Bluetooth Device Pairing

Bluetooth device search and pairing applies to Bluetooth Low Energy (LE), Bluetooth mesh, combo device, and beacon.

Bluetooth type	Description	Example
Bluetooth LE	A point-to-point connection is created between a Bluetooth or Bluetooth LE device and a mobile phone.	Body fat scales, wrist-worn trackers, thermostats, electric toothbrushes, and smart locks
Bluetooth mesh	Enable many-to-many (m:m) device communications over a mesh network released by Bluetooth SIG.	Cool white lights (C), cool and warm white lights (CW), white and colored lights (RGBCW), sockets, sensors, and other sub-devices
Combo devices	Devices that support both Bluetooth and other protocols, such as Wi-Fi and Bluetooth LE combo, can be paired over Bluetooth.	Bluetooth mesh gateways, IP cameras (IPCs), and Wi-Fi and Bluetooth combo devices
Beacon	Beacon is a broadcast protocol built on top of Bluetooth LE.	Lights, fans, remotes, and body fat scales

Pairing process

Register the pairing type

When the device pairing service is initialized, register the pairing type.

Device type	Pairing type	Model
Bluetooth LE or combo device	ThingSmartActivatorTypeBle	ThingSmartActivatorTypeBleModel
Bluetooth mesh	ThingSmartActivatorTypeSigMesh	ThingSmartActivatorTypeSigMeshModel
Beacon	ThingSmartActivatorTypeBeacon	ThingSmartActivatorTypeBeaconModel

/// Initialize network configuration types
/// @param typeList Network configuration types
- (void)registerWithActivatorList:(NSArray<ThingSmartActivatorTypeModel *>*)typeList;

Parameter description

Parameters	Description
typeList	The list of pairing types.

Get a token

The SDK gets a pairing token from the cloud before it can start the pairing process. The token is valid for 10 minutes and expires immediately after the device is paired. A new token must be generated if the device needs to be paired again.

API description

- (void)getTokenWithHomeId:(long long)homeId
                   success:(ThingSuccessString)success
                   failure:(ThingFailureError)failure;

Parameter description

Parameters	Description
homeId	The ID of the home with which the device is bound.
success	The success callback. A pairing token is returned.
failure	The failure callback. An error message is returned.

Start searching

Pass in the registered typeList to start searching.

API description
