Dear All:
I am currently trying to extend a bluetooth channel driver (chan_mobile) for
Asterisk (a VoIP PBX).
Now I have a few questions about SCO in bluez stack.
(1) Does latest Bluez support multiple SCO from one USB dongle to multiple
cell phones (Hands-Free Profile)?
According to this discussion thread
http://thread.gmane.org/gmane.linux.bluez.devel/12893/focus=12903, the
hci_usb.c is not patched to fully support multiple SCO links for a single
USB dongle. (But the weird thing is the original poster gets things to work
by only removing wrong usage in socket setting).
(2) Is there any simple way to test the simultaneous SCO connections from
one dongle to two cell phones? By using socket, I know we can send data and
receive from the remote side. But as for interacting with cell phone's
Hand's Free Profile, is there any simple way? such as pressing the button on
the phone?
(3) Is there any way to check the packet type of baseband controller of the
USB bluetooth dongle (HV2 or HV3..)? since the hci_dump or hcitool can only
retrieve or dump the hci message.
Thanks.
