  • 标签:iOS 例子 开发

1建立中心角色

class="brush:objc;gutter:true;">#import <CoreBluetooth/CoreBluetooth.h>  
CBCentralManager *manager;  
manager = [[CBCentralManager alloc] initWithDelegate:self queue:nil];  

2扫描外设(discover)

[manager scanForPeripheralsWithServices:nil options:options]; 

3连接外设(connect)

- (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI  
{
        if([peripheral.name  isEqualToString:BLE_SERVICE_NAME]){
                [self connect:peripheral];
        }
s);  
}        

-(BOOL)connect:(CBPeripheral *)peripheral{
        self.manager.delegate = self;
        [self.manager connectPeripheral:peripheral
                                options:[NSDictionary dictionaryWithObject:[NSNumber numberWithBool:YES] forKey:CBConnectPeripheralOptionNotifyOnDisconnectionKey]];
}

  

4扫描外设中的服务和特征(discover)

- (void)centralManager:(CBCentralManager *)central didConnectPeripheral:(CBPeripheral *)peripheral  
{  
      
    NSLog(@"Did connect to peripheral: %@", peripheral);  
    _testPeripheral = peripheral;  
      
    [peripheral setDelegate:self];  
//查找服务 [peripheral discoverServices:nil]; }
- (void)peripheral:(CBPeripheral *)peripheral didDiscoverServices:(NSError *)error  
{  
  
      
    NSLog(@"didDiscoverServices");  
      
    if (error)  
    {  
        NSLog(@"Discovered services for %@ with error: %@", peripheral.name, [error localizedDescription]);  
          
        if ([self.delegate respondsToSelector:@selector(DidNotifyFailConnectService:withPeripheral:error:)])  
            [self.delegate DidNotifyFailConnectService:nil withPeripheral:nil error:nil];  
          
        return;  
    }  
      
  
    for (CBService *service in peripheral.services)  
    {  
         //发现服务
        if ([service.UUID isEqual:[CBUUID UUIDWithString:UUIDSTR_ISSC_PROPRIETARY_SERVICE]])  
        {  
            NSLog(@"Service found with UUID: %@", service.UUID);  
//查找特征 [peripheral discoverCharacteristics:nil forService:service]; break; } } }
- (void)peripheral:(CBPeripheral *)peripheral didDiscoverCharacteristicsForService:(CBService *)service error:(NSError *)error
{
    
    if (error)
    {
        NSLog(@"Discovered characteristics for %@ with error: %@", service.UUID, [error localizedDescription]);
        
        [self error];
        return;
    }
    
    NSLog(@"服务:%@",service.UUID);
    for (CBCharacteristic *characteristic in service.characteristics)
    {
       //发现特征
            if ([characteristic.UUID isEqual:[CBUUID UUIDWithString:@"xxxxxxx"]]) {
                NSLog(@"监听:%@",characteristic);
//监听特征 [self.peripheral setNotifyValue:YES forCharacteristic:characteristic]; } } }

5与外设做数据交互(读 与 写)  

- (void)peripheral:(CBPeripheral *)peripheral didUpdateValueForCharacteristic:(CBCharacteristic *)characteristic error:(NSError *)error
{
    if (error)
    {
        NSLog(@"Error updating value for characteristic %@ error: %@", characteristic.UUID, [error localizedDescription]);
        self.error_b = BluetoothError_System;
        [self error];
        return;
    }
    
//    NSLog(@"收到的数据:%@",characteristic.value);
    [self decodeData:characteristic.value];
}

NSData *d2 = [[PBABluetoothDecode sharedManager] HexStringToNSData:@"0x02"];
                [self.peripheral writeValue:d2 forCharacteristic:characteristic type:CBCharacteristicWriteWithoutResponse];
