"Random" Disconnects (didDisconnectPeripheral) in iOS

[mamen2022]

Hi, I am developing a Flutter App for the past few months in Android and the Bluetooth is working correctly. Recently I began migrating to iOS and I keep getting "random" disconnects without any errors or crashes, besides this :

didDisconnectPeripheral

Does anyone know why this happens or experienced the same problem? I am testing with an iPhone 6 (iOS 12.1.4) and a ESP32 as ble central. Any ideas ?

In comparison to Android, the bluetooth scan and connect seems at least 10 times slower, but the communication (write/read) between devices seems fine.

Best Regards

Hi, I have also some different behaviours on flutter blue v0.5.0 between Android 8.0 (phone and tablet) and iOS 12.2 (iphone 5s, 8 and XR). My problems are in connection with ESP32 devices. The scan, connection and communication (R/W) works fine on 2 services/characteristics (similarly fast on both Android and iOS), but problems are on disconnecting. On iOS the disconnect is not signalled to the esp32 side, but on Android it is. I used deviceConnection.cancel(); (and also scanSubscription.cancel();), in an explicit button, but when triggered it doesn't disconnect on iOS. br

(later edit:) This was fixed, as there seems to be some issue in my esp32 firmware, plus some bugs in mobile app.

Could someone find or solve the problem? I also have these complete random disconnects.
