2. Hardware Features

A description of some of the key features in the BM71-XPro board is provided below. Refer to Figure 1-1 for details of the kit contents.

2.1 Power Supply

Power the BM71-XPro kit using any of the power sources listed below:

• Micro USB port (J1)

• XPro Connector

Use the J2 header for selecting between these power supply options using a jumper. The green LED (LD1) indicates that the board is powered by a micro-USB. The micro-USB has ESD and overcurrent protection, and the input to the module is controlled via an LDO (U1). The BM71-XPro board can be operated in a standalone mode when powered via the micro-USB.

2.2 USB-UART Bridge

The MCP2200 in the BM71-XPro board provides the option to evaluate the BM71 module in Standalone mode. By default (out of the box), the BM71 module is set to operate in Auto mode. So, the module, once powered via the micro-USB, will be able to connect to a peer Bluetooth Low Energy device and open a data pipe for data transfer. Refer to 3.1 Connecting the BM71 XPRO to MBD App in Auto Mode for details. Apart from powering the board, the micro-USB port can also be used to evaluate and test the module via a host PC. Microchip provides emulation tools, such as a UI tool, auto pattern tool, and manual tool (refer to BM71 webpage for details) to evaluate the BM71 via a host PC. The BM71 module can be set to operate in Manual mode for complete control or in Auto mode for a simple data pipe application.

2.4 DIP Switch

The DIP switch has three switches which provide the functions described in the following table.

Table 2-2. DIP Switch Functions

Switch# Function

1 Manually set the BM71 system configuration. Connected to pin P2_0.

• ON: Memory Programming mode

• OFF: Application mode

2 Turn the Blue LED (LD4) ON/OFF

3 Control the GPIO pin P1_3

2.5 Reset Switch

The Reset push button is connected to the BM71 module reset line. When the Reset button is pressed, it drives the reset line to ground. The BM71-XPro board has an on-board voltage detected reset IC (MCP112) connected to the Reset pin of the BM71.

2.6 Current Measurement Header

A J3 header can be used for current measurement.. All power to the BM71-XPro is routed through these header pins. To measure the power consumption of the module, remove the jumper and replace it with an ammeter. To make sure only the power consumption of the BM71 module is measured, turn off the blue LED using switch #2 of the DIP switch.

2.7 On-board SPI Flash

An SST25VF080B SPI Flash memory is included in the BM71-XPro board for nonvolatile firmware storage. This can be used to update the device firmware for the BM71 or the host MCU.

DS50002891A-page 5

BM71-XPro

Hardware Features

Note: BM71 Xplained Pro board is intended for use for development, demonstration or evaluation purposes only. It

is not a finished appliance, nor is it intended for incorporation into or reference design for finished appliances that are made commercially available. Every effort has been made to minimize electromagnetic emissions from the product. However, under certain conditions, the system (this product connected to a host application circuit via Xplained Pro extension header for communicating with External SPI Flash) may emit individual electromagnetic component frequencies which exceed the maximum values allowed by the standards. The frequency and magnitude of the emissions will be determined by several factors, including layout and routing of the application with which the product is used. The recommendation is to add external series resistors on the Xplained Pro Extension Header SPI signals to the External SPI Flash if the product causes emissions above the permissible limits of the standard. For reference for the BM71 module placement and layout guidelines please refer the BM71 Module datasheet.

DS50002891A-page 6

3. Module Configuration

The BM70/71 module supports following modes, which affect the overall Bluetooth Low Energy and hardware behavior:

• Auto operation configuration or Auto mode: By default, the BM70/71 module is set to operate in the Auto

mode. The Auto mode restricts the available Bluetooth Low Energy operations by only allowing the Bluetooth Low Energy peripheral to act as a raw data pipe. This is compatible with hosts who only require the BM70/71 module to act as a virtual UART cable between the host and the remote peer device.

• Manual operation configuration or Manual mode: Manual operation provides the host MCU a lot more control

and functional options over the BM71 Bluetooth Low Energy protocol and operation in comparison to the Auto Operation mode. This configuration is used by a host MCU to leverage the flexibility and feature set offered by both the Bluetooth Low Energy protocol and the BM71 module (for example: private services and characteristics).

Note: For more details, refer to the Section 1.1 Operation Overview in the BM70/71 Bluetooth Low Energy Module User’s Guide (DS50002542).

The simplest method to start evaluating the BM71 is to connect it to a host PC that supports USB CDC virtual COM (serial) ports and operates in Auto mode. In this mode, the user can directly connect to the BM71 from a peer device (phone app) and open a raw data pipe. Refer to 3.1 Connecting the BM71 XPRO to MBD App in Auto Mode for connection procedure. See 3.2 Configuring the BM71 Module to Operate in Manual Mode (Host PC) and 3.3

Connecting the BM71-XPro to MBD App in Manual Mode (Host PC) for an example of Manual mode of operation.

Microchip Devices Code Protection Feature

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.
