wl1271 Bluetooth can't demo with HFP

Check whether wl1271-pcm has been registered as a digital audio device by executing command "aplay -l". The aplay -l lists audio devices available on the system.

Dear Sinoj .

When edit file /etc/asound.conf below (comment all)

#
#pcm.!bluetooth {
#    type bluetooth 
#    device
#    }

#pcm.!default {
#    type plug
#    slave.pcm bluetooth
#    }


# aplay -l

**** List of PLAYBACK Hardware Devices ****
card 0: omap3beagle [omap3beagle], device 0: TWL4030 twl4030-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0



But If running BT_Demo.sh for HSP Test or BT_HSP_Init.sh will change /etc/asound.conf to below,
'/etc/asound.conf' got updated, Ensure that we will pair to the device  for HFP


pcm.!bluetooth {
    type bluetooth 
    device
    }

pcm.!default {
    type plug
    slave.pcm bluetooth
    }

aplay -l wll return error below

Any suggestion ?  thank you inadvance

Please let us know the version of the SDK release you are currently using. The latest SDK release does not support HFP on the AM37xx EVM as per the release notes (http://processors.wiki.ti.com/index.php/AM37x_Wireless_Connectivity_release_notes). So i  assume that you are using some older version of SDK for AM37xx EVM. If that is the case, kernel has to be modified by applying one patch (PSP-03.00.00.05-and-wl1271-6.1.5.4-integration.patch) to support HFP over pcm interface of the WL1271 which is connected to the McBSP 1 port of the AM37xx processor (HFP over HCI is not supported). If that patch is applied, the aplay -l command will list wl1271-pcm card as well. The patch can be used if the wl1271-pcm interface is connected to McBSP port 1. The BT_HSP_Init.sh is not used in the BT_Demo.sh. Am i right?

Dear Sinoj,

Thank you for your help,

I'm using DM3730, and use SDK and WiFi/BT on below  link,
Kernel 2.6.32  URL: http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_4_00/4_01_00_09/index_FDS.html

Above driver , Are they still need to patch with "PSP-03.00.00.05-and-wl1271-6.1.5.4-integration.patch" or not ?

1. The BT_HSP_Init.sh is not used in the BT_Demo.sh. Am i right?
Yes,  

I just mean using BT_Demo.sh and select HSP Test  or
using BT_Init.sh + BT_HSP_Init.sh the result are same ( error with aplay -l )


Thank you in advance.

Yes, the kernel has to be rebuilt with the patch applied.

Sinoj
