There is a bt power issue on Debian OS, the blueman app
will callback to enable the bluetooth power during the bringup.
As below log the system bringup about 10s.
[BT_RFKILL]: rfkill_rk_set_power: set bt wake_host pin output high!
[BT_RFKILL]: rfkill_rk_set_power: enable bt reset pin!
[BT_RFKILL]: ENABLE UART_RTS
[BT_RFKILL]: DISABLE UART_RTS
[BT_RFKILL]: bt turn on power
...
So the rfkill-bt driver should judge the power status, otherwise the
blueman app will cause the bluetoolth timeout error. e.g:
root@linaro-alip:/# bluetoothctl
[NEW] Controller 3B:A0:90:48:46:40 linaro-alip [default]
