4.5 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: Not support
Q5 : Do es 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?
A6
：
In order to achieve very low power consumption, our Ble-Nano 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.
