Golioth SDK for MicroPython

Adding support for building IoT devices using Golioth and Micropython.

• Samples
  • LightDB

Download and Install MicroPython (Work In Progress)

We forked MicroPython to add support for DTLS.

It's available on this fork/branch - https://github.com/goliothlabs/micropython/tree/add-dtls-psk-support

Follow the instructions to build for an esp32.

Install tools

$ pip3 install adafruit-ampy
$ pip3 install esptool

Find serial port

$ ls /dev/tty.*
# In my case was /dev/tty.SLAB_USBtoUART

Clean flash and send micropython binary

$ esptool.py --port /dev/tty.SLAB_USBtoUART erase_flash
$ esptool.py --chip esp32 --port /dev/tty.SLAB_USBtoUART --baud 460800 write_flash -z 0x1000 esp32.bin

Install Libraries

$ ampy --port /dev/tty.SLAB_USBtoUART put lib/microCoAPy/microcoapy

Copy Sample

$ ampy --port /dev/tty.SLAB_USBtoUART put samples/main.py main.py
