Sending MAC Commands from ChirpStack to LoRa Device

1

I want to send a MAC command via ChirpStack. I tried sending it through the queue interface, but I couldn’t choose FPort = 0. Is there any other solution to send the MAC command from ChirpStack to the LoRa device?

This is not a normal thing and is not supported via the usual methods of sending downlinks. What’s your usecase?

You can’t.

But

a. You can receive a MAC command (Rx Parameters) with the join.
b. or if you jump the framecounter (you will receive NbTrans MAC command > 1),
c. or you can configure in device profile to receive a Device-status request frequency (req/day)
d. or close to a GW with SF > 7 and ADR enabled on your device you will receive an ADR command.
e. or issue TimeReq or LinkCheck from device.

ATTENTION: all those are suggested for testing, not for production.
