I have HC05 and I tried almost everything but I see serial monitor shows "ready" but entering AT does not return anything. Please help!!

[@prestononuselogu9973]

I have the same issue

[@MynameisBarry]

I've tried many tutorials, every try wasn't success until i watch yours ! Thank you !

[@DIYGUYChris]

Keep on going forward 🤟

[@xpymka9832]

THANK YOU, BRO! My stupid teacher gave me a code that didn't work with this module and insisted that everything was correct, and it turns out it was me being foolish. I searched the entire internet because of him to find out how to connect it properly and make it work, and then I accidentally stumbled upon this video. I tried doing everything as you showed, AND IT WORKED! Thank you so much for the video XD.

[@DIYGUYChris]

Keep up the good work 😉

[@HarryColvin-o3t]

Just a quick question. Are all kcx bt emitters the same as far as AT commands?

[@arletpaz8010]

i tried this on a nano and a uno and nothing.........this dont work at all!

[@karanbhardwaj3599]

Thank you so much for this video. I am new in IOT and I just started making things. I made serial communication between laptop arduino over bluetooth and I will work on NodeMCU. This is most interesting thing and I believe software , hardware and your creativity can make world changing technology .

I just found out about your channel and I subscribers immediately because almost every question I had got solved thankyou

[@sarette509]

Thank you so much MEGA DAS u were of great help with my electronics engineering final year project😊😊😊

[@muhammedimdaad]

why did u assign 38400 at the beginning and then changed it to 9600???

[@DIYGUYChris]

That's the default baudrate and it could be set as whatever BPS you need

[@shubhammarathe534]

Hey. I want to use arduino uno, mpu6050 and hc 95 Bluetooth module. The problem is about power supply. Can i power hc 05 bt module or mpu6050 with external battery? If yes then please tell how

[@DIYGUYChris]

Hello yes you can use external power supply, just use an external 5V DC power adaptor and connect its (+) wire to Bluetooth VCC and (-) wire to both Bluetooth and Arduino GND then from Bluetooth to Arduino just Tx to Rx and Rx to Tx
Same for any other device

[@shubhammarathe534]

@@DIYGUYChris Thanks buddy. Can i share my fritezing digram for my project with you? To clear doubts about it. Actually i am doing Arduino project first time so for doubts can i?

[@user-jl1qb6qg4t]

Why does my bluetooth HC-05 have a blue LED blinking

[@chrisking3639]

You show the HC06 but then don't show how to connect it or (the issue I am having) getting it into AT mode as it doesn't have a button. Any other vids or suggestions?

[@davechapman5572]

Thank you for the video. It worked fine the first time I tried this, but the second time with the same HC-05 it doesn't work. It won't send back anything after sending "AT". What did I do?

[@livinginOrwells1984]

Same here, except doesn't recognize but shows some gibberish in serial monitor and won't show up in scan on bt terminal app

[@chuicoevenmerk]

Can I make the Bluetooth. Or configure it as Bluetooth speaker only?

[@bencypg]

Not able to set AT+POLAR,1,0 using USB to serial convertor. All other command works fine. Tried 3 different HC05 and also different USB to serial convertor but only this command does not work. Please help

[@dlofton123]

The current name of my buetooth HC-05 does not show up when scanning on my windows PC

[@shahnewajbd4623]

After that how can i communicate with mobile phone Bluetooth,, please help me

[@ioanesichinava6668]

Hello, I have next problem. I changed Name, But when I Change PSWD it save on serial monitor and not connect Mobile, it is write " incorrect Pin or PassKey" why?
thanks

[@pepopepez105]

not response AT ¿?

[@michellejacob2566]

Hey, I have a doubt. As soon as we connect it with Arduino and enable it, we will get to see its name in the bluetooth option on phones?

[@DIYGUYChris]

You will see the name on phone Bluetooth search as soon as you power the module, with or without connecting it to Arduino, as soon as you wire the VCC and GND pins.

[@nkostelidis]

Hello. Is it possible to change data bits from 8 to 7 with AT commands?

[@kobitadurgesh6123]

This very useful video elctronic lovers and i also love this video

[@maddilasumanth7888]

When I type AT then I am not getting ok or ready.
White blank screen only visible.
Please slove this problem

[@DIYGUYChris]

Hello
Are you setting the appropriate baudrate?

[@bananakids_1212]

⁠@@DIYGUYChrisSame issue, yes the correct baudrate was set

[@JohnBacas]

Nice video..!! Keep up the good work. I would expect a little more explanation about the AT commands, not just "read the link in the description"...

[@miaharley8051]

Awesome
Keep going
I suggest to make videos about some sensors the way you did with the motors, that was useful

[@ariviyalarivom6507]

can we do this using arduino uno? or does it requires a controller with two rxd and txd pins?

[@DIYGUYChris]

You can do it with Uno because of the simple reason that the Uno microcontroller is similar to Nano microcontroller, follow the same wiring as mine and use the same code

[@livinginOrwells1984]

Hi Chris, can you tell me if I can use the 'D0' and 'D01' pin that are labeled 'tx' and 'rx' instead of the D2 and D3 pins you show? Please help! :)

[@DIYGUYChris]

Hi
The Rx and Tx pins of Arduino are occupied by the Serial monitor but you can wire the Bluetooth to those pins after completing the Bluetooth AT command configuration.
Let me know if this is not clear enough for you

[@livinginOrwells1984]

@@DIYGUYChris Okay thanks Chris, really appreciate it! I finally got it AT commands working and connected again and will try those tx and rx pins and lyk. Cheers!

[@livinginOrwells1984]

@@DIYGUYChris Forgot to ask...what do I have to type in code to upload after switching to tx and rx pins? 'D0' and D1' or some form of tx and rx?

[@chalanisiriwardhana8426]

This tutorial is very good but I couldn't change baud rate. Can you give some advise for that please?

[@DIYGUYChris]

Have you tried the appropriate AT command line for baud rate changing?

[@puntergaming2455]

Sir I have a question that can't we use a remote which can connect to the bluetooth module and cantrol what ever we want but why we only use our phone so plz can show us how can we do it???
Love from India ❤️❤️

[@timm3802]

AT command to change pin, need to be in " " - else it will not work. AT+PSWD="2022" will work.

How about at command for Esp32? Can u do that?

[@marsanishadraa]

this is a great video, thank you, but why when I open serial monitor the reply that I got is nothing? not OK like in your video

[@DIYGUYChris]

Probably you are not setting the serial monitor baud rate as same as the one you set for your Arduino Serial! Check it and check the wiring diagram as well.

[@sarthakmishra5418]

Sir I am a beginner and having a lot of interest in Electronics. I study in class.7 and learning programming c++ and python since class.3

What is full form of HC in HC06

[@Amine-dlmr]

Why i dont see anything on my serial monitor?

[@Amine-dlmr]

ive tried all the baud rates and double checked my connections. My HC-05 is in AT-MODE and nothing appears. Even when i try easy ON/OFF code with an android device, nothing show up. What can i do about it?
