I am looking for a simple "Hello World" code for the MIlli kit. Does any one have one and will this work on Arduino Uno?
The Milli "Hello World" reference app is a temperature sensor that integrates with the Adafruit Metro Express M0 board. Previously we used the Arduino M0 Pro board; both are pin compatible with the Itron Millishield board, and use 32-bit ARM processors. With the Adafruit board, we provide an easy way to load the reference application using a UF2 bootloader image. This image can be found at the Itron GitHub repository under the Release folder. The image includes Itron's reference COAP Server; the C++ code for the COAP server can also be found in the Itron GitHub repository.
Instructions for setting up the reference application with a temperature sensor and Adafruit Metro M0 Express board can be found here. An easy-to-install DHT11 temperature sensor for the reference application can be purchased on Amazon.com at this link.
For a low power application, the Arduino Uno is a possibility, but that requires loading the proper libraries onto the board, and recompiling the COAP server for the Uno's 8-bit ATmega328p microcontroller.
