Bluetooth LE Devices

This topic describes the technology to create a peer-to-peer connection between a Bluetooth or Bluetooth Low Energy (LE) device and a mobile phone.

Preparation

• System requirements: Bluetooth connectivity requires Android 4.3 and later, and the Smart Life App SDK supports Android 4.4 and later.
• Manifest permissions:

  <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
  <uses-permission android:name="android.permission.BLUETOOTH" />
  <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
  

• Precheck of Bluetooth permissions: This percheck is essential. Otherwise, the app cannot use Bluetooth connectivity as expected.
  • Check whether the location permissions are enabled for an app before it uses Bluetooth connectivity or starts scanning.
  • Check whether the Bluetooth feature is enabled.
    This precheck is not provided by the Smart Life App SDK. You can manually perform the precheck.

Scan for Bluetooth devices

Parameters

Parameter	Type	Description
setting	LeScanSetting	The setting of the scanning feature.
response	TyBleScanResponse	The callback of the scanning result. It cannot be empty.

Builder class

LeScanSetting.Builder is used to build the settings for device scanning.

Method name	Type	Description	Required
setTimeout()	long	The timeout value of a pairing task. Default value: 40000. Unit: milliseconds.	No
addScanType()	ScanType	SINGLE: scan for Bluetooth LE devices MESH: scan for Tuya mesh devices SIG_MESH: scan for Bluetooth mesh devices SINGLE_QR: scan a QR code for pairing	Yes
setRepeatFilter()	Boolean	Specifies whether a repeat filter is enabled. Default value: true.	No

Example

LeScanSetting scanSetting = new LeScanSetting.Builder()
		.setTimeout(60000) // The duration of the scanning. Unit: milliseconds.
		.addScanType(ScanType.SINGLE) // `ScanType.SINGLE`: scans for Bluetooth LE devices.
		// `.addScanType(ScanType.SIG_MESH)`: scans for other types of devices.
		.build();

// Starts scanning.
TuyaHomeSdk.getBleOperator().startLeScan(scanSetting, new TyBleScanResponse() {
	@Override
	public void onResult(ScanDeviceBean bean) {
		// The callback of the scanning result.
	}
});

Pair over Bluetooth due to unavailable Wi-Fi

Certain combo devices support pairing over Bluetooth if Wi-Fi connections are unavailable. Certain Wi-Fi and Bluetooth combo devices support pairing over Bluetooth if a Wi-Fi connection is unavailable. App users trigger cloud-based activation and required data is sent to a target device over Bluetooth. Then, the device attempts to connect to the target Wi-Fi network. If the device failed to be activated in the cloud, Bluetooth connections will be created between the device and the app on the mobile phone.

Activate locally-connected combo device in cloud

A combo device is locally connected to the app over Bluetooth after it failed to connect to the Wi-Fi network. The following method helps you attempt to activate this device in the cloud through a Wi-Fi channel. In this call, the target device must be paired with the app over Bluetooth and cloud-based activation failed.

1. You can call getCommunicationOnline(CommunicationEnum.BLE) of DeviceBean to check the Bluetooth connection status.

2. To check whether a device is activated in the cloud, call deviceBean.getMeta().get("wifiEnable") and get the Wi-Fi connection status.

    @Override
    public void onSuccess(DeviceBean deviceBean) {
        // Activated successfully
    }
    @Override
    public void onFailure(int code, String error, Object handle) {
        // Activation fails
    }
};

// Use bluetooth to activate
TuyaHomeSdk.getActivator().newMultiModeActivator().startBleActivator(multiModeActivatorBean, listener);

Operate Bluetooth devices

This section describes how to operate a paired Bluetooth LE device. For example, check the device status, connect to the device, or unbind it.

Check online status of a device

• Method 1: returns the online status by using the same method as that for a Wi-Fi device. If the Bluetooth device is added to a gateway, the device can stay online in the cloud.

  TuyaHomeSdk.getDataInstance().getDeviceBean(devId).getIsOnline();
  

• Method 2: checks whether a device is locally connected over Bluetooth. In most cases of a Bluetooth device, you can care about only the local connection status. If the Bluetooth device is added to a Bluetooth gateway, the device status in the cloud must be checked.

  TuyaHomeSdk.getBleManager().isBleLocalOnline(devId);
  

Connect to an offline device

API description

void connectBleDevice(List<BleConnectBuilder> builderList);

Parameters

Parameter	Type	Description
builderList	List	A collection of BleConnectBuilder that is used to build the settings for device connections.

Description of BleConnectBuilder

Method name	Parameter	Description
setDirectConnect()	Boolean	true: uses a cached connection to accelerate the process. false: does not use a cached connection.
setDevId()	String	The value of devId for the target device.
setScanTimeout()	Integer	The timeout value for scanning. Unit: milliseconds.
setLevel()	BleConnectBuilder.Level	NORMAL: If connection resources have reached the upper limit, the current connection is ignored. FORCE: If connection resources have reached the upper limit, other resources are released to enable the current connection. Default value: NORMAL

Example

List<BleConnectBuilder> builderList = new ArrayList<>();

BleConnectBuilder bleConnectBuilder1 = new BleConnectBuilder();
BleConnectBuilder bleConnectBuilder2 = new BleConnectBuilder();

bleConnectBuilder1.setDevId(devId1); // The value of `devId` for Device 1.
bleConnectBuilder2.setDevId(devId2); // The value of `devId` for Device 2.

builderList.add(bleConnectBuilder1); // Adds Device 1.
builderList.add(bleConnectBuilder2); // Adds Device 2.

TuyaHomeSdk.getBleManager().connectBleDevice(builderList); // Starts the connection task.

Disconnect a device

API description

void disconnectBleDevice(List<BleConnectBuilder> builderList);

Parameters

Parameter	Type	Description
builderList	List	BleConnectBuilder is used to build the settings for device disconnections.

Description of BleConnectBuilder

Method name	Parameter	Description
setDevId()	String	The value of devId for the target device.

Example

TuyaHomeSdk.getBleManager().disconnectBleDevice(builderList); // Starts the disconnection task.

Operate devices

Listens for device status by using the device operation class. Similar API methods as Wi-Fi devices are called. For more information, see Device Management. The following operations are supported:

• Query device information

• Initialize device control

• Register a device listener

• Unregister a device listener

• Data points of devices

• Rename a devices

• Remove a device

  Similar to a Wi-Fi device, to unbind a Bluetooth device, call TuyaHomeSdk.newDeviceInstance("devId").removeDevice() or resetFactory(). However, the following differences must be noted:

  • The target Bluetooth device will be removed from the cloud and locally connected device list. If the device is offline, it is only removed from the cloud and is still bound with the app.
  • To bind a device again after the unbinding operation, the device must be manually set to the state to be paired.
  • During device scanning, if the SDK discovers the device in the bound state but disconnected from the cloud, the device will be automatically reset.

• Recycle device resources

Firmware update

Firmware information must be checked before the over-the-air (OTA) update.
