Glad you asked:

1. Build mpy-cross on your computer:

   git clone <https://github.com/micropython/micropython.git>
   cd micropython
   cd mpy-cross
   make
   

2. Put the folder with your code inside the build folder

3. Use mpy-cross to generate .mpy’s from .py files like this:

   cd build
   mpy-cross PyLora_SX127x_extensions/pyLora.py
   

   • Here is a way to do all the .py files inside the folder at once:

4. Use ampy to “put” .mpy files into the micropython device

ampy --port /dev/tty.usbserial-0001 ls #To check the files
ampy --port /dev/tty.usbserial-0001 put PyLora_SX127x_extensions/pyLora.mpy PyLora_SX127x_extensions/pyLora.mpy # To place pyLora.mpy in folder inside device
