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 stack S100 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.

Module package size 5. Reflow reference to FIG. 6. The Manual for The Serial Transparent Transmission Protocol Serial transparent transmission means that modules are connected with user MCU via a common serial interface to establish a two-way communication between user MCU and mobile devices. The module Top View Forum: bbs.wireless-tag.com WT51822-S4AT 5 / 16 Wireless-Tag Technology www.wireless-tag.com [email protected] can obtain at least 200bytes transmission data and automatically send the data by separated packets, each wireless packet maximum load is 20byte. The data packet, which is sent to the module by mobile device side, must send subcontracting automatically(1-20byte/package), the module will forward to the MCU serial receiving port after receiving the data packet. Users can modify the module basic Bluetooth parameters serial AT commands. For details, please check "serial AT command" description. 6-1、 Serial hardware protocol: default 9600bps. 8, No verify bit 1, Stop bit 6-2、 “Enable” serial ports enable control, low level enable module serial port function making data communication with the client host MCU properly; high level close s the serial port function. At this time, the module Bluetooth can still transmit broadcast code, and can be paired connection, but you can not use the serial port functions; 6-3、 In order to save the size, the module uses the TXD / RXD double wire serial methods, without increasing the data flow control. So it is not recommended to set the serial rate too high, in caseof packet loss or error code, recommend to use 9600bps or other baud rates like no higher than 38400bps; 6-4、 Bluetooth module default connection interval is 20ms, if you need to save power and adopt low-speed forwarding mode, you can adjust Bluetooth connection interval via the AT command, the longest interval Bluetooth connectivity is 2000ms; 7. Serial AT commands Description: Module will automatically recognize and distinguish serial data, the data packet began with AT charact…
