Arduino Bluetooth HC 06 + AT Command Set: A Comprehensive Guide: 4th Edition 

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"

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

You hit the mark on this training, good job.

Thank you, this was very instructive :)

great job! I found answers to mt questions! Thank you! +1 Subscriber

This video is awesome, you're awesome. Thank you so much!!

sir I am using plc2303 but not getting any response for AT commands

Can you please add the code you used at the end of the video?

I have HC-05 without push button... How I can do?

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 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-is3EaCSnJyo.html) NOTE 5: Make sure you are dropping the TRANSMIT voltage from the Arduino to 3.3V using the VOLTAGE DIVIDER (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-is3EaCSnJyo.html) NOTE 6: In Arduino serial monitor make sure you have the correct speed and line settings ( ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-is3EaCSnJyo.html )

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 ?

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

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

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
