I am using Raspberry Pi 3 (with wifi+bluetooth).
When using the command tool, bluetoothctl, it can detect old and new bluetooth devices (version > 4.0).

However, using the bluetoothlaz inside my lazarus app, it can only detect old bluetooth devices (not the BLE new devices).

I am guessing the bluetoothctl uses the new version and features in bluez (ver 5.41) but bluetoothlaz uses the
{$linklib bluetooth}

which probably is the file
/usr/lib/arm-linux-gnueabihf/libbluetooth.so.3
which is a symbolic link to
/usr/lib/arm-linux-gnueabihf/libbluetooth.so.3.18.13

which might probably be compiled with old versions of bluez (or turn off the BLE feature).

Do you think my guess is correct?

If yes, can anyone point me to how to update the libbluetooth.so ? Should I compile a new .so? How (I am bad in linux).

Thanks a lot in advance.

On Ubuntu bluetoothctl does not link to "bluez". Only basic libs.

Sounds right.

Don't know.

Maybe libbluetooth supports the new features, but bluetoothlaz misses the new functions?
