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-424w3 Bluetooth 4.2

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 earpieces, and other Bluetooth audio receivers that are designed to sound audio signals transmitted from source (for instance, STB) via Bluetooth radio channel. STB acts as the transmitter, whereas an audio device as receiver of the uni-directional audio stream. STB can connect one or two audio devices at the same time.
    Note. During audio signal transmitting to the 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 a particular Bluetooth device (for instance, connected devices limit is exceeded, devices are not compatible, etc.), STB displays the 'Connection failure' message when 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 a new (second) keyboard device Keyboard K380 in the case of the already connected first device JBL Flip4 speakers.

1.Open System Settings Network Bluetooth.

Image Documentation

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

  • Turn on the 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 the Scan device window or press Update keyImage Documentation on RC.

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

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

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

Image Documentation

6. As a result of the previous steps, STB and the Bluetooth device should be connected to each other. The 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 Bluetooth device should be made in case of break down the previously established connection. This situation is detected when the device does not interact with STB. It is usually indicated In the Scan devices window with Bluetooth Image Documentation icon disappearing but Paired Image Documentation icon still displaying for this device. After Reconnecting Bluetooth Image Documentation icon is displayed again in the string of this device.
Reconnection is performed as follows:

  • on a 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 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, the Unpair 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 the Scan devices window. After the device successfully reconnecting, two icons should become displayed: Bluetooth Image Documentation and Paired Image Documentation in an appropriate string.

Unpair Bluetooth device

To disconnect a Bluetooth device from STB and exclude it from the Scan device list, you must select this device in the list and press Unpair (F2 on RC).

Note. All paired device information is erased 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 turn off / turn on the Bluetooth hardware module on STB.

After Bluetooth is enabled on STB, the devices should be reconnected.
