:39:58 wiriots00 lora-gateway-bridge[8398]: time=“2019-06-20T22:39:58-04:00” level=error msg=“apply gateway-configuration error” error=“gateway does not exist”
Troubleshooting attempted
- modified lora-gateway-bridge.toml as per a related topic, without success.
Here is my lora-gateway.bridge.toml file, does it appear to be correct?

# Example: 0.0.0.0:1700 to listen on port 1700 for all network interfaces.

# # The LoRa Gateway Bridge will only apply the configuration updates for this
# # gateway ID.
