I guess from the lack of comment that this is not something that will work with NodeRed running on ChirpstackOS? I’ve trawled though various settings files, tried editing the groups file to add ‘nodered’ or ‘node-red’ to the dialout group but no success.
For info when the serial port tries to connect the NodeRed application stalls - ‘no response from server message’ or something to that effect. We have to then edit the ‘flows.json’ file to change the port to something non existent for the application to work again (without the serial port with status showing as ‘not connected’).
I have the same infrastructure, and it doesn’t work. Strange. Here is why.
I tried with two RPis 4B, one with 8GB RAM and the second with 4GB.
With the same effect.
@brocaar any comments on this one? is it an Rpi configuration problem or does it require a new / custom image ‘build’ (or whatever the docker term is ) of CsOS?
Node-Red was dead, and I can’t restart it from the Open-Wrt System->Startup->node-red.
I added only one component serial input request, and it was gone.
