unfortunately, I have some problems with my RAK7289C now after a couple of months of usage. It was working fine for months and then suddenly it stopped working.
In the logs I can only find this error:
ERROR: [main] failed to start the concentrator
I tried both the Packet Forwarder and Basic Station. There is no difference. Both don´t work. I updated the firmware to the latest one. That also didn´t make a difference.
Did someone else encounter this error before? I would gladly appreciate any help.
