2. Getting Started
2.1 INTRODUCTION
This chapter describes how the BM20 Evaluation Board works. Certain hardware and utilities are essential to
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
“SW12” in “Off / Off / On” state make .system in application mode.
2. Connect the portable mini-speaker 3.5 mm to the stereo audio out connector (P6).
2.2.2 USING THE EVALUATION BOARD
1. Connect Li-Ion batteries to JP20 or JP19.
2. Click MFB button to turn-on and enter pairing mode. The status LEDs will blink. Now the BM20 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. The board display as
“EDDY SHS”.
4. If the pairing with the device is successful, BM20 evaluation board can connect to the host device. Once
connected, BM20 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 BM20 evaluation boards using a computer or
smartphone. The following are the steps to perform the demonstration.
1. Connect BM20 evaluation board to a host device (PC or smartphone) that has an audio source.
2. Connect headphones (or mini-speakers) to BM20 evaluation board P6.
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 BM20 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.

Go to the previous track.
