Downlink is sent immediately instead of on next uplink

I’m having problems being able to send a Download message to a node, via MQQT.

I’m sending to this topic

“confirmed”: true,
“fPort”: 1,
“data”: “MTIzNDU2Nzg5MA==”

The data here is “1234567890” ( base 64 encoded )… When i publish it, i immediately get an event on the server, and it sends that to my gateway.

My node of course is not listening ( its class A ). My understanding is that the device should get this mesasge when its next sends something.

You probably have “Supports Class-C” checked in the device-profile.

So I did! Thanks so much. Now sorted! Next to test actual multicast / class C
