scotest keeps waiting for connection

scotest keeps waiting for connection

[Nikunj A. Dadhania]

Hi,

I am trying to run scotest across two BT modules. Both are running
kernel 2.6.29-4.

On my laptop I give following command:

[test@localhost test]$ ./scotest -r
scotest[5167]: Waiting for connection ...

On the other PC i am giving following command

[root@dhruv test]$ ./scotest -s -b 64 00:16:41:99:2E:16
scotest[16681]: Connected [handle 46, class 0x000000]
scotest[16681]: Sending ...
scotest[16681]: Send failed: Connection reset by peer (104)
[root@dhruv test]#

When I see the hcidump output it seems that initial SCO connection goes
through successfully. But after sending some SCO data, the remote side
terminates the connection. Also, the remote side does not receive
anything.

Am i missing something here?

Regards,
Nikunj
