Is it possible to connect to two MQTT brokers at the same time with this library? #40

From a friend i got an ESP sketch to get P1 readings form an powermeter and send them to an Mosquitto MQTT broker.

It works well.

I try to change the sketch so i can connect to two Mosquitto MQTT brokers at the same time, but I endup in a connection loop when using the client1.loop(); and client2.loop() statements.

Does this library support using two clients simultaniously?

Well it's not been tested doing that. But everything is nicely encapsulated and there are no global variables, so it shouldn't be a problem.

How are you calling client1.loop() and client2.loop(), and just what is this "connection loop"?

edautz commented 8 years ago

After publish some data to the MQTT broker, the sketch calls client1.loop() or client2.loop().

While calling it, it generates lots of connections to the broker.

I can send the sketch if this helps.

As a work around, if you not aware, you can setup one of your brokers in bridge mode so that you can publish the information to the second broker. http://mosquitto.org/man/mosquitto-conf-5.html

I am aware of that solution, but I got two seperate MQTT brokers and two seperate homedomotica systems for redundancy and testing purposes. I want to keep my setup this way.
