Thanks for the detailed tutorial Saravanan, have been scratching head for a while to make this work...

Thanks for that command sequence. I used this to get my test link up and running. I'm currently testing my link by remote-echoing blocks of pseudo-random data and monitoring the STATE logic. Once the test link proves stable I'm implement my data link.

Thank you, Saravanan, finally I found video I've been looking for. And I believe out there are many people who bought BT modules at banggood and struggling to get them work or to manage to configure.Thank you for sharing your knowledge and helping us.

Thank you Mr.Saravanan for uploading this video. It helped me a lot.

thank u sir. now all my concepts regarding 'how to use bluetooth module' are clear.

Hi, is it possible to have more than one slave BT with the same master? Thanks!!!

Daaaammmnnn thats some groovy background music. Thanks for the help

Nice video, Thank you Mr. Saravanan.

can bluetooth earphone paired with bluetooth HC05 or 06 thanks for answering. i need to know if it is possible

Great work! Can you tell me how many devices can it detect at once ?

Took the mystery out of communication with two bluetooths. Thanks.

could i use another uno to connect the master rather than the usb module?

Hi i am working on bluetooth intercom is it possible to pair both device without audrino

hi. can this now be used to do what? upload sketch wireless?? we all need that one.

That was a very clear explanation! Keep it up. I just subscribed.

Hi Saravanan, Could you please guide me on how to connect HC 05 with an iPhone? is there any specific mode that I need to set for detecting this from an iPhone?

Can i use arduino nano for this project? or it just can work if i use arduino uno?

hi MR SARAVANAN thanks for the video .I followed all your instructions and my bluetooth went into config mode (slow blinking) but after opening the ide I am getting no response (JUST BLANK)from the serial monitor when i type the AT commands and i am using the same module which you are using in this video

Great music and great instructions... i had no issues. Thank you.

Hello I need help with my project, my question is can we connect bluetooth module with BASYS2 and send data via bluetooth module?

I am using Xbee pro and Xbee pro sheild to send informations from the first card uno to the seconde card uno so i can print the information on a LCD but i having a lot of problems with the configurations so do you think that is possible if i use Hc 05 ??? by a master and a slave modules ?

Hi Is it possible to have more than one BT slave with the same BT master? Thanks

Hi! Do you know why I don't have Standard Serial over Bluetooth Link COM port when I want connect to my bluetooth module? My PC pair with module, but can't see COM port? Maybe I need initialize the module with some AT commands?

Thank you. This makes sense to me now!

Hi, my HC05 can not be seen by any other devices - when i enter some of the AT commands useing Arduino programm and FTDI basic UART, some commands give me an OK but thats about it, i can not change them like slave to master, its Cmode ect.. the LED just flashes every one second and thats it. can you give me any advice?

Can these be bought pre paired? master and slave?

Thank you so much! Very helpful

sir , i paired the bt modules succesfully but the garbage is comming on slave side when i sent the data from master side i checked the baud rate of both the modules.........i m not getting what exactly the problem is. can you please suggest something.

+Saravanan AL Have you tested HC-05 with batteries or 9v battery only (which is without using power from PC) ?

Can I pair more than 2? Can I have 1 master with multiple slaves? (I'm looking for a way to have one arduino nano control -or at least talk to- 5 other arduino nanos wirelessly.)

where can i get the 7pin bluetooth module?

Why are we doing not doing cross connections for slave module ?

thanks a lot Sir..... i working hard to get into the configuration mode for some days.....you made it simple for me...... i have a question also: How many slaves can be added to a master bluetooth?

sir, can I connect a bluetooth headset with an arduino bluetooth module. is it possible?

I need to know how to connect more than one slave device to master device forming a piconet

sir where did i can by the bluetooth module HC-05 USB-TT? can u send me any link,please?

Nice video, thanks ! I've a question. I'm trying to make a call via mobile to another number when I've got some sensor value is high in Arduino's analog port. So my mobile has bluetooth chip, and I can make call with that HC05 too, but I'm confused that which registers on HC05 MUST be setup ? ROLE, CMOD? and should I make INIT after than those settings ? Can you make a video about that project too ? or can you make a list which registers MUST I setup on HC05 ? Thanks!...

thank you for posting this video, it was very insightful for a project i am working on. can you please tell me how many slaves can be connected to a master hc05?

Подскажите, пожалуйста. Можно както запаралелить два модуля блютуз?

what is the At command to change the name HC05 with user specified name???

Sir help me please while i am pair my device with bluetooth a message is displaying that can't communicate with My module...what to do?... Help please

Saravanan Ji, Can I directly pair with laptop and push my sketches? Please guide and let me know how to do that. a small tutorial will help a lot..

in my hc-05 i found those 6 pins: STATE ,RX, TX,GND,+5V ,EN.so i want to know how to connect to arduino uno?

