Hi,
i have the following query.
a) (headset.c) headset_unlock
->headset_set_state(...HEADSET_CONNECTED),which in turn calls the
close_sco.
close_sco calls g_io_channel_shutdown().
I want to know whether g_io_channel_shutdown() triggers the sending of
HCI_Disconnect_Req(to remove SCO) to the LMP .
b) Also wanted to know,will the user mode BlueZ get an indication ,(if
so through which function),when the LMP sends a Disconnect Complete
Event to the Host.
I am asking the above as i see in the HCI dump, Disconnect &
Disconnect Complete messages, the issue i am facing is user mode BlueZ
calls close_sco & then calls headset_request_stream which again asks
for sco_connect(). Before the Disconnect Complete Evt is posted by
LMP. LMP reports Synchrnous Connection LImit to Device Exceeded(0X0A)
for the Synchrounous Setup Complete .
Snippet of hcidump is given below:
