How to interface Bluetooth with microcontroller?
To enable Bluetooth communication the Bluetooth module is used widely. This module is interfaced with the 8051 microcontrollers by using the UART and the data is transmitted in the form of packets. The path for the data transmission and reception is formed by using the pins of Tx and Rx of HC 05 Bluetooth module.
What is the meaning of HC 05?
Introduction. HC-05 Bluetooth Module is an easy to use Bluetooth SPP (Serial Port Protocol) module, designed for transparent wireless serial connection setup. Its communication is via serial communication which makes an easy way to interface with controller or PC.
What is difference between HC 05 and HM 10?
Difference between HM10 and other Bluetooth Module The major difference HM10 possess is the Bluetooth Version. The HM10 is Bluetooth 4.0 module, so it comes with all Bluetooth Version 4.0 features such as speed, throughput and range. The HM10 offers a data rate of up to 24 Mbps with low-energy/low-power consumption.
How do you use the Bluetooth App on the terminal?
First you must turn on the Bluetooth on your Android phone. Search the bluetooth device and pair with it (the password is 1234). Then open “Terminal Multi” and press the button “SEARCH” for select the paired device (HC-05). In the end press “CONNECT”.
What is the use of HC 05 Bluetooth module?
Designed to replace cable connections HC-05 uses serial communication to communicate with the electronics. Usually, it is used to connect small devices like mobile phones using a short-range wireless connection to exchange files. It uses the 2.45GHz frequency band.
What are the features of HC-05?
HC-05 Specification:
- Bluetooth protocal: Bluetooth Specification v2.
- Frequency: 2.4GHz ISM band.
- Modulation: GFSK(Gaussian Frequency Shift Keying)
- Emission power: ≤4dBm, Class 2.
- Sensitivity: ≤-84dBm at 0.1% BER.
- Speed: Asynchronous: 2.1Mbps(Max) / 160 kbps, Synchronous: 1Mbps/1Mbps.
- Security: Authentication and encryption.
What is the difference between HC 05 and HC-06?
The HC-05 can be a master or slave. The HC-06 is a slave only. This means the HC-05 can initiate a connection to another device and the HC-06 can only accept a connection from another device.
How do I test bluetooth HC-05?
Testing HC-05 bluetooth module using Arduino UNO as serial to USB converter
- First make sure your HC-05 Bluetooth Module is paired with your mobile.
- Click on “SELECT DEVICE” icon to select paired Bluetooth module.
- When you press “UP Arrow” it sends the data “A” to Bluetooth Module connected with the circuit.
How to interface Bluetooth module HC 05 with PIC microcontroller?
Bluetooth module HC 05 interfacing with pic microcontroller: Hi Everyone, In this article I will explain you how to interface Bluetooth module HC 05 with pic16f877a microcontroller or any other microcontroller like 8051, AVR and Arduino. It is very easy to communicate with android mobile through Hc 05 Bluetooth module.
What’s the voltage of the hc-05 microcontroller?
The HC-05 sub-module works at a 3.3v logic level. And the breakout board that we’re using has an onboard voltage regulator, that’s why we can supply it with a 3.6 to 6v. However, the UART logic isn’t at the 5v level as you might have thought, it’s 3.3v in fact.
Can a hc-05 microcontroller be used as a slave?
However, it’s fairly easy to set up and interface to any microcomputer system over the serial UART. HC-05 can be set to be either a Master or a Slave. These small modules run on 3.3V power with 3.3V serial signal levels, They have no pins and is usually soldered to a larger breakout board.
What kind of serial communication does the hc-05 have?
The module normally operates at UART serial communication with TX and RX pins at 9600 baud rates. It offers a two-way communication method and the HC-05 can act as either slave and master.
