this is something that has been already discussed in this forum but even with the posts that i found that talks about this, I cannot success to downlink a message using NodeRed with the “MQTT out” node.
I can read data from my sensors with the “MQTT in” node, the configuration of “MQTT out” are quite the same so I guess the problem does not come from the server.
This is an exemple of the message sent to my MQTT out node :
my function node :
I send it to v3/hubis@ttn/devices/eui-0004a30b00f50d7d/down
I don’t see anything on my terminal node. Note that my node receive data if I use the console
Can you guys see some problem ? I suspect a js problem (as this is not my favorite language)
