Hello Luiz.
I am not registred in email-list because from that email to me from vger.kernel.org recieve error, but from my iphone email vger.kernel.org think i am send HTML message - and add me a SPAM.
If you may send your email to that email direct please.
Excuse me ,in last message i am did bad titile . My problem not "How connect two headphones to Bluetooth" , my problem How connect two headphones to ONE Bluetooth adapter.
I am conducted a study source codes of Bluez. What i am understand.
>From file bluez-5.46/profiles/audio/avdtp.c :
if (lsep->info.inuse)
return NULL;
How i am undestand count of endpoints for one Bluez adapter depend from count calling D-bus functions "RegisterEndpoint".
>From file pulseaudio-11.0/src/modules/bluetooth/bluez-util5.c :
if (pa_streq(interface, BLUEZ_ADAPTER_INTERFACE)) {
pa_bluetooth_adapter *a;
if ((a = pa_hashmap_get(y->adapters, path))) {
pa_log_error("Found duplicated D-Bus path for adapter %s", path);
return;
} else
a = adapter_create(y, path);
pa_log_debug("Adapter %s found", path);
parse_adapter_properties(a, &iface_i, false);
if (!a->valid)
return;
register_endpoint(y, path, A2DP_SOURCE_ENDPOINT, PA_BLUETOOTH_UUID_A2DP_SOURCE);
register_endpoint(y, path, A2DP_SINK_ENDPOINT, PA_BLUETOOTH_UUID_A2DP_SINK);
How i am undestand in pulseaudio for one adapter - only two endponts - one sink and one source
>From ADVANCED AUDIO DISTRIBUTION PROFILE SPECIFICATION (2015-07-14):
- The profile does not support a synchronized point-to-multipoint distribution
>From https://www.bluetooth.com/specifications:
Bluetooth BR/EDR enables continuous wireless connections and uses a point-to-point (P2P) network topology to establish one-to-one (1:1) device communications.
My questions:
1) Am I right with my conclusions?
2) Bluez is it suitable for connecting two headphones to one adapter? - how i am seen : yes (queue for server sources and sinks)
3) Pulseaudio is it suitable for connecting two headphones to one adapter? - how i am seen : not (only two D-bus calls RegisterEndpoint - for sink and for source)
4) Why two headphones with one Bluetoth adapter working on Windows XP? ( https://www.youtube.com/watch?v=yOxg23jXSio&t=5s)
Best regards,Ruslan.
