2、Frameworks
3、Configuration
Add 2 new Item in ‘Supported external accessory protocols’: com.jiuan.BPV20, com.jiuan.P930, com.jiuan.BPV21,com.jiuan.BGV30,com.jiuan.BGV31,com.ihealth.sc221 
Add 1 new Item in ‘Required background modes’: App communicates with an accessory、 App communicates using CoreBluetooth
1. Operation procedure for BP3.
```Reference BP5```
2. Operation procedure for BP5.
a) Register plug-in device info: `BP5ConnectNoti`;
b) Initialize controller classes:
```BP5Controller *controller = [BP5Controller
shareBP5Controller];```
c) Access control class instance after receive `BP5ConnectNoti`:
```NSArray *bpDeviceArray = [controller
getAllCurrentBP5Instace];```
``` BP5 *bpInstance = [bpDeviceArray objectAtIndex: i];```
d) Using ‘bpInstance’ call communication module of the device
3. Operation procedure for BP7.
```Reference BP5```
4. Operation procedure for ABI.
For ABI Mesure(both arm and leg)
a) Register plug-in device info: `ABIConnectNoti`;
b) Initializedcontrollerclass:
```ABIController *controller = [ABIController
shareABIController];```
c) Access controller class instance after receive `ABIConnectNoti`:
```ABI *bpInstance = [controller getCurrentABIInstace];```
d) Using ‘bpInstance’ call communication module of the device.
For Arm Mesure(arm only)
a) Register plug-in device info: `ArmConnectNoti`;
b) Initializedcontrollerclass:
```ABIController *controller = [ABIController
shareABIController];```
c) Access controller class instance after receive ArmConnectNoti:
```ABI *bpInstance = [controller getCurrentArmInstance];```
d) Using ‘bpInstance’ call communication module of the device.
5. Operation procedure for BP3L.
a) Register plug-in device info: `BP3LDiscover`;
b) Start scan BP3L
``` [[ScanDeviceController commandGetInstance]commandScanDeviceType:HealthDeviceType_BP3L] ```
c) Register plug-in device info: `BP3LConnectFailed`、`BP3LConnectNoti`、 `BP3LDisConnectNoti`;
d) Connect BP3L after receive `BP3LDiscover`
``` [[ScanDeviceController commandGetInstance]commandStopScanDeviceType:HealthDeviceType_BP3L] ```
``` [[ConnectDeviceController commandGetInstance]commandContectDeviceWithDeviceType:HealthDeviceType_BP3L andSerialNub:serialNub] ```
e) Access control class instance after receive `BP3LConnectNoti`:
```BP3LController *controller = [BP3LController
shareBP3LController];```
``` NSArray *bpDeviceArray = [controller
getAllCurrentBP3LInstace]; ```
```BP3L *bpInstance = [bpDeviceArray objectAtIndex: i];```
f) Using ‘bpInstance’ call communication module of the device
