Product Description
- The BLE Board has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers.
- The ATmega328P provide UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX).
- An TI CC2540 chip on the board channels this serial communication over USB and the TI CC2540 chip drivers (included with the Arduino software) provide a virtual com port to software on the computer.
- The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board.
- The RX and TX LEDs on the board will flash when data is being transmitted via the TI CC2540 chip and USB connection to the computer (but not for serial communication on pins 0 and 1).
- A SoftwareSerial library allows for serial communication on any of the Nano's digital pins. The ATmega328P also support I2C (TWI) and SPI communication.
- You can download all materials from https://github.com/emakefun/emakefun-Ble-uno

FAQ
Q1: Why can't my mobile phone connect to Ble-Nano, even if I can connect, but can't communicate?
A1: Please check if your phone supports Bluetooth 4.0. In addition, please use the Scan button in the APP to scan and connect to Ble-Nano, and the connection does not require a password. Mobile phone Bluetooth settings interface and other BLE APP connections are not supported.
Q2: How do I use the Ibeacon function?
A2: You can find the relevant command to open/close the Ibeacon function in the AT list, and then download an Ibeacon query software in the application market, you can query Ibeacon. At this time, Bluno is an Ibeacon label.
Q3: Does Ble-Nano support multiple connections? I want to connect a lot of slaves with one host. How many can I connect?
A3: Ble-Nano does not support multiple connections, but it can achieve the idea of multiple connections by constantly switching the binding slaves.
Q4: Why can't the Bluetooth 4.0 products of the Ble-Nano series connect to Bluetooth 2.0 devices?
A4: Because our Bluno series uses a single-mode Bluetooth low-power (Bluetooth Smart) to achieve very low power consumption, hardware and software are optimized to support only BLE, and Bluetooth 3 devices are not supported.
