I’m trying to schedule some messages into the queue of some devices. I tried first using the API and it works as you can see below:
In the GUI it can be seen the packet scheduled:
Then I tried to send the downlink by MQTT and the message is sent to the server:
However the packet is never scheduled. I receive the following error on the logs:
Jan 27 10:16:36 ip-172-31-40-30 chirpstack-application-server: time=“2020-01-27T10:16:36Z” level=error msg=“integration/mqtt: fPort must be between 1 - 224” dev_eui=XXX f_port=0 topic=application/1/device/XXX/tx
And as you can see, the “fPort” parameter is set to 2, not to 0 as you can see at the logs…
Any idea @brocaar or somebody?
Thanks in advance.
