In line 1517, Bluedroid kills bluetoothd because an HCI command fails. After that, the restart and reconnect fails.

The log shows preload_wait_timeout, which means libbt cannot get HCI response even restart bluetooth daemon.
I'm not sure the problem is related to UART driver or we need to reset bluetooth chipset via RX/TX pin.

Is it specific to aries-l or aries-kk? Any STR you can share?

That's the fun thing, it's on Z3 Tablet Compact, which has the same bluetooth chip as far as I can say than Z3 Compact. It's on Lollipop. STR is just "Enable bluetooth".

Do you need extra firmware?

Comment 6

[Shawn Huang [:shawnjohnjr][:shuang] (as a happy gecko contributor)]

Do you build libbt-vendor.so from libbt or use proprietary blob file libbt-vendor.so? We used to have problems when porting z3c compact on lollipop. Maybe z3 tablet compact uses different configuration '$(BOARD_BLUEDROID_VENDOR_CONF)' than z3c? Maybe vnd_generic.txt configuration is different.
