Transmitting mounds of data in realtime over Bluetooth Low Energy
Transmitting mounds of data in realtime over Bluetooth Low Energy

My client needed to receive a relatively large amount of data on a mobile device, from an embedded system, and process it in near-realtime.   The simplest method for communication with a whole host of mobile devices is to go over bluetooth low energy, but this protocol’s main concern is more about power conservation than throughput. …

NanoKeys Released

As promised, the NanoKeys library has been made public and is now available on it’s own project page! One noteworthy change is a modification to the key send/key clear algorithm that allows for much quicker transmission of key strokes and a snappier user experience.  Here’s a short clip of the new functionality in action: And…

Announcing NanoKeys: turning a BLE Nano into an HID Keyboard, the easy way
Announcing NanoKeys: turning a BLE Nano into an HID Keyboard, the easy way

I’m finishing up the docs for NanoKeys, a small BLE Nano (and probably any mbed BLE API supported devices) library that gives you an easy way to create a bluetooth low energy keyboard that you can pair with using any mobile device. The project page, code and documentation will be up shortly (in the projects…

BLE Nano: Review, Tips and Workarounds
BLE Nano: Review, Tips and Workarounds

I’ve recently had to develop an application using the BLE Nano platform. The BLE Nano is a little module built around the Nordic nRF51822 SoC, along with a minimalist set of support components  including an on-board antenna for the bluetooth wireless connection.  The Nordic itself provides all the Bluetooth low energy functionality and hosts your…

BLE112 In-system Programmer
BLE112 In-system Programmer

I do a lot of work with bluetooth low energy (BLE or bluetooth v4.0) and have a few different BLE modules I’ll turn to, but often end up using the Bluegiga BLE112 (as evidenced by my DIY BLE112 breakout).  It’s a great chip but one thing that can get annoying is programming the thing. Whether…
