BC127 Melody fails to close bluetooth connection


I am working on a BC127 with the 7.3 Melody firmware version on a2dp and avrcp profiles and I am facing to a an issue to close the BT connection.

Connect to devices, stream audio and control it works fine, but with some bluetooth earphones the a2dp refuse to close but the avrcp link close correctly. The only solution I found to work around this, is to reset the bc127 device.

To close all the connection I tried “unpair” , close all commands and even on each link
but still the a2dp link refuse to close, the earphones is no more in the paired device list when I issue the list command but still in the connected device when I issue status command.

Have you experienced similar bugs ? Some hints to avoid the nasty reset solution ?
