How to connect Chirpstack device and generate testing data from simulator device?

[zhgchen]

I have copied DevEUI to Chirpstack's device. The gateway can be associated correctly. But "Last seen at" is always "never" for device.

Do the Gateway and devices work?

Gateway seems work and is visible at "Active gateways", but device is not available at "Active devices"

Might be a little late but here's how I got it working:

1. Configure device in Simulator
2. Create a device in Chirpstack
3. Then use Chripstack API Endpoint to first get a JWD-Token via [POST] [/api/internal/login] and then use route [GET][/api/devices/{dev_eui}/activation] to activate your device manually.

If anyone is using Europe to testing their devices I got it working by changing device region from EU433 to EU868.

The frequency must be the same on the Chirpstack and in the Simulator. The device auth is ABP?

Closing the issue, I think the problem was solved
