Firstly I am a complete newbie to node.js but I can do electronics. I have my Tessel 2 up and running and can run all the getting started guide (blinking etc. and will get the web-server up and running tomorrow)
I need to use a 3g/4g dongle with the Tessel 2. I have a Huawei model that powers up and appears to connect to the network fine.
I have an application where I want to communicate on both ethernet (to a local piece of equipment) and then report information to the cloud (over the 3G dongle).
How can I check if that the USB 3G dongle is working on the Tessel2? I can make an HTTP request from the tessel js code and see what i get back but how do I specify that I want the request to use teh 3G interface and not the USB/LAN connections?
