Amazing!! Thank you for all the hard work you put into making these videos, I appreciate Part 1, 2 and 3. Very clear, concise, and very useful to all of us! Everyone should be using these videos to learn the basics and create awesome projects using the ESP32!

u've no idea how much u helped me .. at least cutting few months in my studying to 1 h of your videos ! .. be blessed

Thank you very much for sharing this tutorial. I have struggled with some old examples with Bluetooth and Android Studio without success. Your example is much more easier than Java.

Thank You for helping GreatScott! with his latest video!

Wow thank you very much , you are a super educator. I want an app to control the speed and direction of my outdoor battery operated Locos, now i have to learn app inventor , should be a piece of cake. I will try your other videos first. Thank you again Mo

Thanks a lot. You have described every things very clearly. Highly appreciated.

Wow! Thank you for posting this here. Worked so well after your great instructions and files. I used the onboard RGB led that was on my ESP32.

Excellent video. Keep it up. I'd love to see more App Development with MIT App Inventor and ESP32. Thanks a lot.

Thank you very much, now i can open my Garage again via Bluetooth. My old Remote was faulty. At 12:10. Hm, i think, enter the the 6 Digit Code ist much esier.

Very professionel working through, Please keep posting. Thank you

Duuuude!!! This is the content that we want!!

Thank you so much for this tutorial! I look forward to viewing more of your content :D

Thank you for the clear and helpful content! Keep it up!

Good video, new subscriber here. I might suggest for the 1/2 of the world that uses the iPhone, an "Not for IOS warning" could be helpful. Good video though, informative and direct while still being simple in nature.

this sounds so exciting... just found out about RemoteXY then came across this... let the show go begin... 😊 thanks. esp32 with onboard oled and bluetooth android-phone

very informative, thank you so much

Thanks for the clear video. One comment: The graphic interface of MIT inv. is not the best practice: hard to maintain, comment & debug. It may be easy to start with, but there is a long term penalty.

fantastic project.

That was really helpful thank you so much♥

Very good tutorial which has cleared up several things that weren't clear to me. One question though - is it possible to get the Esp32 to communicate with another ess8266 or esp32 via Bluetooth or Espnow_ while the esp32 is connected to the phone by bluetooth? I would like to be able to send several bytes to a secondary esp device based on sensor input that was evaluated on the primary esp32. That data is to be sent only - nothing is received back from the secondary esp.

Thanks a lot for your detailed and understandable videos! All parts were very helpful for me to step into the BLE topic, which I never used before. The example works perfect on my mobile and on ESP32 and I only spent some hours on it. I want to control my garage door with it. Please give me a hint, how I can modify the example, that the app connects automatically with ESP32. I also would likt to have a push button function, that same message is sent to ESP32, when the button is pressed. Only when pressing, the outlook shoud change and afterwards the button shall return to default state and default outlook. thnaks for your feedback.

Super video, thank you! Great explained! Could you please make a video to do wifi straight phone to esp? I need a longer control range. Thx

Any thoughts what would be involved in writing an ESP32 application, that takes data from the uart, and passes it wirelessly either via bluetooth** (SPP) or via Wifi? One way communication is fine for now (RS232->ESP32->BT/Wifi - - - - > Mobile/PC) For Wifi, I imagine the ESP32 could act as a web server (TCP) and display the RS232 data, but maybe there's also a UDP way of sending the data to a PC on the same network? If the receiving application (mobile or PC) is written with the flutter framework, it could display the RS232 data with style! **I purchase some USB-bluetooth dongles (Feasycom BP102, HC-05/HC-06/CP2102 master modules, etc).. but none can connect to any android phone! For example, when a Samsung S5 tries to connect to one of the bluetooth dongles, it will stop blinking, but after a couple seconds, Android says 'Can't communicate with the FSC_BP102' or HC-05, or HC06, etc.

Hello, thank you for the content, only question I had is if the whole process can be applied for the ESP32 that uses WiFi instead of bluetooth?

Sorry, I changed the board to ESP32-WROOM-DA module and it now compiles.

Great Tutorial! I just want to figure out, wther to use the BT-Client or the Server for my similar project. Now I got a good insight into this theme. I also like the Room: It looks like my studio, Ive got exactly the same Strat Sunburst hanging on the Wall \O/ TNX.

Hello mo_thunderz, thank you very much for the tutorial but I have followed all your steps and I cannot connect with the esp32, it is synchronized because the esp32_Control of the android mobile disappears from the screen but it does not mark the status and nothing is seen through the serial port of arduino ide, if you could help me thank you very much for your time.

This is very helpful. Thanks. Do you have anything that covers proximity detection to the ESP32? For example, if the phone were closer or further away from the ESP32 then the phone would display some kind of output to inform me.

..very good tuto..Thanks!!!👏

Hi. Great video. Thanks for sharing it. Do you know if it is possible to share the .apk file with another user without them having to use the MIT Inventor program?

Can you make a tutorial on this for Android studio?

Can u plz explain why 516>=error number, why it is 516, what is happening when is lower or higer than 516. Thank you.

