3.2 GETTING STARTED WITH THE BM62 EVB
To establish a Bluetooth connection between the BM62 EVB and a host device,
perform the following actions:
1. Set switch SW12 to Application mode, as illustrated in
Figure 3-1 .
FIGURE 3-1: SW12 IN APPLICATION MODE
2. Connect a speaker to the audio output connector (J3 and J4) of the BM62 EVB.
3. Connect the BM62 EVB to a PC through a micro-USB cable for the power supply.
LED2 (red) will turn on.
4. On the BM62 EVB, long press the MFB button to turn on the Bluetooth. Both
LED1 (blue) and LED2 (red) will blink together. Then, continue to press the MFB
button (approximately 5 seconds) until both the LEDs blink alternately. This LED
behavior indicates that the BM62 EVB is in discoverable mode.
5. Turn on the Bluetooth on a host device (PC or smartphone), and it will display a
list of discoverable Bluetooth devices. The BM62 EVB is displayed as
“Dual_SPK” or “LE_Dual_SPK”. Select the device to establish the connection.
6. LED1 (blue) will blink faster, and it indicates that the BM62 EVB is paired with the
host device.
7. Once the connection is established, LED1 (blue) will blink twice at regular inter-
vals. It will display as “connected” in the Bluetooth settings of the smartphone.
With the default settings, the BM62 Stereo Audio module enables Advanced
Audio Distribution Profile (A2DP) for audio playback and Audio Video Remote
Control Profile (AVRCP) for player control.
3.3 APPLICATION DEMONSTRATION
3.3.1 Speaker Audio Demonstration
In this demonstration, the user can stream audio on the BM62 EVB using a host device
(PC or smartphone). Perform the following actions for the audio demonstration. Refer
to
Figure 3-2 .
1. Establish the connection between the BM62 EVB and a host device, using the
procedure listed in 3.2 “Getting Started with the BM62 EVB” .
2. Once the connection between the BM62 EVB and the host device is established,
open the audio source on the host device. Microchip recommends using a media
player (for example, Windows Media Player, iTunes
®
, or Android).
3. Start the audio stream on the media player. Both LED1 (blue) and LED2 (red) will
blink once at regular intervals during the audio playback.
Note: The user can also power the board by connecting a Li-Ion battery to JP19
or JP20 on the BM62 EVB.
Note: “Dual_SPK” is used for Bluetooth classic and “LE_Dual_SPK” is used for
BLE devices.
