Minor changes to BLE profile services (cleanup prior to merge with master branch):
- Added temperature period characteristic to match design pattern of other sensors.
- Updated endinaness of MicroBitLEDService Matrix to be more intuitive.
- Cleaned up Microbit.cpp by removing unused reference to BLE services.
- Exposed serial number and naming information thr BLE DeviceInformation and API.
- Updated BLE advertisement period to be alightly more repsonsive (200ms vs 1000ms).
- BUGFIX: micro:bit name is now always generated, regardless of BLE services.
- BUGFIX: Scroll Period data length.
All message bus listeners with the micro:bit runtie are non blocking, and safe to be called
in an interrupt context. As such, these have now all been declared MESSAGE_BUS_LISTENER_IMMEDIATE
which should mitigate all unbounded event queueing effects.
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.
