[PATCH BlueZ v2 0/4] Update bcast ep register and config props

[PATCH BlueZ v2 0/4] Update bcast ep register and config props

[Iulia Tanasescu]

This patch removes unnecessary input prompts from broadcast ep register.
It also adds support to provide stream config options at broadcast
source endpoint config.

This is useful for a broadcast source supporting multiple streams,
since each stream could require a different config.

In client/player, the input prompts have been updated for broadcast
endpoint register and config: At broadcast ep register, the user will
enter the locally supported stream locations and context types.

At broacast source ep config, the user will provide the BIG that the
new stream will be part of, the stream Channel Allocation, and the
metadata of the subgroup to include the stream. These options will be
used to configure the BASE and the BIG.

[PATCH BlueZ v2 4/4] client/player: Update bcast endpoint input prompts

[Iulia Tanasescu]

This updates the input prompts for broadcast endpoint register and
config.

To register a broadcast endpoint, the user will be asked to enter
the supported stream locations and context types.

At broadcast source endpoint config, the user will provide stream
config options: The BIG that the new stream will be part of, the
stream Channel Allocation, and the metadata of the subgroup to
include the stream. These options will be used to configure the
BASE and the BIG.

The flow to create a Broadcast Source is the following:

[bluetooth]# endpoint.register 00001852-0000-1000-8000-
00805f9b34fb 0x06
[/local/endpoint/ep0] Auto Accept (yes/no): y
[/local/endpoint/ep0] Max Transports (auto/value): a
[/local/endpoint/ep0] Locations: 3
[/local/endpoint/ep0] Supported Context (value): 15
[NEW] Endpoint /org/bluez/hci0/pac_bcast0
Endpoint /local/endpoint/ep0 registered

[bluetooth]# endpoint.config /org/bluez/hci0/pac_bcast0
/local/endpoint/ep0 16_2_1
[/local/endpoint/ep0] BIG (auto/value): 1
[/local/endpoint/ep0] Enter channel location (value/no): 3
[/local/endpoint/ep0] Enter Metadata (value/no): 0x03 0x02
0x04 0x00

To create a Broadcast Sink, enter the following:

[bluetooth]# endpoint.register 00001851-0000-1000-8000-
00805f9b34fb 0x06
[/local/endpoint/ep0] Auto Accept (yes/no): y
[/local/endpoint/ep0] Max Transports (auto/value): a
[/local/endpoint/ep0] Locations: 3
[/local/endpoint/ep0] Supported Context (value): 15
