WT51822-S4AT

Bluetooth Low Energy 4.0 Module (BLE 4.0), Class 2, Onboard Antenna, AT Command

WT51822-S4AT is a high performance ,low power radio transmit and receive system module use Nordic BLE 4.1 nRF51822-QFAA as the controller chips. It has the smallest volume package in the industry, the size is 18.5*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 (compatible with BLE4.0) stack S110 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.

Features

  • Operating temperature: -25℃~75℃, typical 25℃
  • CPU: nRF51822-QFAA (ARM Cortex™-M0 32 bit processor)
  • Memory: 256KB flash + 16KB 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.
  • Serial data packet length, single data packet can support data length up to 200byte
  • Serial hardware enable control, low-power control applications
  • With the support under the test mode but not connect the serial mode, mutual communication between test module and bluetooth master devices
  • Operating distance: 0~45mclass II level
  • Support System: IOS & Android
  • Supply voltage:3.3V
  • Module comes with PCB antenna, optional external antenna
  • Size: 18.5*9.1*2.0mm
SKU: WT51822-S4AT
Brand: Wireless-Tag
