How to use the board

The board is simple to set up and use. Just connect the power supply to the supply wires

ensuring that the red wire is 3.3 V and the black is 0 V (ground).

Connect a suitable amplifier with speakers or headphones, if desired, to the line output.

The board can communicate to any of the tested A2DP BT sources given in Section 5:

Interoperability on page 12.

Turn on the transmitter and source equipment and the BT-HTS_RX board. When the power

to the board is turned on the blue LED (D1) turns on for a short time indicating the

initialization of the board. After the LED extinguishes the board is ready to operate.

Now follow this procedure.

in its neighborhood.

2.

Find this demo board in the list of the discovered devices: the demo board appears with

its name (HTS_RX) and/or its address (00:80:E1:00:01:00).

3.

Select it and choose the “pair” option.

4.

Enter the code “0000” to pair the source and the receiver. D1 again turns on with a

controlling the devices.

Figure 8 refers to points 2, 3 and 4 above. Here you can see all of the discovered devices.

On selecting the HTS_RX demo board, its BD address appears on the left bottom of the

main window. The smaller pop-up window asks for the pairing code related to the board.

Pairing is accomplished as soon as the code “0000” is confirmed, then the refreshing of the

available services highlights the AV service. The BT-HTS-RX audio receiver board indicates

a successful connection by turning on the blue LED after pairing.

Figure 9 shows the window during audio streaming that begins once that service is

launched.

In this kind of test extra software for playing the audio is required (for example, Windows

Of course, actual needs are related to the source used for the BT connection. For instance,

the portable MP3 players and mobile phones that are compliant to this standard already

incorporate all of the necessary items. Refer to the specific source product for further
