Hi All,

I came across hstest program. It is able to connect to RFCOMM and SCO channels with HS850. I also see AT+VGS=15 command and few beeps. But i am not able to hear audio. Also i cannot playback recorded file. I see SCO packets in hcidump output while both playing and recording.
Pls help.

I am using following commands,
./hstest play KDE_startup_new.wav <bt_add> 1
./hstest record a.wav <bt_addr> 1

Regards,
Manoj

Hello,

I want to receive audio from HS850 headset. I have
connected RFCOMM channel 3 and able to receive AT
command when key is pressed. But when i try to connect
SCO channel using SCO socket program on channel 1, i
get "No Route found (113)". I am using bluez 3.1.
Has anyone seen similar issue? Are there any special
tests needed to do this?

Pls let me know. I have pasted sdptool and hcidump
outputs below.

regards,
Manoj

The sdptool records gives follwing output.
