Crash when receiving configuration command? #114

Closed cyclops1982 closed 5 months ago

cyclops1982 commented 11 months ago

What happened?

chirpstack-concentratord-sx1302 crashes stops/crashes when it receives a 'Configuration' command.

What did you expect?

That it keeps running :)

Steps to reproduce this issue

I've installed the chirpstack-concentratord-sx1302 and the mqtt forwarder. I've linked these two together (config's below). My docker deployed chirpstack is on another machine, so the mqtt forwarder connects to that.

It seems that on update from chirpstack, a configuration is passed along to the concentrator and then it crashes.

Could you share your log output?

The reconfiguration might not be the issue:

thread '' panicked at 'read from gps error: Error { kind: UnexpectedEof, message: "failed to fill whole buffer" }', chirpstack-concentratord-sx1302/src/handler/gps.rs:75:14

Could you please try without the GPS / GNSS enabled?

cyclops1982 commented 10 months ago

Without GNSS it has been working fine.

I'm wondering how RAK5146 should do GNSS. I have the module that has it built in and the antenna is connected.

brocaar commented 6 months ago

The module works fine for me. Assuming you are using a Raspberry Pi, have you tested with the ChirpStack Gateway OS? Please note that you need to make some Raspberry Pi config changes to make the GNSS work (by default the Bluetooth module is mapped to the UART pins, which collides with the GNSS).
