Device not registered on ChirpStack

[itarozzi]

I created 1 virtual GW and 1 virtual device on LWM, and redirected gateway bridge to my NAS executing ChirpStack. All on the same local network.

I can see the virtual gateway active on ChirpStack Dashboard (with localization ok).

Under the device detail on CS dashboard I can see activation data and LoRaWAN frames, but only JOIN_REQUEST/JOIN_ACCEPT ... no downlink/uplink messagge .

I reported the simulator console output. I can't understand if the problem is the simulator or the server. Seems the JOIN_accepted message is not received, but I'm not sure.

Same executing lwm simulator with make run or docker

Hi thank you for the notice, we are going to check the issue on OTAA join

[fedyfausto]

Seems that something is broken on source code because the built on works well, can you confirm this?

[itarozzi]

Yes, I can confirm the release v1.0.2beta (lwnsimulator_x64.zip ) works great.

I also downloaded the source tarball from release page, compiled and executed with make run, and again it works well.

[fedyfausto]

ok then I will check the problem into the all commits xD

Any solution to this bug? I installed this week the simulator and i have this problem too. I only view the Gateway. I can see the LoRaWAN frames (join request and accept) but no data coming from the sensor.

[NuwanUdara]

Any updates on this issue? Is there at leat a temporary workaround.

[DmSilkin]

Hi, is there any solution?

[fedyfausto]

Did you try the 1.0.2 version from the releases?
