The M2X Interface
PC & SK2 environment setup
Running Quick Start
Overview I have been recently revisiting the software that goes along with the AT&T IoT Starter Kit (referred to as the SK2 for Starter Kit 2) and wanted to highlight for the community some of the capabilities and features this kit included. It really is a feature packed kit including: A Global Cat-4 modem module An Ambient Light Sensor Temperature Sensor 3-axis Acceler ...
I recently was asked to create an Azure IoT Client using the Mbed OS. I know that the ARM Mbed OS is a rapidly evolving operating system, so I thought that the first thing to do was to see if there was any reference/sample code available. After a lot of searching, I ended up on the Microsoft Azure IoT SDK github page. There is an Mbed OS reference design there but it is based on the earlier Mbed OS v2.0 and the current version is Mbed OS v5.9—and there is a ...
Ethernet with the NXP FRDM-K64F Board
LTE-M Cellular Data with a NXP FRDM-K64F
Now, you have a program that works using a cellular connection, but the beauty of ARM Mbed OS, is that once that is done, it is trivial to switch it to other transport methods. For example, when I was starting to work on this project, I implemented it using an NXP K64F board with its integrated Ethernet interface. This allowed me to get all the mechanics of building the SDK, the OS, and integra ...
How many times have you had to implement a button press/release routine (with de-bounce) for a project? If you write software for embedded projects, I’ll bet it is more than once. Because I was tired of writing this code over and over (well let’s be honest, I was copying it), I decided to write a button class that would be self-contained. I work with the ARM Mbed-OS a lot so I utilized some of the O/S services—primarily the EventQueue. I suppose wi ...

There are several MQTT solutions available for many different platforms and languages, and when you go looking for a ready-made solution to use, you may end up at https://github.com/mqtt/mqtt.github.io/wiki/libraries which provides several solutions and a lot of history. The solution I wanted would be implemented in C++ and storage would be allocated during object creation as opposed to me separately defining it. Because I was going to use the Mbed OS I decided to use https://os.mbed.com ...
That is an good question, I am a Bee Keeper so I though it appropriate to use a "busy bee" as my avatar. I started with 2 hives and grew it to 5 before this last winter when the weather managed to kill them all here in NC. Now I'm back to starting with 1 hive and hopefully the weather will cooperate. I really can't complain, I was able to keep the last ones going for 3 years. I suspect they would have been find over this past winter but the weather got warm, I suspect the ...
