Project: Pebble Display

My current project is an external display for the Pebble™ Environment Monitor.

The Pebble is a Bluetooth-based outdoor temperature/pressure/humidity sensor and the idea is that you can see the current values on an iOS or Android app.

Unfortunately, the device/app comminication is a bit too slow and it's really annoying to wait 10 or 20 seconds before the app gets a new reading from the device.

So I'm building a small device that comprises a Bluetooth SoC and a display. I'm using a Nordic Semiconductor nRF51822 as MCU and Bluetooth interface and some kind of e-paper display (because a) it looks cool, b) I haven't worked with e-paper displays before). This way I can have a nice wall-mounted display that always shows the last received temperature.

I'll be using Keil µVision 5 (free version) with Nordic nRF5 SDK 12 as development platform.

Further bulletins as events warrant…
