RAK 831 + Rasp ERROR: [main] failed to start the concentrator

khomkrit · July 28, 2019, 2:17am

I found problem to start RAK831 gateway
Normally I use freq: 923-925 Mhz as a long time no problem heppen
but last 2 day ago Resin.io show status “02:09:10 ERROR: [main] failed to start the concentrator”

I try to change router server to another but error that still show
but If I change freg plan to 915 mhz Gateway start normally

How I can solve this problem?

How are you managing the concentartors’s reset?

For the configuration that works, can you repeatedly kill it and restart it reliably?

khomkrit · July 28, 2019, 3:44am

I try to restart from belena.io but it not work properly

That’s not meaningful, because the configuration you attempted to restart is the non-working one.

The question was if you could repeatedly kill and restart the working configuration many times in a row without failure?

khomkrit · July 28, 2019, 6:43am

I use this gateway from May 2019 to last 2 day ago.

but now it not work.

I try test send with frq au915 gateway it work
but when i change to as923 gateway still [ERROR: [main] failed to start the concentrator]

cslorabox · July 29, 2019, 3:42am

Again, can you start and stop it over and over and over again many times with no failures? You need to do that to rule out coincidence of an unreliable startup procedure.

If the working configuration always works in many trials, then do a line by line comparison of the config files. Start removing the differences one by one until you find what makes the difference.

khomkrit · July 29, 2019, 5:41am

thank you indeed.
I try more …

kersing · July 29, 2019, 8:07am

Are you sure your hardware supports Listen Before Talk? If I recall correctly that is a difference between AU915 and AS923.

Mmmmh…
Afaik the RAK831 does not support LBT…
You might have it running on a frequency plan which had LBT disabled at that time…
