Problem in Node-Red sending downlink messages to end device

Application Development
1

Hello,

I am trying to use node-red to send downlink messages to my end device. I did as the documentation said, but I cannot see any downlink messages in my “Live Data”. (By the way, the uplink goes well.)

Here is my flow for downlink.

app id : aircov-iot device id : wlr089u0

Topic : v3/aircov-iot/devices/wlr089u0/down/push

Any idea where I do wrong? Maybe there shouldn’t be an hyphen in app id?

You are missing the tenant id:
