WT51822-S4AT Ultra Low power beacon based nRF51822 bluetooth module 4.2 with CE/FCC

Product Description

WT*****-S4AT BLE module profile: 

WT*****-S4AT  is a high performance ,low power radio transmit and receive system module use Nordic BLE 4.0

nRF****2 as the controller chips. It has the smallest volume package in the industry, the size is *8.5*9.1*2.0,

suitable for most applications which pay more attention to the size. The module integrate the complete standard low

energy Bluetooth 4.0 protocol stack S**0 drive. Customer's MCU is connected to the module by UART

port, it will automatically send a broadcast code after the module starts. As the master, APP device can scan and

search the broadcast from module in order to establish the connection. After success, it can conduct two-way

communication link with mobile device APP by serial port. Through UART interface, the user can exchange data or

control the communication parameters of module. The meaning of data is defined by the upper application

user. The mobile device can operate to the module through APP, the data will receive by the module and

pushed through UART MCU. After the module received a data packet from the client MCU serial port, it will

be automatically forwarded to the mobile device.

 

WT*****-S4AT BLE module features:

• CPU: nRF*****-QFAA (ARM Cortexâ„¢-M0 *2 bit processor)
• Memory: **6KB flash + *6KB RAM memory
• Transparent transmission (Bridged method) easy to use and fast, no Bluetooth protocol stack
• development experience can use too.
• The user interface uses a standard UART (TTL) Interface, bidirectional data read, easy to operate.
• Supports serial AT commands, the user can modify the basic parameters like the serial port baud rate,
• name, MAC address of the module, etc.