What is the meaning of HC in the Bluetooth module HC-05?

Hello Sir, how to send serial data from one HC-05 to another? Does it automatically send data after being paired? Or do we have to use any other AT command? I am stuck with my final year project and I really need help. Thanks in advance

hi there, i paired up 2 hc05 master "1" and slave "0" doing this AT commands //SLAVE = 98d3:31:2093cb AT+ROLE=0 //MASTER= 98d3:32:204d2a AT+ROLE=1 //AT+BIND=98d3,31,2093cb //AT+BIND=98d3,32,204d2a The end im left with paired modules that can talk to one another now i set this in AT+UART=9600.0.0 or 38400,0,0 im not sure now but it worked out fine now in the sketch i was doing all this in terminal obvsly using the terminal baud rate which was as follow include SoftwareSerial.h SoftwareSerial mySerial(10, 11); RX, TX void setup { Serial.begin(38400); pinMode(9, OUTPUT); digitalWrite(9, HIGH); Serial.println("Enter AT commands:"); mySerial.begin(38400); } so my problem is that when i try to take the 2 talking modules to use in another project im not sure but they dont communicate no more "after uploading new sketch" am i suppose to use the same baud rate as in the sketch (38400); or should i be using the baud that i set this 2 up to begin with when i did the whole AT+UART=9600.0.0 or 38400,0,0 ??? i was assuming what i have now when they were talking was a wireless RS232/terminal right? if so then all i have to do is make sure in the loop of what ever other program i go to use this modules on that they talk to that SoftwareSerial mySerial or something like this void loop() { if (mySerial.available()) mySerial.write("Variable or Array here");

This is what you call: A good explaination!

Can the master communicate with more then one slave simultaneously? Can the master communicate with two or more slaves in the piconet at the same time?

how come when i enter AT+INIT it will go out to its AT command

Thank you so much sir for suppor

I am trying to set up Bluetooth communication between android device with STM 32 to control LEDs that I do not know what to do in the android device. I know the current exchange files between android phone which also controls the LEDs in STM32 I do not know. Who can help me or anything or share documents for me? Thanks!

hello sir i want to connect 8051 to bluetooth how to do it sir

sir im not able to connect my mobile with module.....in my mobile its not visible....pls fix this prblm???

can two bluetooth auto pair ?

nic video i am trying to pair my andorid phone with BT module can please give information how can i do it

sir can u help me how to pair hc-06 bluetooth modules.sir please please help mee...

Hi Saravana, I have connected my hc-05 to pins GND >> GND, VCC >> 3v, Key >> 3v, TXD >> RXD, and RXD >> TXD. Then I powered it up but I still see the LED blinking fast, which mean it is still not in the configuration mode. I am not sure how I can fix this issue, I'D appreciate your help

Can I command connect with android phone??

After all settings please dont forget to set baudrate at 9600 by help of this command AT+UART=9600,0,0, otherwise the baud rate was set as default on 38400

cant we pair two hc-06 modules

I am getting error in every command likr error,error,etc.so how to remove these errors.

sir thanks it works really,,, please tell me that how i can send files from master to slave

Very good man

Hello saravana on my HC-05 I have : STATE RXD TXD GND VCC EN i dont have "KEY" please reply thank you

i like where this video is going so far. i will update you if it works. love to my Indian people.

I cant get ok AT+INIT... why??

Very nice details ji. Dear sir I'm using all same details in HC-05 BT but BT not reply please help dear sir

PLEASE TELL ME HOW TO WRITE CODE

THE LED ON MY MODULE blinks really fast.i dont know what to do

Why is it TX->TX and RX->RX. Every other tutorial mentions the opposite.

Master module don't respond...if AT is entered it goes to next line

ANY CHANGE NEW EDITION ARDUINO UNO

thx

Sir I cant get AT +PSWD=1234

if the idea is to use the UNO's onboard USB to Serial chip as a USB to Serial UART TTL to communicate between the PC and HC-06, you can also simply pull the RESET pin to GND which will temporary disable the ATMEGA chip OR removing the ATMEGA328 chip (this will be more troublesome) without uploading a dummy sketch.

help sir plzzz

Did you record this video in a tattoo shop...?

Jesus, just flipped to the next video by accident and you damn near blew my speakers. NOT COOOOL.

Crap music but good video tips

Hi! I communicate with my HM11 module over USB to UART module, but when I connect it to my microcontroller I can't read data from it (I try to send just stream of '1'). What settings/commands should I do for bluetooth communication with my PC? Currently my PC recognized my HM11 module, but I do not see any COM port (bluetooth com port) for serial communication.
