Commit 947ee152d3 ("bluez: check dbus service before enumerating objects")
introduced a check that would esure that GetManagedObjects()
is not called if the "org.bluez" name has no owner. This
was done to avoid auto-starting the bluez daemon.
However, this is not needed because it is possible to set on
a per-message basis whether or not the destination service
should be automatically started by the dbus daemon.
When we were using the resampler and then bypass it when the configured
rate == 1.0, we create a pop because we don't process the queued data in
the resampler anymore.
Avoid this by keeping the resampler active as soon as the rate property
is set on the audioconvert. The resampler itself will use a more
efficient copy method in that case anyway and it is expected that the
rate will change again later when we need to reactivate the resampler.
By default no modem is allowed.
Property "bluez5.hfphsp-backend-native-modem" can be 'none', 'any' or the
modem device string has found in 'Device' property of
org.freedesktop.ModemManager1.Modem interface, e.g. for PinePhone
"/sys/devices/platform/soc/1c1b000.usb/usb2/2-1".
This allows the HFP HF to retrieve the list of calls with their index,
state and remote number (if available).
This commit shared the list of calls between modemmanager.c and
backend-native.c, and switches call state storage from ModemManager
states to CLCC states
Allow to answer, reject or terminate a call.
Answering or rejecting a call can only be done on an incoming call.
Terminating a call can only be done on active, dialing or alerting call.
The Voice object lists the Call objects, which provides status of each call.
+CIND call indicator is set if at least one of the call is active.
+CIND callsetup indicator is set if one of the call is in ringing in or out
or dialing state.
The Modem object provides the own number (used by +CNUM), the network
service availability and signal strength (used for the +CIND).
+CIND indicators can be activated/deactivated using AT+BIA except for
call, callsetup and callheld indicators which should always reported.
All indicators are enabled on connection.
uint32_t i;
for (i = 0; i < SPA_N_ELEMENTS(some_array); i++)
.. stuff with some_array[i].foo ...
becomes:
SPA_FOR_EACH_ELEMENT_VAR(some_array, p)
.. stuff with p->foo ..
So that we can reuse optimized versions in unoptimized noise
functions.
Do allocation a little different so that we can align everything
from the start.
Loop though coefficients, when all are 0, clear the destination.
When only one coefficient is used, simply copy with volume.
Otherwise run the complete convolution.
Don't count the sum for unused matrix coefficients. When doing pairing,
we set the mask to ~0 and so we would otherwise count too much.
Apply normalization to the active matrix coefficients, not whatever the
loop variables end up being at the end of the loops.
A flush command is not supposed to stop playback but just clear the
current state. Normally, to avoid complications, an application will
Pause, Flush and optionally Start to do things smoothly without
interfering with the process loop, but things should not crash if that's
not the case.
Fixes#2726
HFP 1.8 states in 4.35.1:
Due to the small inconsistency between the GSM standard [2]) and the current
Headset specification ([3]), the HF shall also accept the “=” symbol,
in place of “:”, as a valid separator for this unsolicited result code.
iOS seems to use "=", so accept that as well.
See #2463
Both HFP and HSP require an AT command from HF/HS to AG to
be terminated by CR, not LF. (HFP 1.8, 4.34.1; HSP 1.2, 4.8.1)
See #2463
Fixes: 0b2d3730b6 ("bluez5: Add HFP HF support")
`strsep()` is simpler to use than `strtok()` or `strtok_r()`
while being thread-safe and reentrant.
Although it is an extension, it is available in both glibc and musl.
