After send a downlink, the device shows: error: TX_FREQ

Good night.

When I’ve tried to send a downlink to an end device connected to MikroTik wAP LR9 with the Network Server ChirpStack, I saw the following error on Device Data:

error: “TX_FREQ”.

Someone nows what this error is?

I don’t know what to do, and nothing on the foruns solved my problem.


Does this help?

Thank you
But how can I know de downlink frequency being requested? And how can I change it?

If you are using UDP forwarder the global conf has tx min/max for allow tx range. The gw will validate the requested frequency is in range.

Basic Station will validate based on the region sent from the LNS.
