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 “SW9” in “Off / Off / On” state make .system in application mode. 2. Connect the speaker line to the amplifier output connector (J6 / 7). 2.2.2 USING THE EVALUATION BOARD 1. Connect 15V adapter P2. 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. Go to the previous track. 2015 Microchip Technology Inc. Preliminary Edition page 10 BM23 BLUETOOTH EVALUTATION BOARD USER’S GUIDE Go to the next track. Start / stop playing the current track. FIGURE 1-2: BM23 EVALUATION BOARD AUDIO CONTROL BUTTONS 2015 Microchip Technology Inc. Preliminary Edition page 11 BM23 BLUETOOTH EVALUTATION BOARD USER’S GUIDE 2.3.2 HSP/HFP DEMONSTRATION In this demonstration, user can explore the hands-free profile setting to receive an incoming voice call from a paired smartphone. This demonstration requires a microphone. It would be good to use a PC headset/microphone (with two-plugs). The following are the steps to perform the demonstration. 1. Connect the speakers / microphone to BM23 evaluation board’s audio out connector (J6/7) and MIC input (P6) respectively. 2. Connect BM23 evaluation board to a smartphone that supports the A2DP and HFP/HSP Bluetooth profiles. 3. From another one phone, initiate a call to the smartphone that is paired with BM23 evaluation board. The A2DP stream pauses and the ringtone plays on the speakers. 4. Click button “MFB” on BM23 evaluation board to accept the incoming call. 2015 Microchip Technology Inc.
