Hi, after implementing fixes for bluetooth pairing and connection (https://jira.automotivelinux.org/browse/SPEC-293), we confirmed the connection is HFP and AVP connection. However when we try to play the music, or even when we just open the player on the phone side, we can observe that the AVP connection is disconnected. We think BlueZ side trigger the disconnection. We are wondering there is something wrong with our procedure or BlueZ. We updated master yesterday, so we think we use newest master version, included modules for pulseaudio. We are investigating right now. If someone have some advice, it will be appreciated.
