Updates to BLE interface to match specification following testing by Bluetooth SIG.
Accelerometer Period: now supports READ and WRITE
Magnetometer Period: now supports READ and WRITE
LED Matrix State: now supports READ and WRITE.
UUIDs of Temperature Service characteristic corrected.
First functionally complete BLE profile, matching BLE speicfication v1.6.
More specifically, the following services are now functional:
- AccelerometerService
- MeganetometerService
- EventService
- TemperatureServide
- IOPinService
- DFUService
- ButtonService
- LEDService
Also, updates to underlying device drivers to enable greater configurability:
- MicroBitCompass now supports variable sample rates and temperature sensing
- MicroBitAccelerometer now supports variable sample rates and ranges
- MicroBitThermometer introduced
- MicroBitMessageBus adapted to permit enumeration and block removal of listeners
Finally, MicroBit DFU Service has been changed to the new UUIDs specificed in v1.6 of BLE spec.
