Does the 88W8997 support PCM loopback mode?

[jimi_lin]

HI

We are using the 88W8997 chip.

We try to enable the PCM loopback mode as below hci cmd, but it seems the loopback cmd is not working.

hcitool -i hci0 cmd 0x3F 0x1D 0x01
hcitool -i hci0 cmd 0x3F 28 0x03 0x00 0x00
hcitool -i hci0 cmd 0x3F 0x07 0x00
hcitool -i hci0 cmd 0x3F 0x29 0x04 0x00
hcitool -i hci0 cmd 0x3F 0x2F 0x03

Did i miss anything? Or?

And does 88W8997 support PCM loopback mode?

Thanks

Hi Jimi,

I hope you are doing great. 

I have been checking the internal support. and they provide a different commands to set up the mode that you are trying to do.

However, could you please create a new ticket for internal support.

HI Mario

So, does the 88W8997 support PCM loopback mode?

I got the response from NXP.com, it seems that 88W8997 does not support PCM loopback mode now.

Is it correct?

Thanks
