4.2 Demo Application

This section provides a description of how to use the demo application to connect an audio sink to it and communicate over Bluetooth.

Connecting with a Bluetooth Speaker
Device 2 (Sink) setup
  1. Before we turn on the Source Board, we make sure that the Sink is ready to connect. In our example, we use a Bluetooth Speaker.

  2. Turn on the speaker using the On/Off Switch. You should hear an audible beep.
  3. Hold the mode button until you hear an audible beep and the blue led is flashing. The device is now discoverable and ready to be paired.
Device 1 (Source) setup on the demo application
  1. Make sure that a microphone or similar device is connected to J39. Once the FTDI/microUSB cable is connected, press reset and you should see output similar to the Terminal output above.

  2. The Source device will begin auto connecting with any discoverable & connectable sink device and filter out other devices.

    Note: The device will automatically begin an inquiry/open a sink. If you need to do this manually, follow the steps and reference the Terminal Output below.
    1. Type Inquiry to begin scanning for nearby devices.
    2. Type OpenSink <Inquiry Number> to open a sink channel to a Bluetooth device found during the previous inquiry.

  3. Depending on the settings of the speaker device, it may initiate pairing as well.

  4. The device will finish the connection and you should see a Stream State Change Confirmation and AUD Remote Control Open Indication events.
  5. You can now transmit audio from the source device. Speak something through the mic and the speakers should play the output.

Connecting with the BT-MSP-AUDSNK board
Device 2 (Sink) setup
  1. Make sure that the profile is flashed and the device is powered up and the speakers are connected.

Device 1 (Source) Setup
  1. Setup the device as shown in the previous section. The device should automatically perform an inquiry scan, pair and connect with the SNK board. The images below show the terminal (SNK on the left, SRC on the right) output of both of the devices.
