Gateway don't use new frequency plan

Long story short. I’m trying to implement a new “non standard” frequency plan because I got a lot a interference around 867 Mhz.

I have decided to use the following frequencies:

channel 0: 868100000 (868.1)
channel 1: 868300000 (863.3)
channel 2: 868500000 (868.5)
channel 3: 868700000 (868.7)
channel 4: 868900000 (868.9)
channel 5: 869100000 (869.1)
channel 6: 869300000 (869.3)
channel 7: 869500000 (869.5)

I’m getting the new frequencies on my end device. My challenge is that my gateway (Kerlink ifemtocell) are not using my new frequencies.

I have installed the gateway bridge on my local ubuntu machine, where the AS and NS is also running. I have added the extra channels in chirpstack-network-server.toml

[[network_server.network_settings.extra_channels]]
frequency=868700000
min_dr=0
max_dr=5

[[network_server.network_settings.extra_channels]]
frequency=868900000
min_dr=0
max_dr=5

[[network_server.network_settings.extra_channels]]
frequency=869100000
min_dr=0
max_dr=5

[[network_server.network_settings.extra_channels]]
frequency=869300000
min_dr=0
max_dr=5

[[network_server.network_settings.extra_channels]]
frequency=869500000
min_dr=0
max_dr=5

and added the extra channels under Gateway profiles. When my end device is sending an uplink via the 867.1/867.3/867.5 the NS will receive it. When it tries to use the extra channels, the gateway won’t forward the payload. If I look under gateway and live lorawan frames, I can see that my gateway is receiving payloads from other end devices on the std. EU frequencies (867.1/867.3/867.5/867.7/867.9). I thought my gateway would download the new frequency plan from the NS? My gateway is using the CPF.

Wrong assumption. The gateway will only be configured from the NS(+Gatewab-Brige) IFF using chirpstack-concentratord or BasicStation. Every other setup needs to configure the gateway with the wanted frequencies. The NS still needs the extra channel config thou, else it wont know about the used frequencies.

Thank you :slight_smile: I got my gateway configured the frequency plan on the gateway, and everything works like it should.
