We don't initially have the SAP socket open, so we can't generate an SDP
(because we don't have the interface address). So in addition to the
regular flow, also trigger SDP creation after opening the SAP socket, so
we can have a valid SDP for the announcement.
The sending was broken in commit a44afd84. We delay the SAP fd openeing
for reasons explained in commit f2f204d6).
As AG, set node.rate for output streams that originate from remote
source, so that graph switches rate as needed. This follows what
pipewire-pulse etc. do.
The patch is by Wim.
When both node and port are given, check that the port belongs to the
node. If it doesn't, it could be that we found a Port using the
object.id but we should have used the port.id of the node.
The transport update is set in the node properties. If one client tries
to start and another tries to stop we have two conflicting desired states
in the nodes.
Fix this by making the state update a one time property and remove it
from the sever and client properties after updating it. We then need to
keep the new state around and apply it once.
Keep the node driver state as it is unless there was a transport state
update.
Fixes#4543
In this error condition, execution is supposed to return immediately
because rfcomm is no longer valid. However, the code was incorrectly
changed to jump to the done label, which would try to use rfcomm
again to process pending commands.
To be sure that the AG reply correspond to the command sent, this
postpone the new command if previous reply (OK, ERROR or +CME) has
not yet been received.
The postponed command is sent on reception of the reply.
This allows implementing UI mechanisms to transfer the audio of a call
to the HF (pipewire) only when the user explicitly asks/allows it.
Normally, when a call is connected, the phone initiates a SCO connection
and the HF accepts it, transfering audio automatically. In order to
allow for user interaction, this patch enables the UI to set the RejectSCO
property to 'true' in order to automatically reject the SCO connection.
Later on, at the UI's discression, the audio may be reconnected by calling
the Activate() method, which sends AT+BCC to re-initialize the SCO channel.
A configuration file option is also added to configure the default value
of the RejectSCO property. By setting this to 'true' in the config file,
it is possible to implement rejecting the audio of a call that is already
active at the time the Bluetooth connection to the phone initializes.
This is useful for implementations that do hardware offloading of the
SCO audio channel and need to communicate state information to the
hardware (at least).
Start call id at 1 as for the index calls in HFP, and move this id
to spa_bt_telephony_[ag|call] so they can be used by CLCC to retrieve
the related call.
if enhanced call status is supported, send AT+CLCC on +CIEV events to
get the calls information.
The HF should declare the features supported before trying to send
related AT commands.
It should only send AT+CHLD related commands if the remote AG supports
them.
On some phones (at least), sending AT+CHLD=0 while there is no held
call returns an error. Make sure we don't do this to avoid returning
an error on D-Bus when in fact hangup_all actually succeeds.
