Release of BlueZ 5.23
This is mostly a bug-fix release with fixes for concurrent authorization attempts (for untrusted devices), HID, uHID, OBEX, MAP and AVRCP. We now also have better support for AVCTP/AVRCP decoding with btmon.
On the Android side a notable enhancement is the ability to take advantage of kernel whitelist support to enable LE passive scanning (something that’s available from Linux Kernel release 3.17 onward)..
