BBC MICROBIT
Abstract:
Default 'out of the box' profile for the BBC Micro Bit
Summary:
Version 1.6 - 17th October 2015
Removed the Battery Service. No way to establish battery levels on the micro:bit
Added a simple Temperature Service to exploit temperature sensors in micro:bit processors with Temperature and Temperature Period characteristics.
Accelerometer and Magnetometer period characteristics now have uint16 fields instead of uint8 which required scaling up by multipling by 10.
Accelerometer Data and Magnetometer Data characteristics now use signed 16 bit integer fields for each of their X, Y and Z parts.
Accelerometer Data and Magnetometer Data characteristics now use signed 16 bit integer fields for each of their X, Y and Z parts.
New characteristic Magnetometer Heading added to the Magnetometer Service. Provides current heading in degrees.
Removed IO Parallel Port characteristic due to complexity and memory considerations.
Added Generic Attribute Service (previously absent in the repository)
Changed the LED Matrix State characteristic field so that we now have one octet per row of LEDs for ease of use.

Version 1.5 - 10th September 2015
Button State 2 characteristic given new, distinct UUID of E95DDA91-251D-470A-A062-FA1922DFA9A8
Removed the System LED State characteristic from the LED Service since it cannot be controlled from the BLE MCU.
Removed the Scrolling State characteristic from the LED Service due to complexity and memory constraints.
Changed LED Matrix State use of “Write Without Response” to “Write” so that no further writes can be made until there’s been an ACK back from the previous one.
Removed Write property from MicroBit Requirements characteristic.
