Bledroid BLE Init/Deinit memory leak issue
Posted: Sun Aug 21, 2022 6:58 am
Hi All,
In my application, I am periodically enabling / disabling ble (bluedroid). I have noticed that with each init / denit cycle, almost 700 bytes of heap memory is leaking. I did find serveral posts regarding this issue on the forum and on the net, but no conclusive solution.
All I am doing in these cycles is initializing ble, running a scan and then denintializing ble
