Sender: bluez-users-admin@lists.sourceforge.net Errors-To: bluez-users-admin@lists.sourceforge.net Reply-To: bluez-users@lists.sourceforge.net List-Unsubscribe: , List-Id: BlueZ users List-Post: List-Help: List-Subscribe: , List-Archive: Date: Thu, 21 Jul 2005 17:25:38 +0800 (CST) My case is as fllows: I use two CSR(Bluecore2) modlues on two arm platforms respectively ,what I want to do is that I can use bluez stack on arm platform sucessfully.And now,I can create ACL and SCO connection,both l2test and scotest run well.Even,I can transmit files using the program obex_test. I just want to transmit voice data through bluetooth modules so that I can talk with others using microphone.And I connected a MC145483 Codes(13-bit Line ) throught PCM interface. What I did is as follows: on platform A: $ rfcomm listen 0 5& Waiting for connection on channel 5 $ scotest -r scotest[114]: Waiting for connection ... on platform B: $ hstest play wrong.mp3 4A:49:4E:00:15:2F 5 Voice setting: 0x0060 RFCOMM channel connected SCO audio channel connected (handle 44, mtu 64) then, on platform A, I recieve : scotest[87]: Connect from 4A:49:4E:00:15:2D [handle 45, class 0x000000] scotest[87]: Receiving ... scotest[87]: 728 bytes in 0.00m speed 4.43 kb scotest[87]: 728 bytes in 0.00m speed 4.55 kb scotest[87]: 728 bytes in 0.00m speed 4.55 kb ...... Then ,I can't hear anything from the speaker of MC145483 Codec on platform A! If try hsmicro on platform B: $ hsmicro 4A:49:4E:00:15:2F 1 -t: No such file or directory Voice setting: 0x0060 RFCOMM channel connected SCO audio channel connected (handle 44, mtu 64) R I N G O K O K .... on platform A,receive the same message as above ! And ,A and B can't change role each other, if A send and B listen,then B can't recieve anything! Please correct me if i"m wrong. I wonder if I can use headset profile or not! after all, my hardware is just bluetooth module instead of Headset! Or maybe there is something wrong on the connection between Bluetooth module"s PCM interface and the Motoral MC145483 Codec? This Codec is a 13-bit line PCM Codec, maybe the voice data format is wrong ?
