Hello together, I need some help understanding how to get the IC880A running with the Full Chirpstack OS.
What I have done:
Followed Getting started - ChirpStack open-source LoRaWAN® Network Server documentation until and including “Configure Concentratord”.
HW is connected following Building a gateway with Raspberry Pi and IC880A | The Things Stack for LoRaWAN and https://www.instructables.com/Raspberry-Pi-LoRaWAN-Gateway/
What do I see:
Using logread: This in a loop every 5 seconds

Questions:
Is there any documentation on how to modify the reset pin? According to the log above, its using pin 5 as reset pin. But according to the two tutorials regarding I linked above, it should be pin 22.
According to https://github.com/chirpstack/chirpstack-concentratord/issues/11 it should be possible. I added option reset_pin 22 or option sx1301_reset_pin 22 to /etc/config/chirpstack-concentrator without any change in the above log.
Should I be worried, that the log above in the third line it says Triggering sx1302 reset ?
Is there any documentation about the expected pin assignement when using the IC880A? Can someone confirm that the wiring above is correct?
I guess that the communication to the shield is not working, either because of configuriation or wiring issues. Is there any way to get more detailled logs about the communication attempt that would help me debug this issue? The logread is quite high-level. I tried changing the /var/etc/chirpstack-concentratord/concentratord.toml log_level setting. Then I discovered that this is overwritten by /lib/functions/chirpstack-concentrator.sh. However, changing it there, also did not lead to any result.
