Hi Thorsten,

yes, as Yves has written, you can send it easily by publishing a MQTT message to the MQTT broker on your gateway.

If you subscribe to the broker using e.g. mosquitto_sub, you can see the format of data. E.g. run this on your Raspberry PI:

$ mosquitto_sub -h localhost -t ‘dwm/node/+/downlink/#’

and then send some user data via the Web Manager. You should see something like:

dwm/node/11cb/downlink/data {“data”:“ASNFZ4mrze8=”,“overwrite”:false}

Similarily you can publish using mosquitto_pub or other MQTT client so the data would be forwarded to the module. E.g.:
echo ‘{“data”:“ASNFZ4mrze8=”,“overwrite”:false}’ | mosquitto_pub -h localhost -p 1883 -t ‘dwm/node/11cb/downlink/data’ -l

Cheers,
TDK
