Xinchida nd04 nd04c nrf52832 (52810) ble module (low power Bluetooth communication module) at command test

Xinchida 52832(52810) Low power Bluetooth module

ND08x ND04x Series modules are based on Nordic Semiconductor Of nRF52832 (nRF52810） Low power Bluetooth (BLE) Rf module .

The default firmware of the centrida module is to establish the communication between the module and the module , Or the communication between the module and the mobile phone

• Module to module communication

• Module and mobile phone communication
  

The functional features of the Symantec transparent firmware ：

• Multi mode switching , Lord , from ,beacon, Master slave simultaneous , Multiple master-slave devices can be connected at the same time , Each control ;
• You can modify UUID passageway , It can communicate with the master or slave devices of other Bluetooth devices ;
• The power consumption is well controlled ！ Under the same conditions, the measured power consumption is better than Nordic nrf52832/40 and Ti CC2640R2L And so on ;
• Other functions such as watchdog , Automatic reconnection , Custom broadcast , Observer mode .
• High transmission rate .

1. Environmental preparation

1.1 Hardware environment

• BT02
  

Short circuit the pins in the figure with jump caps

---

1.2. Software preparation

• QCOM Serial assistant
• BG22Ax Communication module test AT Command script (BG22Ax.ini)
• NRF nRF Connect perhaps BLE Debugging treasure

Download address ： Downloading data 　、

After downloading QCOM Import （nrf 52832.ini） Test the script as follows ：

1.3. Document preparation

• Centrida Low Power Bluetooth (BLE) Modules and protocols (nRF52810)
• Centrida Low Power Bluetooth (BLE) Modules and protocols (nRF52832)

3. use APP Test the transparent transmission function

APP You need to develop it yourself , The test phase can choose NRF nRF Connect perhaps BLE Debugging treasure

• BLE Debugging treasure （ Android phones only ）

Turn on Bluetooth and app

• Choose to RFstar_xxxx Start the Bluetooth module connection

• Open the serial port assistant to print     S:CONNECTED

 

Open the serial port to send and receive uuid

   

APP Send data to the module , Serial assistant print data

   

• adopt app Send data to the module
  
     

• Data can be received through the serial port assistant
  

Module to app Send data and vice versa

   
       

If you need Bluetooth (BLE) module
