HFP and A2DP IMPLEMENTATION WITH 88W8987 Based BT module

[Wobaffet]

Hello,

We are trying to implement A2DP and HFP with i.MX8MP custom board. We can load the firmware and connect to any BT device, however when we try to

We can't detect a card for the connected devices as can be seen on this guide.  Even though we can detect Audio sink feature like this

	Modalias: bluetooth:v000ApFFFFdFFFF

We are on 5.15 kernel and our distro has these packages

IMAGE_INSTALL:append = "dbus packagegroup-tools-bluetooth pulseaudio pulseaudio-server pulseaudio-miscbluealsa alsa-lib bluez5 bluez5-noinst-tools bluez5-obex openobex obexftp"

When we try to load discover module we get

root@imx8mp-lpddr4-evk:~# pactl load-module module-bluez5-discover
Failure: Module initialization failed

 Also the list of pactl modules are attached.

What could be the issue here?

Thanks!

Hello,

Could you show me how you connect the module? 

What is the boot up log?

Please also send me the device tree file of your board for checking.

Thanks.

Best regards,

Jimmy
