1. Overview
This document describes the hardware and software for the ISSC BM77EVB evaluation kit.
The BM77EVB allows the designer to evaluate and demonstrate the capabilities of the ISSC BM77 Dual Mode
Bluetooth RF Module. The evaluation board includes an integrated configuration and programming interface for
plug-and-play capability. It also includes on-board connection and data status LEDs enabling rapid prototyping and
fast time to market.
In addition to BM77EVB hardware, several software applications are provided to demonstrate Bluetooth data
connections to the onboard BM77 module. The demonstration software consists:

Android Chat Application (SPP)

iOS Bluetooth Terminal (BLETR)

BT Chat Tool
1.1. BM77EVB Description
BM77EVB provides rapid prototyping and developing for Bluetooth data applications for Classic SPP or Bluetooth
Low Energy. It can be powered via USB host or external battery Li-Battery. The BM77EVB utilizes the BM77 module,
a fully certified Bluetooth 4.0 dual mode RF module supporting Bluetooth Classic SPP (Serial Port Profile) and
Bluetooth Low Energy (BTLE) – providing a Bluetooth serial data connections. The BM77EVB provides a USB
UART converter allowing flexible interface to host PC, a PC terminal utility and SmartPhone APPs to drive both
classic SPP and BTLE data connections.

4. Quick Start Guide to Using the BM77EVB
The following sections describe how to establish Bluetooth serial data connections using the BM77EVB. The
purpose of the exercise is to demonstrate the basic data capabilities of the BM77EVB, and interoperability with other
Bluetooth devices. Please note that in all these demonstrations, the BM77EVB is a Bluetooth slave waiting for a
connection initiated by the Bluetooth master device.
For this demonstration, the following hardware and software is required:
Required Hardware:

BM77EVB Evaluation Kit, p/n EV77SPPS3MC2A available on www.microchipdirect.com

Bluetooth enabled Smartphone or Tablet

o
Android device running Android 4.3 or later
o
iOS: iPhone 4S or later, iPad3 or later, must support Bluetooth Low Energy
Windows Host PC with USB port
Required Software:
The software applications needed to demonstrate the BM77EVB is show below:

BT Chat Tool, “BT Chat v004.exe” available at www.microchip.com/BM77

Android Chat Tool, “BTChat_V1.0.3.apk” available www.microchip.com/BM77

iOS Terminal “BLETR”, available on Apple AppStore™

MCP2200 driver for Windows, available at www.microchip.com/MCP2200
4.1. Bluetooth SPP connection to Android Smartphone/Tablet
In this demonstration a Bluetooth (SPP) data connection will be established between the BT Chat Tool, across
BM77EVB to the Smartphone application. For the SPP demonstration an Android 4.3 or later smartphone or
tablet is required.
As illustrated below, the host PC runs a BT Chat Tool application, which transfers serial data over a COM port (USB
virtual COM port) to BM77EVB, where it is transmitted over a Bluetooth connection to the remote Bluetooth host,
which is this example is a Smartphone application.

Step 1. Verify JP2 is configured for USB power.
Default is using USB as the main power supply.
Step 2. Verify SW1 switches are set to Application mode.
Make sure the SW1 is under the Application Mode. 1: OFF, 2: OFF, 3: OFF
Step 3. Verify SW5 button is in the ON (pushed down).
Step 4. Using the micro USB cable, connect the BM77EVB to host PC USB port to power up EVB.
The blue connection LED1 indicates connection state as follows:
Stand-by State- the LED1 of EVB will blink once at a time. (Blue)
Pairing, Connected State- the LED01 will blink twice at a time.
Step 5. Verify Virtual COM port is created
If a virtual COM is not observed in the Device Manager port list, it may be necessary to install Microchip
MCP2200 driver. (Search Internet by typing keyword” Microchip MCP2200 Driver”)
Step 6. Run the BT Chat Tool.exe on your PC and make sure the COM Port is connected.

