LibBluetooth

A cross platform Bluetooth library. The goal is to have a simple library that implements the functionality required for the most common Bluetooth uses cases, i.e. reading from a heart rate monitor, or similar device.

Initial focus is on Bluetooth LE devices, but more general Bluetooth support may be added in the future.

Supported Platforms

• macOS (Objective-C and Swift) - Successfully tested with a heart rate monitor, cycling power meter, cycling cadence sensor, and cycling radar.
• iOS (Objective-C and Swift) - Successfully tested with a heart rate monitor, cycling power meter, cycling cadence sensor, and cycling radar.
• Windows (C/C++) - Currently in-progress
• Android (planned)

Interface

The interface basically consists of just two methods: start and stop, with feedback being provided via callback functions.

mac OS and iOS

Objective C

- (void)start:(NSArray*)serviceIdsToScanFor
    withPeripheralCallback:(peripheralDiscoveredCb)peripheralCallback
    withServiceCallback:(serviceEnumeratedCb)serviceCallback
    withValueUpdatedCallback:(valueUpdatedCb)valueUpdatedCallback;
- (void)stop;

Swift

func startScanningForServices(serviceIdsToScanFor: Array<CBUUID>,
	peripheralDiscoveredCallbacks: Array<(CBPeripheral, String) -> Bool>,
	serviceCallbacks: Array<(CBPeripheral, CBUUID) -> Void>,
	valueUpdatedCallbacks: Array<(CBPeripheral, CBUUID, Data) -> Void>,
	peripheralDisconnectedCallbacks: Array<(CBPeripheral) -> Void>) 
func stopScanning()

Windows

In progress

C++

void start(const std::vector<GUID>& serviceIdsToScanFor,
	peripheralDiscoveredCb peripheralCallback,
	serviceEnumeratedCb serviceCallback,
	valueUpdatedCb valueUpdatedCallback);
void wait();
void stop();

Android
