support the evaluation/development of demo applications. This chapter discusses the following topics:
Hardware Requirements
Software/Utility Requirements
Module Configuration
2.2 HARDWARE REQUIREMENTS
2.2.1 HARDWARE SETUP
To setup the evaluation hardware, perform the following steps:
1. Make sure pin 1 / 2 / 3 of
“SW9” in “Off / Off / On” state make .system in application mode.

2. Click MFB button to turn-on and enter pairing mode. The status LEDs will blink. Now the BM23 Evaluation
board should be discoverable.
3. Turn on Bluetooth device manager on a host device (PC or smartphone), the host device will display a list
of discoverable Bluetooth devices. Select the device and connect with it.
4. If the pairing with the device is successful, BM23 evaluation board can connect to the host device. Once
connected, BM23 evaluation board enables Advanced Audio Distribution Profile (A2DP) for audio
playback and Audio Video Remote Control Profile (AVRCP) for player control.
2.3 APPLICATION DEMONSTRATION
2.3.1 AUDIO DEMONSTRATION
In this demonstration, user can play an audio stream on both BM23 evaluation boards using a computer or
smartphone. The following are the steps to perform the demonstration.
1. Connect BM23 evaluation board to a host device (PC or smartphone) that has an audio source.
2. Connect speakers to BM23 evaluation board J6 / 7.
3. Open the audio source on the host device. Microchip recommends using media player.(e.g. Microsoft
Media Player, iTunes, and Android).
4. Start the audio stream on the media player.
When BM23 evaluation board is connected to an audio source compatible with Bluetooth AVRCP, the audio
control buttons are use to:
Control the volume of audio output.
