Chapter 1 overview of Ble-Nano
1.1 Introduct
Ble - Nano bluetooth 4.0 protocol is based on perfect combination Arduino Nano by emakefun to create
customer research and development of a revolutionary product, function and the pin is fully compatible with
traditional Arduino Nano motherboard, scope of work frequency of 2.4 GHZ, modulation mode for the
GFSK, maximum transmitted power of 0 db, the largest launch distance of 50 meters, USES the import
original TI CC2540 chip design, support user through AT commands to modify to check the device name,
service UUID, transmission power, such as matching password instructions, convenient use and flexible.The
size of the product is very small, suitable for many applications where there are severe restrictions on the
size.
We provide Android and IOS mobile phone demo, you can quickly develop a communication with the
phone hardware device.Just like the popular wearable mobile phone peripheral devices, all of them can be
developed with the Ble Nano platform. You can connect the Ble Nano with the bluetooth 4.0 device, realize
the wireless transmission between the two bluetooth devices, and set the master and slave.Even establish
bluetooth HID connection with PC.AT the same time, we provide developers with a great degree of freedom
and support, the user can not only by the AT command debugging Ble - Nano, you can also add on Ble -
Nano controller Arduino compatible extension board, sensor, motor and servo drive, emakefun exclusive
research and development of bluetooth host mode automatic connection from the machine function, and
support for more than 20 bytes to send, it is more convenient to use.

When the bluetooth is not connected, the blue light will flicker, and the blue light will always
be on
The green light flashes when the module communicates with other bluetooth data, or when usb
has data, or when ATmega328P sends serial data

the USB light will be on. If only the power light is on after connecting the USB cable, but the USB
indicator light is not on, it means that the usb-micro cable is broken, please replace it
Chapter 2 drive installation preparation
2.1 Ble-Nano driver install
1) Right-Click “Computer”“attribute”“Device manager”check“port（COM&LT）”，
If you look at this figure 1.1
Figure 1.1 Drive the successful installation interface
2) The driver has been installed successfully. Then we open the IDE and select the corresponding
development board model and port in the toolbar. If it appears as shown in figure 1.2, the computer
does not recognize the development board and needs to install the driver.

2.2 Ble-Nano downloads programs through the arduion IDE
BLE-Nano burns the latest version of Bootloader, so you need to use the latest IDE (version 1.8.8 or
above) to burn the program :https://www.arduino.cc/en/Main/Software download latest Arduino IDE
1) "tools - \board -Arduino Nano"
Figure 2.2.1
2) click "tool-processor --" ATmega328P ";

Chapter 3 Ble-Nano and electronic device connection
3.1 Ble-Nano Connect to your android phone
1) Open the Arduino IDE, connect the serial port as shown in figure 1.9, and open the serial port
monitor as shown in figure 1.10.
Figure 3.1.1 Figure 3.1.2
2) The test AT instruction is shown in figure 1.11. The USB and bluetooth data transmission mode of
BLE-Nano is set as USB serial port data and BLE transmission as shown in figure 1.12

3) Install “Ble-Nano\TestApp\BLETestTools.apk” and open Bluetooth, Get location info
permissions
Note: Ble-Nano is bluetooth4.0 not Classic Bluetooth, So we can’t connect in phone’s setting
we need use “BLE test tools”.

on the phone(IOS install LightBlue On apple store) and open the test APP. The interface is shown in
figure 1.13. Find the corresponding bluetooth name (Ble-Nano) and click to connect. After
connection, as shown in figure 1.14, four options will appear to test different functions, respectively.
Because here we only test whether bluetooth can send and receive data normally, so we select SK
Service and select SK_KEYPRESSED as shown in figure 1.14 and 1.15