4.2. Bluetooth Low Energy Data Connection to iOS Device
This demonstration show how serial data is transmitted from BM77EVB (via PC Chat) to an iOS device using
Bluetooth Low Energy connection. This demonstration uses ISSC BLETR APP to connection to the BM77EVB.
Bluetooth Low Energy is utilized since iOS devices do not support Bluetooth Classic SPP data connections. A key
feature of the BM77 is transparent serial data connection from BM77 UART to an iOS device.
a. Using an iPhone 4S or later, iPad3 or later device, download and install “ISSC BLETR” APP. As illustrated
below, the BLETR App is available on the AppStore.
© 2014 ISSC Technologies Corp.
17
b. Turn on the Bluetooth radio in iPhone, iPod or iPad Settings application.
c. Go to Settings/ General/ Bluetooth Page.
d. Turn ON the Bluetooth.
e. Launch the iSSC BLETR APP and it will scan the Bluetooth Low Energy Peripheral devices and list them. If
the device does not appear press the “Refresh” button to restart the BTLE peripheral scan. Find the
Dual-SPP BTLE peripheral device. Select it to start a connection to the BM77EVB named Dual-SPP.
f. After a successful connection to BM77EVB, BLETR will display the device as connected as shown below.

18
g. Select the connected Dual-SPP device to display the top level view. This view presents three options when
connected to a BM77EVB.
Transparent - View to display received data, send data, and enable features
Proprietary- This view sets Bluetooth Low Energy connection parameters
Device Info -This view displays the settings for Bluetooth Low Energy Device Information Service
© 2014 ISSC Technologies Corp.
19
h. Selecting “Transparent” button opens the transparent Serial Data view as shown below. The default mode is
Raw (ASCII) mode where any data characters received are displayed in the large text box in red font.
Data Mode Transfer

20
To send data from BLETR iOS device to the BM77, select the input text box. The soft keyboard will be displayed as
shown below. Enter text in the input text box. Click “Send” button to transmit text to BM77.
After clicking “Send” the text is received via the BM77 UART and displayed in the BT CHAT text window.

21
Timer Feature
In addition to Raw mode (ASCII) the Transparent data view also has Timer and Echo features. The Timer feature
allows the BLETR to send a repeated test pattern to BT CHAT for test throughput and data transfer test.
An example of the “Timer” test feature is shown below.
BLETR configured to transmit a 100 test blocks of 20 characters, every 1000ms. BT CHAT tool receives the test
pattern data and displays it in red text. The line break indicates a Bluetooth Low Energy packet break, meaning a
transmittted test block was fragmented into multiple BLE packets.
Clicking the “Start” button initiates the data transfer.

22
Tx File Feature
Another test feature similar to the Timer feature is the “TX File” transfer. The “TX File” functions transfers files, which
as embedded in the BLETR APP, to the BM77. The steps to use this feature are as follows:
a. Click the “TX File” button to open a dialog with list of file sizes to transmit
b. Select the file size to send
c. Observe the file received on BT Chat.

23
Echo Feature
The Echo feature is an optional function for the Transparent data view. When Echo is enabled, any data received by
BLETR is echoed back to sender.
The example below show text sent from BTCHAT being echoed to BLETR when the Echo mode is enabled.

24
Device Information Feature
The Device Information view displays the characteristics associated with Device Information service. The Device
Information service is available to all Bluetooth 4.0 low energy host that access the BM77EVB. It exposes the
information identifying information about the BM77 peripheral device. These values can be programmed using a
configuration tool described in the application note.
© 2014 ISSC Technologies Corp.
25
Proprietary (Configuration) Feature
The Proprietary view demonstrates the capability to change Bluetooth Low Energy connection parameters remotely
via BLETR application. These parameters only affect Bluetooth Low Energy connections.
1. Max Interval: time (ms) between communication interval between BM77 and Bluetooth LE Central device.
2. Connection Timeout: time (ms) between communication events before a connections considered lost
3. Latency: Number of connection events peripheral (BM77) is allowed to skip
4. Bluetooth LE Name used to advertise Peripheral name to scanning Central devices. Enter new name in text
box and click “Change Name” to invoke change.
