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
[bluetooth]# scan on
[NEW] Endpoint /org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/
pac_bcast0
[bluetooth]# endpoint.config
/org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/pac_bcast0
