While writing data in BLE device (file size is 459 KB), connection lost happened in between BLE device and application. It's happened particularly in iOS 14.7.1 devices not for older OS (like 14.6). I observe MTU size also different in iOS 14.4 and iOS 14.7.
When disconnection happened CoreBluetooth -> centralManager: didDisconnectPeripheral delegate method call.
Can't figure what's the main issue, 1) issue from BLE end 2) issue for application end 3) issue for OS end
Is any key value should I add in application. What is proper solution for resolve this issue.
