At 8:14 , we should connect back "TX-TX" and "RX-RX" while sending the AT commands to the HC-06 module. Note : We should always send an empty code (the default code of a new project) to the Arduino before sending the AT commands to the HC-06 module. While uploading any code to the Arduino, we should always disconnect TX & RX pin of HC-06 from the Arduino board. Point to be noted : * For sending AT commands, Connect--------"TX-TX" & "RX-RX" * During working of the circuit, Connect--------"TX-RX" &. "RX-TX" * During uploading the code, Disconnect----------"TX" & "RX"
NOTES ON VIDEO BELOW NOTE 1: THIS VIDEO IS NOT FOR THE HC-05. This is for the HC-06. They are significantly different. NOTE 2: There are a couple of spots in the video where I'm clearly befuddled with why they silkscreen arduino ports, TX > [pin1] = receive and RX < [pin0] = transmit. I personally believe the receive pin should be labeled RX and the transmit pin should be labeled TX. But apparently that's crazy talk. :-) NOTE 3: At 8:14 make sure to plug Bluetooth back into ports 0 & 1 NOTE 4: Make sure Receive and Transmit are cabled up correctly after you upload blank Sketch. The silk screen on some Arduino devices can be confusing, being the pin that RECEIVES is actually labeled TX with arrow pointing IN and the pin that TRANSMITS is labeled RX with arrow pointing OUT. (See graphic here. Notice the two modes if you will th-cam.com/video/is3EaCSnJyo/w-d-xo.html) NOTE 5: Make sure you are dropping the TRANSMIT voltage from the Arduino to 3.3V using the VOLTAGE DIVIDER (th-cam.com/video/is3EaCSnJyo/w-d-xo.html) NOTE 6: In Arduino serial monitor make sure you have the correct speed and line settings ( th-cam.com/video/is3EaCSnJyo/w-d-xo.html )
When opening the COM serial monitor after uploading the empty sketch via USB cable, i type "AT" and the port does not return "OK". Got any thoughts on why it might not be working? Thanks
@@tophertmg Hello I am running your script and I cant seem to have it display via bluetooth on the putty window , if i type anything in the serial monitor top bar it shows up on the putty window but the heartbeat Arduino says hi will not show up. appreciate some advice thanks
What if we connect directly the 3.3V pin of Arduino board to the HC-06 module , instead of connecting the voltage-divider to get the desired 3.3V ? Will it work ?
Yeah the HC-05 is a bit of a different animal. Other than being and acting a little different, I think the hardest thing is to make the voltage divider (in video at 2:40). Best of luck.

In the beginning showing on a piece of paper how voltage divider is applied for RX is great.Amazing job!
Thanks. I run on positive feedback.

Thank you for this tip. I needed it!
Thank you for this tutorial!
The arduino uno has 3.3V available at its one of of the port, so why not use that. Thanks

i was wondering why the hell there were a lot of changing lights and stuff and no messages at the com of arduino IDE, thank you so much sir
great job! I found answers to mt questions! Thank you!

This video is awesome, you're awesome. Thank you so much!!
Awww shucks. Thanks for taking the time to say so. There are a couple of wonky bits in the video but hopefully it will get you over any major hurdles.
You hit the mark on this training, good job.
Thanks! I always appreciate a person taking the time to say so.
Thank you, this was very instructive :)
why adding extra 2 resistor was necessary in newer hc-06 than the older version hc05 which has no resistance to be included in circuit.
When opening the COM serial monitor after uploading the empty sketch via USB cable, i type "AT" and the port does not return "OK".
Got any thoughts on why it might not be working?
Thanks
Im having the same problem , please if you solved it could you tell me how
@@nuraqasrawi6014 haven’t figured it out, nobody in my class has. I’ve pretty much given up on uploading via Bluetooth
same problem. been pulling my hair for a while
I have the same problem. The module does not respond to AT commands.

Excellent work, sadly not for me. The thing is I tried a lot to get into AT mode but no luck so far, and I'm out of videos in YT now xD
same here man
same
Can you please add the code you used at the end of the video?

It's touch and go. Sometimes it works for a little bit, but in my experience, it was very unstable, if it worked at all.
Lire les données d’un appareil Bluetooth et transférez-les vers le cloud, et vice versa. ??
Thankyou, worked as you stated, wish I could get the HC-05 to work. I think the board has a fault. It works but won't respond to me. Thankyou again

sir I am using plc2303 but not getting any response for AT commands
I have HC-05 without push button... How I can do?
SVP, comment faire une liaison entre le cloud et une Arduino UNO par Bluetooth
Ce serait une autre vidéo utilisant des techniques totalement différentes, mon ami.
