Such a deceptive video. I searched for something completely different and UKposts throws this up this garbage as the first result.

Thanks very much for this! Your explanation was very useful. Thanks for telling us about chars too.

Kept getting an error, that there was no programmer. It must be a change in the IDE from this version. In the end, when uploading to the AtTiny via the programmer, do not use the usual "Verify and Upload" buttons, but enter Top menu- "Sketch", and then use "Upload Using Programmer". Worked like a charm after this! Thanks!

Music not good

Hi, I want to send an int type array of lenght 34 over BLE and recieve it using matlab. can you please help me out here how to proceed!

Invalid head of packet (0x00) error . Help

Great video and everything was explained very well.

I did it and it looks awesome I can't wait to show it to my friends Perfect tutorial bro!

Hi , I would like to replace HM10 by the ESP32 BLE so that the existing Android and IOS app's can be used without the need of the HM10. Can you or someone here give some advice please? I changed the UUID's already but that seems not enough. How to modify the code to replace the HM10? Thx.

What app are you using on your Android phone to see the BLE device with characteristics and values being sent?

merhaba yükleme yaparken "Upload error: A programmer is required to upload" hatası veriyor. Sebebi ne olabilir?

I can clearly say this is the best useful video for the beginners. Thank you. Could you please make a demo video for internet connection between arduino board connected to the ESP8266 board as well?

Love from Kerala thanks bro ❤️🔥

Good job, thanks a lot! ✌🏼🇧🇷

Good job! Thanks..

My pc don't have molex wire 😭

bruh too much object

im having an extremely hard time making this work on a psoc 6 board, the code is kinda similar but some of the concepts differ a little bit, if possible, could you do a tutorial with a board of the psoc 6 family using Eclipse IDE?

Super helpful to have this info in a short video I've been able to rewatch whenever i need to write BLE code. Thanks!

Thank You I am late to the party but trying to catch up great video, Dennis

That was very impressive. I'm an engineer and I always do things like that. Once a person with engineering talent who has some experience with systems, then ideas just pop into the mind. So trying to accomplish what has been imagined is so compelling. "Why not, lets do it!" Thanks, such a true video, and you made a great system. You ought to sell them, or at least post the schematics, code, and component list. Thanks again, that was cool!

Oh boy... Finally, an Indian boy comes to rescue the BLE developer. Thanks.

I am trying a led project as a beginner with this board. How you set up an app in the tablet to do this. Where i can find a tutorial?>

Can you program the ATTiny24/44/84 in that larger socket?

Slow down and turn off music please.

Those lights look super awesome in the computer case! You did a great job.

how to configure wifi by using ble in esp32 using arduino? Do you have any video in this regard?

Bro can we send data that readed in arduino using sensor at time WiFi module connected

my corsair molex has all black wires... what to do??

Every thing is fine and insyructable,instructive, question is contents of video is important,or background music is. If music is important then put only music. Thanks

Do you do freelance works?

Nice one

You seriously need to speak clearly you uneducated third world class simpleton.

Hi there. I hope you are still active. I need to build a bluetooth scanner which fires a relay when a specific bluetooth device is in the proximity. I have a firebeetle and the arduino IDE. I am lost from that point on. I can't find the board in the list, I cannot seem to connect. Yes, I am a n00b

Why does your esp8266 have a capacitor attached to it

Amazing content bro.

Good day sir, why is that in arduino I experience error when connecting Tx to Rx and Rx to Tx? Thank you for the answer

Interesting thank you

Why the music????? Terrible!

Good tutorial, thanks.

Thank you so much, for the through explanation of the BLE basics, even though I knew most of it, you clarified some of questions I had.

Capictor use karo

Thank you so much This is helpful

What should I put in the ESP32 disconnect function in order to let the ESP32 be advertised for a new connection? Its seems the code in the setup is executed one time and when I disconnect client device (a MIT appinventor custom app) I cannot reconnect again. The ESP32 server is stopped - maybe you have a link to correct configuration for a MIT app disconnect command?

attiny board manager cont instol

Thank you so much!!!!!

Nice and clear - shame about the stupid music

How can I send json data via bluetooth?
