Automatic Reconnection not available on Android 14 #440

Closed LucaOnesto closed 3 months ago

LucaOnesto commented 3 months ago

Hi,

in our mobile application we implemented the automatic reconnection to our devices, so that if a disconnection occurs (e.g. due to a reboot of the system), the system will automatically reconnect.

With the application running on Android 14, we noticed that if our device is not available for more than around 10 seconds, the following error occurs: 

onClientConnectionState() - status=133 clientIf=6 device=XX:XX:XX:XX:29:42

This does not happen with previous version of Android.

Tests were done with version 2.2.2 and 2.4.2 of lib-dfu.

Hi, But.. what does it have to do with the DFU library? The lib does not hold connection.

Error 133 after 10ish or 30 sec may mean a timeout. This usually happens when you try to reconnect with autoConnect = false when the device is not available. But with automatic reconnections there should be no timeout. I didn't try that on Android 14.

Hi philips77,

Thanks for your suggestion. I checked the latest version of the ble-library and it works also with Android 14.
