I'm trying to help a customer connect their Mosquitto bridge to Azure IoT Edge. They have some legacy equipment that speaks MQTT, but because it can't do TLS and the topics can't be changed, we are trying to run the messages through the Mosquitto MQTT Broker, and over to IoT Edge via the Mosquitto bridge...
I've had no problems getting the actual connection made from the bridge to IoT Edge and I have messages flowing to the bridge. That connectivity works fine. The problem comes in the topics. I really can't change the topic structure that the client publish on. However, IoT Edge requires messages to be published on a specific MQTT topic (devices//messages/events). Where device_id is the name of my broker, let's say 'mymqttbroker' just for fun.
So, what I'm trying to do is to take the messages that some in on pretty much any topic, and resend those messages through the bridge on the devices/mymqttbroker/messages/events topic to IoT Edge.
I know the topic line in the bridge config has the remote_prefix and local_prefix parameters, but that won't cut it. Per this article, it says you can't do this..
"E.g A broker would receive messages to topic sensor1 and remap them to new_sensor1. Currently this form of remapping is not available,"
Any idea how to do something like this? is it possible? Essentially, is there any way in the bridge to accept messages from any topic, and republish them on a specific fixed topic?
