SPP-C Bluetooth serial pass-through module wireless serial communication from machine Wireless SPPC for arduino Bluetooth Module

SPP-C Bluetooth module

Technical Manual

Outline:

           SPP-C Bluetooth module is designed for intelligent wireless data transmission and create follow V2.1 + EDR Bluetooth specification.

     The module supports UART interface, and supports Bluetooth SPP serial protocol, low cost, small size, low power consumption, send and receive sensitivity advantages, with only a few external components will be able to achieve its powerful features.

 Features:

Bluetooth V2.1 + EDR

Bluetooth Class 2

Built-in PCB antenna RF

Support UART interface

3.3V power supply

Application:

This module is mainly used for wireless transmission of data in the field a short distance. And PC can be easily connected Bluetooth device, it can also exchange data between the two modules. Avoid cumbersome cable connections, can directly replace the serial cable.

Status Indicator LED: P12

Bluetooth module which is used to indicate status, LED light flashes and a Bluetooth module corresponding to the state as follows:

Host interrupt instruction: P05

Host interrupt for indicating whether or not the connection state is high, the other low-level state.

LAYOUT Notes

1 SPP-C serial port Bluetooth module level required to 3.3V, and 5V level if connected to the system need to increase the level switch chip.

2 Bluetooth signals by the surrounding great influence, such as trees, metal, walls and other obstacles will have a Bluetooth signal absorption or shielding, it is recommended not to install metal being.

3 Since the metal will weaken the antenna function, it is recommended to Lay board module, the module antenna shop and do not go below the line, the best knockout.

SPP-C Bluetooth serial communication module

AT command set

Users can be through the serial port and SPP-C chip communication, serial port Tx, Rx two signal lines, baud rate support 1200,2400,4800,9600,14400,19200,38400,57600,115200,230400,460800 and 921600bps. The default serial port baud rate of 9600bps.

Instruction Set Description

SPP-C Bluetooth serial module instruction Command instruction set.

   (Note: You must carriage return when the AT command, AT commands can only take effect in the module is not connected, the Bluetooth module once the device is connected, the Bluetooth module enters data transparent mode \ r \ n to press the computer. Enter key, if not press the Enter key to add \ r \ n.AT command case insensitive)

1   Test command:

2 Module reset (restart):

For example:

AT+VERSION\r\n

+VERSION=2.0-20100601

OK

Example: Send AT + LADDR11: 22: 33: 44: 55: 66 \ r \ n

Returns + LADDR = 11: 22: 33: 44: 55: 66

Then the Bluetooth address code read 11:22: 33: 44: 55: 66, the module default address code is AA: BB: CC: 11: 22: 33.

Example: Send AT + NAMEBOLUTEK \ r \ n

Returns + NAME = BOLUTEK

Then the Bluetooth name changed BOLUTEK

Parameter support power-down save.

Example: Send AT + PIN8888 \ r \ n

Returns + PIN = 8888

Then the Bluetooth pairing password to 8888, the module default passcode is 1234.

Example: Send: AT + BAUD6

Returns: + BAUD = 6

At this baud rate to 38400

Note: After baud rate change, if not the default of 9600, when after the parameter settings or data communication, use baud rate settings.
