Edge device with information prioritisation / managing the socket messages

Hello,

I have to send some alarms, warnings and errors from a device (microcontroleur) to thingworx. The SDK type has not been choosen yet, but I would personnaly prefer the Java SDK. Because the quality of the network is very poor, I have to prioritize the message sending. It means that I have to make sure that the errors will be send first.

- Is that possible using the SDK?

- or should I manage myself a queue of messages ?

- How can I make sure that a value has been successfully sended / received using updateSubscribedProperties?

Can I also switch the network used if one is down, for instance switching from Wifi to GSM? In java I would open a socket for a given interface, is that also possible? 

socket.bind(ni.getInetAddresses().nextElement());
