Release of BlueZ 5.65

This release includes many changes related to the IOS support such as supporting ISO socket via experimental feature support and updating the monitor and tools. It also contains numerous bug fixes on A2DP, AVRCP, SDP, HOG, GATT, and MESH.


Release of BlueZ 5.64

This is another release mostly with the bug fixes on HOG, GATT, A2DP, Media, AVDTP, AVRCP, and scanning failure. Also, this release includes a fix for building with old glibc (< 2.25), and other minor issues found with the static code analyzing tool. ISO packet support is added to the emulator as a part of LE Audio development.


Release of BlueZ 5.63

This release is mostly a bug fix release, with fixes to features such as GATT, SDP, Daemon, and emulator. It also adds a new MGMT Event for Device Found and Device Lost of Advertisement Monitor.

New build options for sanitizers (lsan, asan, ubsan) are added and it may require installing additional libraries depending on the distros.


Study Guide for Linux Developer

The Bluetooth SIG provides the self-study guide for Linux developers to explain the Bluetooth applications on Linux that uses D-Bus and BlueZ stack:

  • Includes a basic introduction to Bluetooth Low Energy (LE).
  • Explains the architecture of Bluetooth systems on Linux
  • Covers the key concepts relating to the interprocess communication system D-Bus and how it is used with the BlueZ stack.
  • Explains how to use D-Bus from the Python programming language to make and receive remote method calls and to emit and receive D-Bus signals.
  • Explains how to write code that acts as a Bluetooth LE Central device using Python, D-Bus and BlueZ, using practical exercises to compliment the theory.
  • Explains how to write code that acts as a Bluetooth LE Peripheral device using Python, D-Bus and BlueZ, using practical exercises to compliment the theory.
  • Illustrates how to set up your Linux kernel and build BlueZ from source to create a Linux environment for Bluetooth application development.

Release of BlueZ 5.62

This release updates the sources to use the inclusive language based on the guide from the Bluetooth SIG(Appropriate-Language-Mapping-Table), updates the DBUS API to add new properties for GATT and Adapter. For MESH, it updates the configuration client and adds a new API to export the keys. It adds a new document to describe the errors of D-BUS method returns for connection failure reasons. In addition, it includes the various bug fixes in Core, ATT, AVCTP, AVDTP, and MGMT API.

It recommends using the ELL version 0.44.


Release of BlueZ 5.61

This is mostly a bugfix release with fixes in A2DP, OBEX, adapter, and emulator. It also includes new features like plugin for admin policy, Central Address Resolution characteristic in GATT, packet latency analysis in the monitor.


Release of BlueZ 5.60

This release has bug fixes to GATT, Management API, and Advertising Monitor. It also fixes the regression introduced in the 5.59 release with the newly paired A2DP headset.

It recommends using the latest ELL release.
