BCM4356 bluetooth HFP audio is not working with IMX8 Android Pie

vinothkumars — Mon, 30 Mar 2020 10:16:43 GMT

Dear All,

I am working on bcm4356 with imx8 android automotive. A2DP profile is working fine. But, when I try bluetooth call hfp enabled properly but, unable to get any sound.

A2DP profile is working with Speaker ? But, same setup is not working for HFP.

Do, I needs to do any configuration ?

Please find log,

Re: BCM4356 bluetooth HFP audio is not working with IMX8 Android Pie

Hi,

From this log I come to know, trying to connect headset

Telecom : BluetoothRouteManager: getBluetoothAudioConnectedDevice: no headset service available.: (...->CS.crCo->H.CS.crCo->H.CS.crCo.pICR)->CSW.hCCC->CILH.sL->CILH.oQC->ICF.oCFC->CAMSM.pM_2002->CARSM.pM_SWITCH_FOCUS@E-E-ACk

Do we needs to do any configuration for wired speaker ?

Thank You,

VInoth S,

Hi,

We got some noise from speaker during a call when using a Bluetooth connection.

Do we needs to do any configuration ?

We got some observation from codec side,

Input Sampling Rate - 48k

Output Sampling Rate - 8k

Let me know, Which file do I needs to configure sampling rate ?

Thanks & Regards,

VInoth S,

We Changed the hfp_set_sampling_rate to 48k. But same noise observed from speaker side.

Here I have some question,

1. Do I needs to update the broadcom firmware on Android 9 Automotive ?

2. Do I needs to do any hardware changes ?

3. Do I needs to do any software changes ?

Thanks & Regards,

Vinoth S,
