The iOS SDK supports KN550LT in versions 2.14.0 and above.

WorkFlow​

  1. Scan and connect KN550LT blood pressure monitor.

  2. KN550LT supports online and offline measurement.

In the iOS SDK, use HealthDeviceType_KN550LT to scan for this device.

Connection to device​

1.Listen to device notify​

[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(deviceDiscovered:) name:KN550LTDiscover object:nil];

[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(deviceConnectFailed:) name:KN550LTConnectFailed object:nil];

[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(DeviceConnected:) name:KN550LTConnectNoti object:nil];

[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(DeviceDisconnected:) name:KN550LTDisConnectNoti object:nil];

[KN550LTController shareIHKN550LTController];

2.Scan for devices​

[[ScanDeviceController commandGetInstance] commandScanDeviceType:HealthDeviceType_KN550LT];

3.Connect to devices​

[[ConnectDeviceController commandGetInstance] commandContectDeviceWithDeviceType:HealthDeviceType_KN550LT andSerialNub:deviceMac];

4.Get the device instance​

KN550LT *device = [[KN550LTController shareIHKN550LTController] getInstanceWithMac:deviceMac];
