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.

BLEDK3 AUTO PATTERN AND MANUAL PATTERN TOOLS
The BLEDK3 firmware, written on the BM70 module, has two distinct modes, Auto Pattern and Manual Pattern. Both these modes use their own state machines. The BM70
module can be operated in both the modes by setting the value in the EEPROM. By
default, the BM70 module is in Auto Pattern mode.
3.4.1
Auto Pattern Mode
In Auto pattern mode, the state machine automates most of the Bluetooth related operations, such as advertising and Transparent UART service. The Transparent UART
service is primarily used to connect the module to a peer device and to create a data
pipe with the peer device through the Transparent UART mode with minimal instructions from the host MCU.
To evaluate and test the BM70 module in Auto Pattern mode, download and install the
Auto Pattern tool (Windows-based GUI emulation tool), which is available for download
at Microchip web site. This tool implements the communication protocol and provides
a fast and easy way to test the functions with the available options in the Auto Pattern
mode.
3.4.2
Manual Pattern Mode
The Manual Pattern mode provides a full control of the BM70 module to the user and
the module operates only based on the commands from the user or host MCU. The
Manual Pattern tool also allows the Transparent UART mode; however, there is a small
difference in the protocol used in this mode in comparison to the Auto Pattern mode.
To evaluate and test the BM70 module in Manual Pattern mode, download and install
the Manual Pattern tool (Windows-based GUI emulation tool), which is available for
download at Microchip web site. This tool implements the communication protocol and
provides a fast and easy way to test the functions with the available options in the Manual Pattern mode.
Note:
3.5
For more information on Auto Pattern and Manual Pattern tools, refer to the
“IS187x_BM7x BLEDK3 Application Note”, which is available at Microchip
web site: www.microchip. com/bm-70-pictail.
APPLICATION FIRMWARE INFORMATION
The BLEDK3 firmware application is the default application on the BM70 EVB. This
application provides the BLE UART Transparent, BLE GATT-based transceiver, Beacon and BeaconThings functionality.
For additional information on the BLEDK3 application functionality, refer to the
“IS187x_BM7x BLEDK3 Application Note”, which is available at Microchip web site:

Chapter 5. USB-to-UART Converter and Host DUT
This chapter describes the use of the USB-to-UART converter circuit which is available
on the BM70 EVB. The UART interface of the BM70 module on the BM70 EVB can be
connected to the user DUT. The DUT can be a customer board with a host
microcontroller or another BM70 EVB.
5.1
CONNECTING UART TO BM70 EVB DUT
The BM70 EVB has a MCP2200 IC acting as a USB-to-UART converter that connects
the BM70 module to the micro-USB port. The BM70 EVB also has a range of header
pins that connect to the UART I/O pins of the BM70 module. This gives the flexibility to
connect the USB-to-UART converter on the BM70 EVB to another BM70 DUT, or
connect the BM70 EVB test pins directly to another host microcontroller DUT.
Figure 5-1 illustrates how to connect the USB-to-UART converter on the BM70 EVB to
the user BM70 DUT. The pins, HCI_TXD, HCI_RXD, P2_0, VBAT, GPIO and GND, are
connected to the DUT. The user can connect a micro-USB cable to a PC and perform
the emulation tool functions, such as firmware or UI update. The P2_0 pin is connected
to the switch SW7 to switch between Application and Test modes.

CONNECTING UART TO HOST MICROCONTROLLER DUT
Figure 5-2 illustrates how to connect a user microcontroller DUT to a BM70 EVB to perform the emulation tool function. The pins, HCI_TXD, HCI_RXD, P2_0, VBAT, RESET,
GPIO, and GND, are connected to the DUT. In this connection, the microcontroller can
communicate with the BM70 EVB through the HCI UART interface by a defined command set. The P2_0 pin is controlled by the MCU to switch between Application and
Test modes.
