Bluetooth is a wireless technology standard. In STB MAG, Bluetooth is used to connect auxiliary devices like audio-devices (portable wireless speakers, headphones, etc.) and  input devices (remote control, keyboard, mouse, etc.).

Bluetooth technology specification for various STB models:

STB model Specification
MAG-349w3 Bluetooth 4.1
MAG-351w3 Bluetooth 4.1
MAG-420w1 Bluetooth 4.1
MAG-424w3 Bluetooth 4.1

Supported Bluetooth profiles and device classes

Bluetooth communication protocol designed in accordance with master/slave architecture. STB acts a role of master and auxiliary devices act as slaves. Every STB with Bluetooth operated can communicate several auxiliary devices (Bluetooth devices) simultaneously.
There are two categories of Bluetooth devices which can connect to STB:

  • Audio devices (A2DP audio streaming profile) - speakers, headphones, smartphone earpiece and other bluetooth audio receivers that are designed to sound audio signal transmitted from from source (for instance, STB) via Bluetooth radio channel. STB acts as transmitter, audio device - as receiver of an uni-directional audio stream. STB can connect one or two audio devices at the same time.
    Note. During audio signal transmitting to Bluetooth channel, it transmits to standard audio ports of STB (HDMI, S / PDIF, A / V) as well.
  • USB HID class devices. This type includes input devices - remote controls, keyboard, mouse, etc. used to configure and manage STB operation. STB supports multiple device connections (several HID devices at the same time).
    Note. STB supports USB connected input devices and Bluetooth USB HID devices simultaneously.

STB can connect Bluetooth-devices of both specified categories at the same time (for example, speakers, keyboard and mouse). If STB is not able to connect particular Bluetooth device (for instance, connected devices limit is exeeded, devices are not compatible, etc.), STB displays 'Connection failure' message while attempting to pair this device.

Example of connecting Bluetooth device

To configure Bluetooth wireless settings on STB go to System Settings Network Bluetooth.

Let's consider the example of connecting new (second) keyboard device Keyboard K380 in case of already connected first device JBL Flip4 speakers.

1.Open System Settings Network Bluetooth.

Image Documentation

2. In Scan device window, find out whether required device is detected. If device to be connected is not found (not in the list):

  • Turn on Bluetooth device and start connecting (pairing) procedure on it, in accordance with the operating instructions of the device.
  • Click on Search for device button in Scan device window or press Update Image Documentation on RC.

3. As a result of searching, required device should be displayed in the list (in the example - Keyboard K380).

4. To start pairing and establish connection on STB side, select required device in the list (in the example - Keyboard K380) and press OK on the remote control. After that STB displays 'Connection'
message. If you agree to connect, press OK.

5. Next, for pairing to keyboard, STB displays 'Bluetooth pairing request' message including a pairing code (set of digits). Enter the pairing code and then press Enter on the keyboard.
Note. Bluetooth devices that are not intended to enter data (speakers, mouses etc.), do not require the identification procedure with pairing code. This type devices should be paired automatically (pairing code is not used).

Image Documentation

6. As a result of the previous steps, STB and Bluetooth device should be connected each other. Bluetooth device is ready for use. In Scan devices window two icons should appear in the string of connected device (in the example - Keyboard K380):

  • Bluetooth Image Documentation - means that STB can interact with the device;
  • Paired Image Documentation - means that this device is paired and appropriate data is stored in STB user data.

Reconnecting

Reconnecting Bluetooth device should be made in case of break down the previously established connection. This situation is detected when device does not interact with STB. It is usually indicated In Scan devices window with Bluetooth Image Documentation icon disapearing but Paired Image Documentation icon still displaying for this device. After Reconnecting Bluetooth Image Documentation icon is displayed again in string of this device.
Reconnection is performed as follows:

  • on connected device - turn on and start Bluetooth connection;
  • on STB - start Bluetooth connection to this device (see Example, step 4).

Typically, reconnection is necessary in the neхt cases:

  • after STB is rebooted;

  • after leaving Standby mode of STB;

  • after disabling Bluetooth on the STB side;

  • after disabling Bluetooth on the device side or if the device was turned off.

Note. If reconnection is unsuccessful, Unpaire procedure should be performed and then this device should be connected from the beginning (see Example).

If STB detects Bluetooth connection losing (for example, the keyboard is turned off), Bluetooth Image Documentation icon disappears from Scan devices window. After device successful reconnecting, two icons should become displayed: Bluetooth Image Documentation and Paired Image Documentation in appropriate string.

Unpaire Bluetooth device

In order to disconnect certain device from STB and exclude it from Scan device list, you must select this device in the list and press Unpaire (F2 on remote control).

Note. All paired devices Information clears after Clear user data command activation.

Disable / Enable Bluetooth on STB

Temporarily disabling of Bluetooth operation on STB can be performed if needed. You must click on Disable Bluetooth (F1 on RC) to disable Bluetooth support. Use Enable Bluetooth shortcut (or F1 on RC) to resume Bluetooth support. These commands turns off / turns on Bluetooth hardware module on STB.

After Bluetooth enabling on STB, you need to reconnect the devices.
