Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.

3.2
GETTING STARTED WITH BM64 EVB
The BM64 EVB is preprogrammed with dual-mode software where Advanced Audio
Distribution Profile (A2DP) and Bluetooth Low Energy (BLE) can be operated simultaneously. The MCU (PIC18F85J10, U13) on the BM64 EVB is also preprogrammed to
work with dual-mode software. To establish the Bluetooth connection between the
BM64 EVB and a host device, perform the following actions:
1. Set switch SW9 to Flash Application mode, see Figure 3-1.
FIGURE 3-1:
SW9 IN FLASH APPLICATION MODE
2. Connect the speaker line to the amplifier output connector (CN1 and CN2).
3. Connect the 15V DC power adapter to P2, as illustrated in Figure 3-2.
Note:
Do not plug-in the USB cable.
FIGURE 3-2:
DS50002514B - Page 24
USING THE EVALUATION BOARD
2016-2018 Microchip Technology Inc.
Getting Started
4. Figure 3-3 illustrates the various push buttons on the BM64 EVB. Long press
SW24 (MFB) (approximately 5 seconds) to turn the Bluetooth on. Both LED1
(blue) and LED2 (red) will blink together, and later only LED1 (blue) will blink
once at regular intervals.
5. Long press SW40 (pairing key) to enter pairing mode (depending on the UART
command settings from the MCU to the Bluetooth module). LED1 (blue) and
LED2 (red) will blink alternatively to indicate that the BM64 EVB is in
discoverable mode.
FIGURE 3-3:
SW24 AND SW40
6. Turn on the Bluetooth on a host device (PC or smartphone) and it will display a
list of discoverable Bluetooth devices. The BM64 EVB is displayed as
“Dual_SPK” or “LE_Dual_SPK”. Select the device to establish the connection.
Note:
The “Dual_SPK” is used for the Bluetooth classic, and the “LE_Dual_SPK”
is used for the BLE devices.
7. The LED1 (blue) blinks faster. This indicates the BM64 EVB is paired with the
host device.
8. Once the connection is established, LED1 (blue) will blink twice at regular intervals. It will display as “connected” in the Bluetooth settings of the smartphone.
With the default settings, the BM64 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
Audio Demonstration
In this demonstration, the user can stream audio on the BM64 EVB using a host device
(PC or smartphone). Perform the following actions for the audio demonstration, refer to
Figure 3-4.
1. Establish the connection between the BM64 EVB and a host device using the
procedure listed in 3.2 “Getting Started with BM64 EVB”.
2. Once the connection between the BM64 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®, and Android™).

BM64 EVB User’s Guide
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.The audio control
buttons are used for these functions:
- To control the audio output volume (long press VOL+ or VOL- button)
- Go to the previous track (short press > button)
- Start/stop playing the current track (short press PLAY/PAUSE button)

HSP/HFP Demonstration
In this demonstration, the user can explore the Headset Profile (HSP) or Hands-Free
Profile (HFP) setting to receive an incoming voice call from a paired smartphone. Perform the following steps for demonstration, refer to Figure 3-4.
1. Establish the connection between the BM64 EVB and a host device using the
procedure listed in 3.2 “Getting Started with BM64 EVB”.
2. Connect the speaker to the audio out connector (CN1 and CN2) and a microphone to the MIC input (P6), respectively, on the BM64 EVB.
3. Initiate a call from another phone to the smartphone that is paired with the BM64
EVB. The A2DP stream pauses and the ringtone is played on the speaker. LED1
(blue) blinks three times at regular intervals.
4. Press the SW24 (MFB) button on the BM64 EVB to accept the incoming call.
LED1 (blue) and LED2 (red) will blink three times at regular intervals.

CONFIGURING BM64 MODULE
The BM64 EVB can be configured and various parameters can be customized using
the UI tool and DSP tool, and then parameters are saved in a file. Using the MPET tool,
the saved files are merged into the *.ipf file, and then this merged file is programmed
into the EEPROM. After EEPROM is programmed, restart the device to see the effect
of the customized parameters.
3.4.1
UI Tool Configuration
The User Interface (UI) tool is a configuration tool which enables the user to change
the BM64 module parameters, such as device name, enable/disable pairing mode,
BLE connection settings, configure the LEDs and enable/disable battery functions.
To configure the UI parameters, perform the following actions:
1. Open the UI configuration tool and click OK to configure the UI parameters, see
Figure 3-5.
Note:
Download and install the UI tool, which is available on the Microchip web
site: www.microchip.com/BM64. For this demonstration
