Re: Software caused connection abort (103 )

[john michelle <jhnmichelle@gmail.com>]

Dear Bluetooth community,

You are committing version after version and have time to add new
Features and the core stack have a major bug (software Caused
connection abort) that i
Have reported on the 7th of may the problem seems to be either in the
usb part of the
Kernel or the bluez stack, i am no kernel engineer so i came directly
to you for reporting
This problem and my requests to look into this problem are just
ignored. this is a blocker
Issue that would prevent and discourage any one from developing
application that rely on
Bluez sco capabilities, since during transmission the above mentioned
error just occurs.
I hope that my voice is heared and i would get a reply from the bluez commu=
nity.

John
