CSGOS IC880A Reset Pin

sdavid63 · February 12, 2024, 7:35am

Hello,

I have a gateway with ChirpStack Gateway OS v4.3.2 for Raspberry Pi 3B/3B+ (full image) with my own concentrator similar to IC880A / SPI mode but i need to change the reset pin to gpio25.
Global Configuration = sx1301
Shield Mode = IC880A
I would like to know how to change the reset_pin number for an ic880a concentrator board.

Regards

Stephane

Hi !
I have the same issue, reset pin is 5 but need to change to 25, I have a shield board between the rapi 3 and ic 880A, apparently the file to change is /dev/gpiochi0 but i dont know how to change on openwrt, then it enters in a loop of restart :

This is currently not possible when using the ChirpStack Gateway OS. While the config option exists in the Concentratord for the SX1301, this configuration is not (yet) implemented int the GW OS UCI configuration (which is used to generate the TOML configuration).

Could you create a feature-request here:

E.g. for the SX1302/3 this is already supported from the CLI (by directly editing the /etc/config/chirpstack-concentratord config file):
