ChirpStack Gateway Bridge Config Problem [AWS Ubuntu - RAK7258]

ChirpStack Gateway Bridge
1

Good day,
I have a problem where my gateway-bridge** where there are errors initially then it connects to the the UDP and MQTT in an unstable way** as seen below:

Here is the actual terminal results:

ubuntu@ip-172-31-41-91 : ~ $ journalctl -u chirpstack-gateway-bridge -f -n 50

My main problem could be I have the wrong config file (.toml), do you think that is the problem?

Notes: I followed the tutorial here

ANY AND ALL HELP IS APPRECIATED

Possible you have the termination on connection error set to true?

  # Terminate on connect error.
  #
  # When set to true, instead of re-trying to connect, the ChirpStack Gateway Bridge
  # process will be terminated on a connection error.
  terminate_on_connect_error=true

Is the mqtt broker on localhost? Odd that it would have an issue connecting if so.

Hello John!

I realized that the above are logs thus showing initial errors, now everything seems to be working fine EXCEPT the Gateway is still not connecting to ChirpStack and I am honestly lost.

ALL tests giving the expected results, namely:

  • journalctl -u chirpstack-network-server -f -n 50
  • journalctl -u chirpstack-application-server -f -n 50
    journalctl -u chirpstack-gateway-bridge -f -n 50

All of them are running as seen below:

ALL indicate that they are online and running.

Anyone has any clue why this is happening?

My System log seems good

I haven’t changed my chirpstack- network-server from its default to US915… but would that impact the gateway being found by the chirpstack server hosted on AWS?initial errors, now everything seems to be working fine EXCEPT the Gateway is still not connecting to ChirpStack and I am honestly lost.

When I execute: journalctl -u chirpstack-gateway-bridge -f -n 50
I receive errors (logs from when I tried lora-server instead of chirpstack-gateway-bridge)

But thankfully it is connected to the MQTT.

For Chirpstack-Network-Server:
journalctl -u chirpstack-network-server -f -n 50

Which seems weird but when I check status, it is running ->

Hey Brian. Nothing is standing out to me in the logs you’ve shared.

I did encounter an issue where my gateway’s weren’t being seen because the date/time on them was in the past. Could you check that?

Good Sunday John, yes I checked it :frowning: and it is in sync so that is not the problem.

FOUND THE PROBLEM

Are you ready for this…

I did not set my Semtech Packet Forwarder to UDP but rather I had TCP.
A week and a half later. Whoops.

Ls stand for lessons

Ah! Glad you found it. It’s funny how it seems these things are often a “minor” thing overlooked. Again, really glad to hear you found it
