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.
