This fixes the transport select flow in bluetoothctl: If the user tries to select multiple encrypted transports, the prompts for the Broadcast Code overlap, causing the UI to be distorted: [11-AE-0A-C1-F4-30]# transport.select /org/bluez/hci0/dev_11_AE_0A_C1_F4_30/bis1/fd0 /org/bluez/hci0/dev_11_AE_0A_C1_F4_30/bis2/fd1 [] Enter brocast code[value/no]: Successfully linked transport /org/bluez/hci0/dev_11_AE_0A_C1_F4_30/bis2/fd1 [] Enter brocast code[value/no]: Borne House (null)Setting broadcast code succeeded (null)[CHG] Transport /org/bluez/hci0/dev_11_AE_0A_C1_F4_30/bis1/fd0 State: broadcasting (null)Select successful (null) This commit updates the transport select command handler to first link all transports before setting the Broadcast Code only on the primary link (the Broadcast Code is common for all BISes in the BIG). After the Broadcast Code is successfully set, each link is selected one by one. The bluetoothctl log below shows the updated output: client/bluetoothctl [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: 1 [/local/endpoint/ep0] Supported Context (value): 1 [bluetooth]# Endpoint /local/endpoint/ep0 registered [bluetooth]# scan on [bluetooth]# [NEW] Device 11:16:BD:36:58:3F 11-16-BD-36-58-3F [11-16-BD-36-58-3F]# [CHG] Device 11:16:BD:36:58:3F Connected: yes [11-16-BD-36-58-3F]# [NEW] Transport /org/bluez/hci0/dev_11_16_BD_36_58_3F/bis1/fd0 [11-16-BD-36-58-3F]# [NEW] Transport /org/bluez/hci0/dev_11_16_BD_36_58_3F/bis2/fd1 [11-16-BD-36-58-3F]# transport.select /org/bluez/hci0/dev_11_16_BD_36_58_3F/bis1/fd0 /org/bluez/hci0/dev_11_16_BD_36_58_3F/bis2/fd1 [11-AE-0A-C1-F4-30]# Successfully linked transport /org/bluez/hci0/dev_11_AE_0A_C1_F4_30/bis2/fd3 [] Enter brocast code[value/no]: Borne House [11-AE-0A-C1-F4-30]# Setting broadcast code succeeded [11-AE-0A-C1-F4-30]# [CHG] Transport /org/bluez/hci0/dev_11_AE_0A_C1_F4_30/bis1/fd2 State: broadcasting [11-AE-0A-C1-F4-30]# Select successful [11-AE-0A-C1-F4-30]# [CHG] Transport /org/bluez/hci0/dev_11_AE_0A_C1_F4_30/bis2/fd3 State: broadcasting [11-AE-0A-C1-F4-30]# Select successful [11-AE-0A-C1-F4-30]# transport.acquire /org/bluez/hci0/dev_11_AE_0A_C1_F4_30/bis1/fd2 /org/bluez/hci0/dev_11_AE_0A_C1_F4_30/bis2/fd3 auto acquiring...
