About Daydream Controller

• Get raw value form Daydream controller

Property	Target
Peripheral Name	Daydream controller
Service UUID	FE55
Characteristic Usage	notify

1. Get CoreBluetoothManager instance

• Get shared 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 };
