BlueZ - Bluetooth protocol stack for Linux ****************************************** Copyright (C) 2000-2001 Qualcomm Incorporated Copyright (C) 2002-2003 Maxim Krasnyansky <maxk@qualcomm.com> Copyright (C) 2002-2010 Marcel Holtmann <marcel@holtmann.org> Compilation and installation ============================ In order to compile Bluetooth utilities you need following software packages: - GCC compiler - GLib library - D-Bus library - udev library (optional) - readline (command line clients) On a debian based system, this can be done by running the following command: sudo apt-get build-dep bluez ./bootstrap To configure run: ./configure --prefix=/usr --mandir=/usr/share/man \ --sysconfdir=/etc --localstatedir=/var Configure automatically searches for all required components and packages. To compile and install run: make && make install Embedded Linux library ====================== In order to compile mesh support and test client utility the development version of Embedded Linux library is required to be present. The development repositories can be found here: git://git.kernel.org/pub/scm/libs/ell/ell.git https://kernel.googlesource.com/pub/scm/libs/ell/ell.git The build systems requires that the Embedded Linux library source code is available on the same top level directory as the source code: . |--- ell | |--- ell | `--- unit `--- bluez |--- src `--- tools It is not required to build or install Embedded Linux library. The build will happen when building the binaries and it will then be linked internally. When using --enable-external-ell build option, it is not required that the Embedded Linux library source code is available in the top level directory. When neither --enable-mesh nor --enable-btpclient is specified, then this part is irrelevant and Embedded Linux library is not required. Kernel Build Options (for Mesh) =============================== The Mesh daemon uses kernel provided crypto utilities to perform security functions required of Bluetooth Mesh. Many standard distributions currently enable all required crypto features, but a few notable distributions do not. If Mesh Cryptography is not working, the following configuration options may need to be enabled, and the kernel rebuilt. 1. A minimum of kernel version 4.9 or later is required 2. The kernel must at a minimum have the following .config options turned on: CONFIG_CRYPTO_USER CONFIG_CRYPTO_USER_API CONFIG_CRYPTO_USER_API_AEAD CONFIG_CRYPTO_USER_API_HASH CONFIG_CRYPTO_AES CONFIG_CRYPTO_CCM CONFIG_CRYPTO_AEAD CONFIG_CRYPTO_CMAC Configuration and options ========================= For a working system, certain configuration options need to be enabled: --enable-library Enable installation of Bluetooth library By default the Bluetooth library is no longer installed. The user interfaces or command line utilities do not require an installed Bluetooth library anymore. This option is provided for legacy third party applications that still depend on the library. When the library installation is enabled, it is a good idea to use a separate bluez-library or libbluetooth package for it. --disable-tools Disable support for Bluetooth utilities By default the Bluetooth utilities are built and also installed. For production systems the tools are not needed and this option allows to disable them to save build time and disk space. When the tools are selected, it is a good idea to use a separate bluez-tools package for them. --disable-cups Disable support for CUPS printer backend By default the printer backend for CUPS is build and also installed. For systems that do not require printing over Bluetooth, this options allows to disable it. When the CUPS backend is selected, it is a good idea to use a separate bluez-cups package for it. --disable-monitor Disable support for the Bluetooth monitor utility By default the monitor utility is enabled. It provides support for HCI level tracing and debugging. For systems that don't require any kind of tracing or debugging capabilities, this options allows to disable it. The monitor utility should be placed in the main package along with the daemons. It is universally useful. --disable-client Disable support for the command line client By default the command line client is enabled and uses the readline library. For specific systems where BlueZ is configured by other means, the command line client can be disabled and the dependency on readline is removed. The client should be placed in the main package along with the daemons. It is universally useful. --disable-systemd Disable integration with systemd By default the integration with systemd is enabled and installed. This gives the best integration into all distributions based on systemd. This option is provided for distributions that do not support systemd. In that case all integration with the init system is up to the package. --disable-a2dp Disable A2DP profile By default bluetoothd supports A2DP profile using a built-in plugin, this option disables it. This option is provided for distributions that do not have any audio capabilities. --disable-avrcp Disable AVRCP profile By default bluetoothd supports AVRCP profile using a built-in plugin, this option disables it. This option is provided for distributions that do not have any audio capabilities. --disable-network Disable PANU, NAP, GN profiles By default bluetoothd supports PANU, NAP and GN profile using a built-in plugin, this option disables it. This option is provided for distributions that do not have any network capabilities. --disable-hid Disable HID profile By default bluetoothd supports HID profile using a built-in plugin, this option disables it. This option is provided for distributions that do not have any input capabilities. --disable-hog Disable HoG profile By default bluetoothd supports HoG profile using a built-in plugin, this option disables it. This option is provided for distributions that do not have any input capabilities. --enable-testing Enable testing tools By default tools used only for testing emulation are disabled. This option can be used to enable them. It is not recommended to enable this option for production systems. These tools may contain tests that depend on specific environment or kernel features in development. --enable-experimental Enable experimental tools By default all tools that are still in development are disabled. This option can be used to enable them. It is not recommended to enable this option for production systems. The behavior of the experimental tools is unstable and might still change. --enable-deprecated Enable deprecated tools By defauld all tools that are no longer maintained are disabled. This option can be used to enable them. It is not recommended to enable this option for production systems. The behavior of the deprecated tools may be unstable or simply don't work anymore. --enable-nfc This option enable NFC pairing support. By default the integration with neard is disabled, this gives the option to enable it in system where neard is supported. The plugin is built into bluetoothd therefore it does not need to be package separately. --enable-sap This option enable SAP profile using sap plugin. By default sap plugin is disabled since it requires tight integration with systems and is very rarely required. The plugin is built into bluetoothd therefore it does not need to be package separately. --enable-health This option enable health profiles. By default health plugin is disabled since its profiles are target for the health industry. The plugin is built into bluetoothd therefore it does not need to be package separately. --enable-midi This option enable MIDI support via ALSA Sequencer. By default midi plugin is disabled since it still considered experimental. When bluetoothd will create a new ALSA Sequencer client and port for each device connected that supports the MIDI GATT primary service. The plugin is built into bluetoothd therefore it does not need to be package separately.
