ios – Corebluetooth在連接后斷開連接

我得iPhone充當中央,我得iPad充當外圍設備.

我正在宣傳我得服務但在我得中心時,我正在通過：

peripheral:didDiscoverServices:

我在該方法中獲得得peripheral.services是空得.

我錯誤地從外設斷開后幾秒鐘：

DISCONNECT-ERROR desc : Error Domain=CBErrorDomain Code=7 "The specified device has disconnected from us." UserInfo=0x16e60f90 {NSLocalizedDescription=The specified device has disconnected from us.}

我不知道發生了什么事.

編輯：

在中央方面我有這個：

-(void)startScanning{    [super startScanning];    // Scan for devices    [self.centralManager scanForPeripheralsWithServices:@[[CBUUID UUIDWithString:PERIPHERAL_SERVICE_UUID]] options:nil];}#pragma mark Peripheral Delegate- (void)peripheral:(CBPeripheral *)peripheral didDiscoverServices:(NSError *)error {    if (error) {        [self cleanup];        return;    }    for (CBService *service in peripheral.services) {        [peripheral discoverCharacteristics:@[[CBUUID UUIDWithString:NEW_COMMANDS_NOTIFIER_CHARACTERISTICS_UUID]] forService:service];    }    // Discover other characteristics}- (void)peripheral:(CBPeripheral *)peripheral didDiscoverCharacteristicsForService:(CBService *)service error:(NSError *)error {    if (error) {        [self cleanup];        return;    }    for (CBCharacteristic *characteristic in service.characteristics) {        if (self.commandsFromIpadCharacteristic != characteristic) {            self.commandsFromIpadCharacteristic = characteristic;        }        if ([characteristic.UUID isEqual:[CBUUID UUIDWithString:NEW_COMMANDS_NOTIFIER_CHARACTERISTICS_UUID]]) {            [peripheral setNotifyValue:YES forCharacteristic:characteristic];        }    }}

在外圍方面,我有：

#pragma mark CBPeripheralManagerDelegate- (void)peripheralManagerDidUpdateState:(CBPeripheralManager *)peripheral{    if (peripheral.state != CBPeripheralManagerStatePoweredOn) {        return;    }    if (peripheral.state == CBPeripheralManagerStatePoweredOn) {        self.datasFromIphoneCharacteristic = [[CBMutableCharacteristic alloc] initWithType:[CBUUID UUIDWithString:NEW_DATAS_FROM_IPHONE_CHARACTERISTICS_UUID] properties:CBCharacteristicPropertyWrite value:nil permissions:CBAttributePermissionsWriteable];        self.commandNotifierCharacteristic = [[CBMutableCharacteristic alloc] initWithType:[CBUUID UUIDWithString:NEW_COMMANDS_NOTIFIER_CHARACTERISTICS_UUID] properties:CBCharacteristicPropertyNotify value:nil permissions:CBAttributePermissionsReadable];        CBMutableService *transferService = [[CBMutableService alloc] initWithType:[CBUUID UUIDWithString:PERIPHERAL_SERVICE_UUID] primary:YES];        transferService.characteristics = @[self.datasFromIphoneCharacteristic,self.commandNotifierCharacteristic];        [self.peripheralManager addService:transferService];        [self.peripheralManager startAdvertising:@{CBAdvertisementDataServiceUUIDsKey : @[[CBUUID UUIDWithString:PERIPHERAL_SERVICE_UUID]]}];    }}- (void)peripheralManagerDidStartAdvertising:(CBPeripheralManager *)peripheral error:(NSError *)error {    if (error) {        NSLog(@"Error advertising: %@",[error localizedDescription]);    }}- (void)peripheralManager:(CBPeripheralManager *)peripheral central:(CBCentral *)central didSubscribeToCharacteristic:(CBCharacteristic *)characteristic {    if (characteristic == self.commandNotifierCharacteristic){        // on envoie le message au delegate        if([[self delegate] respondsToSelector:@selector(iPhoneIsConnectedToIpad:)]) {            [[self delegate] iPhoneIsConnectedToIpad:YES];        }    }}-(void)peripheralManager:(CBPeripheralManager *)peripheral central:(CBCentral *)central didUnsubscribeFromCharacteristic:(CBCharacteristic *)characteristic{    if (characteristic == self.commandNotifierCharacteristic){        // on envoie le message au delegate        if([[self delegate] respondsToSelector:@selector(iPhoneIsConnectedToIpad:)]) {            [[self delegate] iPhoneIsConnectedToIpad:NO];        }    }}

編輯答案：

我發現了問題,在centralManager中：didConnectPeripheral：我沒有使用[peripheral discoverServices：]調用正確得服務UUID.謝謝您得幫助 ：).
