Hi All, A guy I am helping out has a RAK831/Rapsberry Pi setup working well on AU915 using Balena. (using @kersing ’s Multi Protocol (MP) Packet Forwarder) He ordered some off the shelf temp/hum nodes that he now realises operates on AS923. I believe the hardware should be capable of switching ove…

Could it be this? [image] RPi + RAK831 + Resin image => Failed to start the concentrator Raspberry Pi Gateways Hi, I followed the instructions on the TTN page here: https://www.thethingsnetwork.org/docs/gateways/rak831/ Unfortunately, all I get is the dreaded “failed to …

Yes, AS923 with the MP packet forwarder and RAK831 doesn’t work. You must disable LBT, then it should be fine.

I tried the disabling LBT by inserting those lines into run.py at 191 but it had no effect. Restarted and rebooted just in case, but same error. Switching back to AU915 and it all runs again. Any other ideas? @tuftec I see you have/had a RAK831 running on AS923, what was your setup? cheers Pau…

Are you sure you correctly pushed the balena image and then deployed it to your device? Did you check your log to see if it printed “Removing LBT configuration” during startup ? I have 3x RAK831 gateways working fine on AS923 with this change.

Actually I used the terminal within Balena to insert the lines with nano. Won’t that work also or have I stuffed up? (I am trying minimal impact stuff at the moment because the gateway is 450km away) cheers Paul

@paul I just used the original packet forwarder that comes with the standard RAK831 setup. I found that the AS923 band plan was pretty easy to setup and worked well. I will try to send a PM with my conf file.

I’m not 100% sure how the balena system works here, so I’m not sure if it would automatically override your changes with those from your image. I’d try looking in the console to see if that line is printed; if it isn’t, your changes didn’t stick.

OK changes don’t stick, must be recopied each time from some repository. We modified the version of run.py with those extra lines on the local hard drive and did the update via these lines as per the readme git add . git commit -m "Updated gateway version" git push -f balena master Then what? (so…

See here for a guide: https://www.balena.io/docs/learn/getting-started/raspberrypi3/nodejs/ It’s not exactly the same, but it is roughly similar to what you are doing. Once you push the code to git, you should be able to just reboot the device and it will re-provision. It might even do it automati…

No need to reboot, the device will pull the new image and start it automatically after some time. Paul, do you see a new build cycle starting at the push? It should end with ascii graphics if successful.
