Subject: [Bluez-devel] How can I set CSR module as PCM master?
Date: Tue, 26 Jul 2005 16:30:00 +0800 (CST) [thread overview]

Hi,
I want to transmit voice data through CSR modules so
that I can talk with others using speaker and
microphone.And I connecte a C145483 Codec throught PCM
interface .But unfortunately,CSR module doesn't send
the PCM clock and sync,so the Codec doesn't work.And
now, I know that when the CSR module is set as a PCM
master it will send the PCM clock. However ,I don't
know how to do that. I can change the PCM mapping
using pskey just like this:
$ pskey -i hci0 mapsco 0
$ hciconfig hci0 revision
hci0: Type: UART
BD Address: 4A:49:4E:00:15:2F ACL MTU: 384:4
SCO MTU: 64:8
Build 705
Chip version: BlueCore02-External
Max key size: 56 bit
SCO mapping: HCI
So, what can I do?
Thanks in advance!
gadfly
