«LE Link отключен для дескриптора» «причина 708», когда приложение выполняет роль периферийного устройства

Мое приложение использует corebluetooth и играет 2 роли:

  1. Центральная роль: подключение к периферийному устройству (устройство IoT) для сбора данных (3 выборки в секунду).

  2. Роль периферийных устройств: реклама и уведомление данных с помощью предварительно определенной характеристики.

Мое приложение получало данные из IoT 3 раза в секунду, каждый раз, когда оно получало новые данные, оноотправить данные через предопределенную характеристику 

- (BOOL)updateValue:(NSData *)value forCharacteristic:(CBMutableCharacteristic *)characteristic onSubscribedCentrals:(nullable NSArray *)centrals;

Проблема в том, что если к моему приложению подключено более одного приложения для получения данных (эти приложения используют corebluetooth и играют центральные роли), то мое приложение получилоочень часто отключается от устройства IoT (каждые 5–10 минут).

В этом тестовом сценарии к моему приложению подключаются 3 приложения для получения данных через уведомление.

Тестовые устройства: iPad 6-го поколения 12.2, играет центральную роль при подключении к устройству IoT и играет периферийную роль при подключении к 3 другим приложениям.

Другие приложения работают на iPad 12.2,iPhone 5S iOS 11, iPad Air 12.2

Каждую секунду я видел столько журналов отправки данных в каждое приложение, почему corebluetooth использует слишком много связи через сообщения XPC?

Проблема послекаждые 5-10 минут я видел это сообщение: 

default 16:31:50.984625 -0600 bluetoothd LE Link disconnected for handle 0x106a018b0 address Public A0:E6:F8:28:DF:8D with reason 708

Мое приложение получило ответный вызов didDisconnectedPeripheral от corebluetooth для устройства IoT: 

default 16:31:51.032169 -0600 MyBLEApp Disconnected peripheral <CBPeripheral: 0x282f64aa0, identifier = 37DE887F-674B-E861-3192-B29C7F31D3D9, name = IOTDEVICE, state = disconnected> (error: Error Domain=CBErrorDomain Code=6 "The connection has timed out unexpectedly." UserInfo={NSLocalizedDescription=The connection has timed out unexpectedly.})

Почему corebluetooth не может сохранить соединение с IoTустройство?Это из-за того, что мое приложение играет периферийные роли, и могут ли другие приложения подключаться к нему?

Если я убью все другие приложения (центральная роль), после этого устройство IoT останется подключенным очень стабильно, и iPad, которыйиграет второстепенную роль, все еще занимаясь рекламой, когда она получает данные из Интернета вещей без каких-либо проблем.Спасибо.
