Since the transport.select command should also work for transports created by audio servers, the transport should not be required to be associated with a local bluetoothctl endpoint, to avoid errors like below: [bluetoothctl]> scan on [bluetoothctl]> [NEW] Device 1C:F1:FA:E7:B0:3F 1C-F1-FA-E7-B0-3F [1C-F1-FA-E7-B0-3F]> [NEW] Transport /org/bluez/hci0/dev_1C_F1_FA_E7_B0_3F/bis1/fd0 [1C-F1-FA-E7-B0-3F]> [NEW] Transport /org/bluez/hci0/dev_1C_F1_FA_E7_B0_3F/bis2/fd1 [1C-F1-FA-E7-B0-3F]> transport.select /org/bluez/hci0/dev_1C_F1_FA_E7_B0_3F/bis1/fd0 /org/bluez/hci0/dev_1C_F1_FA_E7_B0_3F/bis2/fd Local endpoint not found This reworks transport.select to use a dedicated structure to hold information about the transport and its links, instead of using the local endpoint. --- client/player.c | 160 +++++++++++++++++++++++------------------------- 1 file changed, 77 insertions(+), 83 deletions(-)
