Digital Signal Dual Mode Wireless Bluetooth Sensor Module With 10m Sending Receiving Distance

Digital Signal Dual Mode Wireless Bluetooth Sensor Module With 10m Sending Receiving Distance

Introduction

The Bluetooth sensor is a master-slave Bluetooth serial port module. When the Bluetooth device is successfully paired with the Bluetooth device, the Bluetooth internal communication protocol can be ignored, and the Bluetooth will be directly used as the serial port. When a connection is established, two devices use one channel in common, that is, the same serial port, one device sends data to the channel, and the other device can receive data in the channel. Of course, there are certain conditions for establishing such a channel connection, that is, an AT mode in which Bluetooth can be paired and connected.

Technical Parameters

Product Name:Bluetooth sensor
Power requirements:+3.0V -5.5V
Signal Type:Digital signal
Interface mode:xh2.54*4
Pin definition:VCC-Power,GND-Ground,TX-Send data,RX-Receive data
Transmission distance:The effective transmission distance of the open area is 10 meters, and it is possible to be more than 10 meters, but the connection quality is not guaranteed.
Letter of agreement:After the pairing is successful, it can be used as a full-duplex serial port. No need to know any Bluetooth protocol, but only supports 8-bit data bits, 1-bit stop bits, and no parity communication format. This is also a common communication format and does not support other formats!Enter AT mode:Press the button and power on the Bluetooth module to enter the T mode, set parameters and query information.
Switch master and slave: You can switch between master and slave modes by AT command
Default baud rate: 9600
Default pairing password: 1234
Default name is: HY

Application

Arduino robot

Wiring mode

Connecting with RJ25
Since the port of Me Bluetooth Module (Dual Mode) has blue/gray ID, you need to connect the port with blue or gray ID on Makeblock Orion when using RJ25
port. Taking Makeblock Orion as example, you can connect to Port 5 as follows:

Connecting with Dupont wire
When the Dupont wire is used to connect the module to the Arduino UNO Baseboard, its RX and TX pins should be connected to digital port 0 and 1 respectively as follows:

Guide to programming

Arduino programming
If you use Arduino to write a program, the library Makeblock-Library-master should be invoked to control the Me Bluetooth Module (Dual Mode). This program serves to make the mobile communicating with Arduino IDE through Arduino programming. Whenever the data are received from the mobile, they will be displayed on the serial port. Before the communication, make sure that your device is connected to Me Bluetooth Module (Dual Mode), and send letters to it to see the running result.

Principle analysis

Bluetooth is a kind of radio technology supporting communication of short distance. Bluetooth technology can be used to effectively simplify the communication between mobile terminals, and make data transmission faster and more efficient so as to widen the way of mobile communication. Adopting the distributed network structure, Fast Frequency Hopping (SFH), and short packet technology, Bluetooth works in the global ISM (i.e. industrial, scientific, and medical) frequency band of 2.4 GHz with data rate of 1 Mbps.
