Features

Usage

Example (Get Raw Value from Daydream Controller)

About Daydream Controller

1. Get CoreBluetoothManager instance

manager = CoreBluetoothManager.Shared;

2. Start Scan On PowerOn

manager.OnUpdateState((string state) =>
{
 Debug.Log("state: " + state);
 if (state != "poweredOn") return;
 manager.StartScan();
});

3. Discover And Connect Daydream Controller

manager.OnDiscoverPeripheral((CoreBluetoothPeripheral peripheral) =>
{
 if (peripheral.name != "")
 Debug.Log("discover peripheral name: " + peripheral.name);
 if (peripheral.name != "Daydream controller") return;
 manager.StopScan();
 manager.ConnectToPeripheral(peripheral);
});

4. Discover Services And Characteristic On Connected

manager.OnConnectPeripheral((CoreBluetoothPeripheral peripheral) =>
{
 Debug.Log("connected peripheral name: " + peripheral.name);
 peripheral.discoverServices();
});
manager.OnDiscoverService((CoreBluetoothService service) =>
{
 Debug.Log("discover service uuid: " + service.uuid);
 if (service.uuid != "FE55") return;
 service.discoverCharacteristics();
});

5. Enable Notify

manager.OnDiscoverCharacteristic((CoreBluetoothCharacteristic characteristic) =>
{
 string uuid = characteristic.uuid;
 string usage = characteristic.propertis[0];
 Debug.Log("discover characteristic uuid: " + uuid + ", usage: " + usage);
 if (usage != "notify") return;
 characteristic.setNotifyValue(true);
});

6. Handle Notify Value

manager.OnUpdateValue((CoreBluetoothCharacteristic characteristic, byte[] data) =>
{
 this.value = data;
 this.flag = true;
});

7. Start CoreBluetoothManager

manager.Start();

8. Write Value

byte[] value = { 0x64, 0x68 };
characteristic.Write(value);
