How do I get downlinks from the mqtt broker

If the device sends uplinks via the mqtt broker, you can retrieve the downlinks sent to this device by the IOT factory platform.

To do this, you need to create an mqtt client. It must first open a connection to the mqtt broker and then subscribe to the downlink topic linked to the device

sub/{user}/{device id}/request

Refer to your credentials generated in the mqtt broker settngs module.
