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.
