BLE4.0

#BLE 4.0 with iphone4s beason

看起来读取一个属性就是读取一个udid-最终的

-(void) readBattery:(CBPeripheral *)p {
    [self readValue:TI_KEYFOB_BATT_SERVICE_UUID characteristicUUID:TI_KEYFOB_LEVEL_SERVICE_UUID p:p];
}
 
 #define TI_KEYFOB_BATT_SERVICE_UUID                         0x180F
 
-(void) readValue: (int)serviceUUID characteristicUUID:(int)characteristicUUID p:(CBPeripheral *)p {
    UInt16 s = [self swap:serviceUUID];
    UInt16 c = [self swap:characteristicUUID];
    NSData *sd = [[NSData alloc] initWithBytes:(char *)&s length:2];
    NSData *cd = [[NSData alloc] initWithBytes:(char *)&c length:2];
    CBUUID *su = [CBUUID UUIDWithData:sd];
    CBUUID *cu = [CBUUID UUIDWithData:cd];
    CBService *service = [self findServiceFromUUID:su p:p];
    if (!service) {
        printf("Could not find service with UUID %s on peripheral with UUID %s\r\n",[self CBUUIDToString:su],[self UUIDToString:p.UUID]);
        return;
    }
    CBCharacteristic *characteristic = [self findCharacteristicFromUUID:cu service:service];
    if (!characteristic) {
        printf("Could not find characteristic with UUID %s on service with UUID %s on peripheral with UUID %s\r\n",[self CBUUIDToString:cu],[self CBUUIDToString:su],[self UUIDToString:p.UUID]);
        return;
    }  
    [p readValueForCharacteristic:characteristic];
}
