923-2 Region, one of the default channels is not working after latest update (921.2) #565

Closed BerdinEge closed 2 years ago

What happened?

Device LoRaWAN MAC version 1.0.2, LoRaWAN Regional Parameters revision B, Default ADR algorithm.

After latest release one of the default frequences of 923-2 region is not working. 923-2 region has 2 default channels: 921.2 and 921.4. In the Lorawan Frames screen of the Device, we can see uplinks from 921.4 but we can not see uplinks from 921.2. We are seeing both channels' uplinks in Gateway's Live Frames screen. We were seeing the uplinks from 921.2 channel in erlier releases of chirpstack in Device's Lorawan Frames screen. I think the issue is about the newest release.

What did you expect?

We are expecting to see uplinks from 921.2 channel in Device's Lorawan Frames screen.

Steps to reproduce this issue

Steps:

  1. Arrange your NS, AS and Gateway bridge to handle AS923-2 region.
  2. Open Chirpstack, open your Gateway's Live Lorawan Frames screen and Device's Lowaran Frames screen.
  3. Send uplinks from the device. It should send packets with default channels. Default channels are 921.2 and 921.4. No need to add extra channel.
  4. The uplinks coming from the 921.4 frequency are seen in both, the gateways frames and devices frames screens. But the uplinks coming from the 921.2 frequency is just seen in the gateways frames screen.

Your Environment

Lorawan 923-2 region has 921.4 and 921.6 channels as default, Not 921.2.
