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.

Indicator LED description
◆ 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 green light flashes when the module communicates with other bluetooth data, or when usb has data,
or when ATmega328P sends serial dataWhen the USB data cable is connected successfully, 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

Ble-Nano Connect to your 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 1.9 Figure 1.10
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_tool.apk on the phone 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

5) After clicking "send", we can see that the content sent by the mobile phone is printed on the serial
port monitor, as shown in figure 1.19, indicating that the bluetooth module can normally send data.
Of course, in order to test the accuracy more accurately, we can test it several times and try to test it
in different environments.
Figure 1.19
6) As shown in figure 1.20, we can input the content we want to Send on the serial monitor, and then
click "Send" to Send the data to the mobile APP via bluetooth, as shown in figure 1.21。
Figure 1.20
Figure 1.21
In the above test process, both PC terminal and android terminal can send and receive data normally,
indicating that the Ble-Nano communication is normal and achieves the expected effect.

FAQ
Q1: What is the difference between a Ble-Nano and a regular Nano board, and how do I start using this
development board
A1: Ble - is the Nano in the original official arduino Nano V3.0 adding CC2540 Mini bluetooth 4.0 interface
- Usb upgraded to a more general Micro - Usb interface, pin function is fully compatible with latest
Bootload Bootload burning need to use the above 1.8.8 IDE can burn, other methods of use please refer to
the official arduino Nano usage.
Q2 : Common problem of abnormal communication between bluetooth 4.0.
A2: Recommended inspection steps:
1) Update firmware to latest version;
2) Restore factory Settings by AT instruction (AT+SETTING=DEFAULT). (see: configure BLE
devices by AT instruction)
3) Check whether the communication baud rate of bluetooth module, program code and other relevant
places is consistent; (the control panel with a crystal oscillator frequency of 8MHz supports a baud
rate of up to 38400bps.)
4) Whether the bluetooth device supports 4.0 or not, there will be compatibility problems with the
bluetooth module of CC2540 and other brands. Please try your best to connect with the bluetooth
module of CC25xx
Q3 :Why can't my phone connect to the Ble-Nano, and even if it does, it can't communicate?
A3: Please check whether your mobile phone supports bluetooth 4.0. In addition, please use the Scan button
in the APP to Scan the connection of Ble-Nano. No password is required for connection. The bluetooth
setting interface and other BLE apps are not supported.
Q4:How to use Ibeacon function?
A4: You can find relevant instructions to turn on/off the Ibeacon function in the AT list, and then download
an Ibeacon query software in the app market, and you can query Ibeacon. AT this time, Bluno is an Ibeacon
label.
Q5 : Does Ble-Nano support multi - connection? I want to connect many slave machines with one host, how
many can I connect at most?
A5: Ble-Nano does not support multi-connection, but the idea of multi-connection can be realized by
constantly switching binding slave machines.
Q6 : Why can't the Ble-Nano bluetooth 4.0 products connect to bluetooth 2.0 devices?
Copy right © 2018 Shenzhen Emakefun Technology co., Ltd.
26
A6：In order to achieve very low power consumption, our Bluno series adopts single-mode Bluetooth
Smart, which is optimized in both hardware and software, and can only support BLE, but not connected to
Bluetooth 2.0 devices.
