Over the course of this year I’ve worked on a wearable project that utilizes a Silicon Labs Blue Gecko BGM113. I’ve also spent a bunch of time playing with my Thunderboard React and Thunderboard Sense 2.

Along the way, I think I’ve picked up a few things. As an old bloke who’s been in this embedded software caper for more than a quarter of a century, I figure I might have something worthwhile to share. Also, I absolutely love this stuff. Hence I’m launching into a series of posts.

I’ll probably cover a collection of Thunderboard-specific topics. Such as:

• Over The Air (OTA) Upgrades
• Secure OTA
• CR2032 Battery Level Measurement
• Apple Bluetooth Guidelines Compliance
• Power Optimization
• React MPU6500 DMP & Step Counter
• Sense 2 ICM20648 DMP & Step Counter
• OpenOCD for flashing from a Raspberry Pi

I’ll probably lurch into a few other more general areas in which I’ll just use the Thunderboard as an example. Like:

• Automated Testing with Robot Framework & PyGatt
• Continuous Integration
• Unit Testing (on-host)
• Automated software versioning
• AWS IoT Core
• Google Cloud IoT

You can play along at home, or you can grab the code, as it evolves, from here:

• https://github.com/gregbreen/uncannier-thunderboard-react
• https://github.com/gregbreen/uncannier-thunderboard-sense2

Right then. Let’s start with Thunderboard React – Over The Air (OTA) Upgrades.
