Alright, in that case I totally need to change my setup. I'm working on a project in which we are trying to fly a large kite using built in steering. For this we've set up a network connection with the kite to send and receive messages. For example: we measure altitude, direction, speed, etc. and we need to send that info back down to earth. All this happens in separate messages, because they are collected asynchronously.
Does this mean that we need to setup a separate socket and connection in zeromq for every type of message we want to send down to earth? Also I wanted to make a logger process to which all messages should be send in order to write them to the central log file. This would make it impossible because messages that are collected can be any of the different (.proto) types. Is there no option to send an identifier with the message so that the type can be recognized? Or would a better solution be to create one universal message with all types set to optional (which would create a lot more overhead I guess)?
