Hi,
I use concentratord and mqtt forwarder on a kerlink istation gateway with keros 5.
Concentratord works perfectly (although intended for the ifemtocell model) however, the gnss positioning does not go back to chirpstack.
I tried several settings of the concentratord.toml file but I can’t get the gps to go back.
Is this a bug or is it not functional at all for this hardware?
hardware the gateway has a gps chip. The nmea frames are accessible here /dev/nmea1 ( and 2 3 )
tested settings :
/etc/chirpstack-concentratord/concentratord.toml
[gateway]
region = "EU868"
model = "kerlink_ifemtocell"
model_flags = ["GNSS"]
try to change:
gnss_dev_path="/dev/gps0"
or
gnss_dev_path="/dev/nmea1"
but not work
Static location work perfectly on concentratord.toml
example of cat /dev/nmea1 :

Are there other leads that could help me?
