How to send manufacturer specific command directly within bluealsa/bluez?

[AlphaOx42]

Hi everyone,

I am currently using a Infineon (Cypress) module based on the CYW4343W chipset and I was experiencing audio dropouts when establishing a new connection while streaming A2DP.

According to Infineon we must change the priority of the A2DP stream as workaround, which also seems to be working.
But currently I'm setting the priority using the following command:
hcitool -i hci0 cmd 0x3f 0x11a <connection handle> 0x01 0x01

I'd prefer avoiding a running such command and directly set this priority from bluealsa/bluez when starting and stopping an A2DP stream. I'm not so confident in the bluealsa stack, so I am unsure where and how I can achieve this goal ?

Every help is welcome
cheers

This appears to be related to an issue recently raised in Bluez: bluez/bluez#722

Its not clear whether the Bluez team intend to progress any of the suggestions in there though.

Yes I saw this issue, I'd hoped there is another possibility.
Thank you for your feedback. I guess I'd to go the easier way and use hcitool.
