Sending a message on port 0

ChirpStack Network Server

Hello all,

I’,m trying to send a payload on port 0 to debug some MAC related answers from the device.

I tried using an API endpoint to send a message down on port 0. But looks like it doesn’t send any frame on port 0. Later on I found one line in documentation about sending a message down, that fPort should be >0.

Is there any way to send a message on port 0?

Any response is appreciated, thank you.

No, you can’t send anything on port: 0, you could however use the https://github.com/brocaar/loraserver/blob/master/api/ns/ns.proto#L83 LoRa Server API method for scheduling (custom) Mac-commands.
