@magixyu If I understand correctly, You want to use a script to send messages to other connections.

But sorry,MQTT X don't support cross connection message publish now.

It is a good idea that script could handle different connections, such as get some message send message to test/1 by script. Maybe it could be like this:

function handlePayload(value) {
  if(value.msg === 1024){
    MqttxApi.pub('test/1', "hello world")  //send hello world to test/1 topic 
  }
  return value.msg // send value.message to current topic
}

execute(handlePayload)

I would like to send to the same connection but different topic. Like I receive an message from /topic1, then the tool automatically send back to /topic1_reply with certain content.
