I can't seem to find someone explaining what I have to do exactly in order to be able to make my code compile the very first line from network import LoRa.
I browsed through this network.py and it doesn't even mention LoRa (nor lora actually), I watched the micro python doc without any success.
I read somewhere I need to install upip but I'm not so sure what I'm doing wrong, noone seem to have trouble with the imports.
My Raspberry 3 successfully detect my PyCom device in USB.
You need to connect to the device first through the USB serial port.
The module comes with its own Python interpreter / REPL which is running on the embedded MCU.
I suggest you look at https://docs.pycom.io/gettingstarted/ and also post on https://forum.pycom.io if you have more detailed questions.
