Payload Message sent by uplink in the Gateway

Hi Franco,

what do you mean with writing? Do you mean to publish data to the node? If so, you need to publish to the downlink topic, see this post:

Downlink data from bridge to tag

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 mo…

Another MQTT library option is to use Mosquitto libraries:
