problem about disconnecting device by BTstack

[mikew]

Hi，

I want to check if current code supports to free hci connection memory automatically when disconnecting by BTstack.

I use "a2dp_source_disconnect" and "hid_host_disconnect" to test and find the memory can not be freed autoly,  which will possibly cause memory leak. On the other hand, disconnecting by device will trigger hci connection memory free in BTstack.

Is there hasn't been considered before, or is the code designed that way?

Best wishes,

Mike

The function to trigger is "hci_shutdown_connection" in hid (br/edr), and there is more in audio device.

Hi Mike

Both a2dp_source_disconnect and hid_host_disconnect disconnect the specified profile, but keep the HCI connection alive in case for up to 10 seconds in case you want to switch to other services.
if you just want to disconnect a remote device, you can call "gap_disconnect".

Best
Matthias
