Create a local endpoint and an endpoint for BIS1:
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: 0x03
[/local/endpoint/ep0] Supported Context (value): 0

Configure BIS1, create BIS1 transport and endpoint for BIS2:
endpoint.config /org/bluez/hci0/pac_bcast0 /local/endpoint/ep0 48_4_1
[/local/endpoint/ep0] BIG (auto/value): 0x01
[/local/endpoint/ep0] Enter channel location (value/no): 0x01
[/local/endpoint/ep0] Enter Metadata (value/no): n

Configure BIS2, create BIS2 transport and endpoint for BIS3:
endpoint.config /org/bluez/hci0/pac_bcast0 /local/endpoint/ep0 48_4_1
[/local/endpoint/ep0] BIG (auto/value): 0x01
[/local/endpoint/ep0] Enter channel location (value/no): 0x02
[/local/endpoint/ep0] Enter Metadata (value/no): n

For multiple BISes acquire must be called on all transports
before the BIG is created:
transport.acquire /org/bluez/hci0/pac_bcast0/fd0
transport.acquire /org/bluez/hci0/pac_bcast0/fd1
.....
transport.release /org/bluez/hci0/pac_bcast0/fd0
transport.release /org/bluez/hci0/pac_bcast0/fd1
