The purpose of this page is to:

• Introduce the Bluetooth technology.
• Document the Linux Bluetooth stack BlueZ.
• Document Bluetooth on Tizen Common.

Jan 14, 2015 According to Tizen Experts, Samsung’s first Tizen OS smartphone, the Z1, will launch with Open Mobile ACL android apps support. This means it will be able to run Android apps. This feat is said to be made possible using Open Mobile’s ACL Technology, which has tens of thousands of Android Apps as part of its catalogue. Download acl for tizen free download. WebDAV CGI WebDAV CGI brings your file service to the Web and is moved to github https://github.com/DanRohde/.

1. Here was a thread compairing Tizen with Sailfish some time ago. If I remember correctly Tizen can NOT use apk like we can in Sailfish it seems like they need to be at least repacked if not re-compiled. I think it was because ACL works this way, but I could be wrong.
2. .Enable your Android apps on the Tizen platform with OpenMobile Application Compatibility Layer (ACL™). With our ACL technology, your Android apps can run seamlessly alongside native Tizen and web apps on any Tizen platform.Getting started is easy, as ACL allows Android apps to execute on the millions of Tizen devices.

Bluetooth is a wireless technology standard for exchanging data over short distances.

• Official Bluetooth website: https://www.bluetooth.org
• Bluetooth specifications download page: https://www.bluetooth.org/en-us/specification/adopted-specifications
• Wikipedia page on Bluetooth: https://en.wikipedia.org/wiki/Bluetooth

Profiles

The Bluetooth technology works with profiles. Profiles define standards to deliver a large choice of services. Profiles use Bluetooth protocols and some profiles even require other profiles.

• Wikipedia page on Bluetooth profiles: https://en.wikipedia.org/wiki/Bluetooth_profile

BlueZ is the name of the official Bluetooth stack on Linux. It implements the Bluetooth 4.0 Core specification and supports a large choice of profiles (see the Supported profiles section for a complete list) .

Tizen Store Apk

BlueZ official website: bluez.org

Bluetooth agent

Bluetooth connections are generally managed through a Bluetooth agent whose role is to automatically configure and chose the right options to manage Bluetooth connections leaving the user the tasks to chose the devices to connect/disconnect to and enter PIN codes.

The CLI client bluetoothctl come with its own agent but can also use a different one. BlueZ also provides an external Bluetooth agent called simple-agent.

Supported profiles and protocols

Here is a list of all existing profiles and protocols with the ones supported in BlueZ. Note that you can find the complete, updated list of supported profiles and their versions in the file doc/supported-features.txt from the bluez package. Also some profiles/roles depend on external components such as oFono or ConnMan.

• List of adopted specifications (lists all profiles and protocols): https://www.bluetooth.org/en-us/specification/adopted-specifications

BlueZ CLI clients

The BlueZ project provides several CLI clients allowing users to use some of the supported profiles.

bluetooth-player

Allow the user to remotely control media players through he AVRCP profile.

Use example

bluetoothctl

CLI client to manage connections between devices. It includes a default bluetooth-agent.

Use example:

Due to https://bugs.tizen.org/jira/browse/TC-1511, 'power on' fails with 'org.bluez.Error.Blocked' and journalctl reports 'Operation not possible due to RF-kill'. As a workaround, install connman-test, run 'connmanctl' as root, and enter 'enable bluetooth'.

obexctl

CLI client for the FTP profile that manages file transfer and browsing over Bluetooth.

Usage :

BlueZ test tools

This section introduces some of the Bluetooth test tools from the BlueZ project. Those tools are mostly made for development and debugging purposes.

btmon

Bluetooth monitor - Display all HCI commands and events in a human readable format (and with color !). Can dump data in with the btsnoop format.

Note that this format is now supported by Wireshark (1.11.x). Also supported by development libpcap for realtime capturing.

hciconfig

hciconfig is used to configure Bluetooth devices.hciX is the name of a Bluetooth device installed in the system (ie., hci0).

Display Basic Info About Available Bluetooth Devices:

Display Info About A Specific Bluetooth Device:

UP or DOWN A Bluetooth Device Manually:

hcidump

Dump all HCI events and commands

Realize a dump file readable with Wireshark

hcitool

hcitool provides a simplified way of sending commands to the HCI device.

To launch an arbitrary command not present in the command list the command 'cmd' can be used.

For example:

sets the PIN type as fixed. For more details about the commands values, please refer to the Bluetooth Core Specification V.4.1 (https://www.bluetooth.org/DocMan/handlers/DownloadDoc.ashx?doc_id=282159).

list-devices

List paired devices and information about them for all available Bluetooth controllers.

l2ping

Bluetooth layer 2 ping.

mpris-player

Tool to test AVRCP on the player/receiver side.

This tool uses the MPRIS specification which defines a standard way to control media players.

MPRIS specification: http://specifications.freedesktop.org/mpris-spec/latest/

sdptool

sdptool provides the interface for performing SDP queries on Bluetooth devices, and administering a local SDP database called sdpd.

Usage:

The search results can be viewed in three formats XML, RAW and TREE. It also provides option to add/del/get local service.

test-manager

Simple tool that displays available Bluetooth adapters.

External test tools

Wireshark

Network analyser with a GUI. Can analyze Bluetooth frames.

You can open a capture file made with the command 'hcidump -R -w <dest_file>' or 'btmon' with Wireshark.

Wireshark wiki page on Bluetooth: http://wiki.wireshark.org/Bluetooth

Tshark

CLI network analyser. Has the same features as Wireshark.

Using Bluetooth

Connecting devices

The simplest ans easiest way to connect to a device on Tizen is to use the bluetoothctl tool.

A2DP

To connect to and use an A2DP device an A2DP sink or source is required. PulseAudio provides such features. Make sure that PulseAudio is running before attempting a Bluetooth connection otherwise you won't be advertising for A2DP support which will lead in a connection failure with some devices like Bluetooth headsets.

Note that PulseAudio requires the module 'module-bluetooth-discover' to be loaded in order to get A2DP working. You can either:

• Launch it at the same time as PulseAudio

• Load it while PulseAudio is working (not tested)

• Get it automatically loaded at PulseAudio launch by adding a few lines in its configuration file (called default.pa by default and generally located in /etc/pulse/). Note that those lines are already present in the default configuration file.

Reference / Links

AVRCP

If the AVRCP profile is supported by the remote device, the remote control feature should automatically work once the two devices are connected. Note that AVRCP requires the A2DP profile.

To test the AVRCP profile on the receiver side use the mpris-player test-tool.

To test the AVRCP profile on the controller side use the bluetooth-player CLI client.

Reference / Links

HID

Connecting a mouse or a keyboard

Getting a wireless mouse or keyboard to work on Tizen should be pretty straightforward since the only thing to do is to establish the Bluetooth connection.

Using Bluetoothctl

bluetoothctl might ask you to enter a PIN code; if so, just enter '0000' which is the default PIN code generally used by devices without display and keyboard.

Note that Bluetooth features are only supported on reference target devices, not on the SDK Emulator.
Specification for Tizen mobile :

{ Mobile device implementations SHOULD implement the Audio/Video Remote Control Profile(AVRCP) and the Object Exchange (OBEX) protocol.}