Do you have a video where the Bluetooth app will save the data to the esp32 that is persist after reboot of the esp32?

You are one of the best!

Very professional presentation, thank you. I too got stuck with Bluetooth and the iPhone. I have a button input and want to pass a signal to my iPhone to creat a tone. I can create the tone on the Esp32 and play it on a speaker but I can’t figure out how to pass it to the iPhone. I can use the WiFi in the Esp32 but don’t know how to pass the digital code and then play it on the iPhone. Can you please give me some direction or help? Thanks Dr. J

Excellente présentation...Merci beaucoup

Hi , i am creating a device that has esp32 and the other device is Pi5 which runs android os an app can be installed in this os . Now , i need to connect my esp32 with the pi5 only . Can you guide how i could do this ? In my mind .. it is giving characterstic id call from esp32 and the app would have the same the characterstic app . If the app detects the characterstic app , then connect directly to esp32 . Please let me know if this is right or show avideo on how to do this as a refernce

Hey Mo! Thanks for the great tutorial. It works perfectly on my Google Pixel but the problem is that the device does not show up on my iPhone, even with Bluetooth LE apps. Do you have any idea how to fix this?

Thank you so much Mi o ni WA e ti

Thanks a lot for this tutorial! I searched for a solution to connect my lora-wan lilygo t-beam with my android phone with btle to send gps data right to the phone. I will write an app to open the coordinates with an offline map to show the location of the gps-enabled lora-wan sending device off-grid.

very useful video thank you

Great video. I am having compile errors. I am using ESP32-S3. Will this work with this version ESP32?

very good. thank you so much

Hello1 Thanks for a really great tutorial. im currently working on a project that needs more than 10 buttons for on and off swiches, how is that done in the code? Best regards Emil

Pin( 1234/abcd ect) Authentication while pairing is possible ?

i have it uploaded to my esp32 and it showed like yours with the last line Hard resetting via RTS pin... but i do not see in in my bluetooth devices

can you please tell me which pin you used for the first button? Looking forward for your response. Thank you so much.

I cant get it to work when i remove connection to the Computer and run only external powersupply, WHY??

With this, I could connect a webshop on the internet to a anduiro that controls my.vending machine at home? So people can buy online and pickup?

wow thank you so much i have only just found you on the net, you really know your stuff. I on the other hand am not as clever as you with this sort of thing. I am trying to understand a project i would like to make, to be honest i am not getting too far, i brought an esp32 Arduino board and a PN532 NFC board. What i was thinking but i don't know if it will work is for me to scan an nfc chip on the pn532 and the esp will collect the address and notify me on my android phone. after reading so much i think it is possible. are you able to give me any advice or direct me to a video that will give me all the info i need to be able to do this please.

thanks for a video , is there tutorial with .ino file for wifi method ?

Hi, amazing tutorial, can u make app to connect using Bluetooth low energy, please please please

i can't find bluetooth with iphone SE3 , i necressy to used Android ?

very good video Thanks

Great video. I'm trying to make an app with MIT inventor for a dc motor controller that has forward, reverse buttons with a speed slider control bar. I am using an esp32 and L298N but not being very successful. If you can do this then I would be grateful if you can post an ESP32 sketch with MIT design app and blocks. ? Rob

ive got this ereur help please no matching function for call to 'BluetoothSerial::BluetoothSerial()'

HI. I'm having problems with the BluetoothSerial. Code is compiled properly and send to esp, but I cannot find bluetooth device on my phone :( I tried many different coded for that (examples incl.) and no luck. I'm using newest IDE 2.0.1 but i got the same problem on older 1.8.x. I tried two different ESP. SimpleBLE advertises device properly.

BluetoothSerial ESP_BT; on line 9 of the arduino sketch gives this error when compiling: "'BluetoothSerial ESP_BT' does not name a type "

Does this mobile App works also without Internet connection after testing and developing ?

what happen if we want to use this following code for more than 15 button?

Sir if clicked push button on arduino I want a text message in mit app, how can do it? Sir plz help

is it possible to control esp32 via USB-TTL converter sending data to it from an app created with MIT app inventor?

nc work

Does this work the same way with an iphone or are the more steps that need to be taken

Hii I have problem with "BluetoothSerial.h" it give me error Verifying ... Can someone help me to understand what i do wrong? Thanks for the awsome video

Can u make clock built in to esp32 & make timer by clock like blynk to turn on/off automatic by set time in mit app ? Im try but never succes. Hope u can help with video 🙏 Thx.. from ur's new subscriber

Hi, thanks for the great video. It is working perfectly on AI companion but when I try to build the .apk and install the .apk on my android phone, it is not working on the part Connect To Bluetooth. The list of BluetoothClient are not showing up. Do you have any idea what is causing this matter since it is working perfectly fine on AI companion?

great!

hey mr is it possible to connect the mit app with bluetooth in real time?

nice job

How i can receive value from android studio app Instead of mit app ?

Can anyone help me? I created an app via this tutorial but would like to create code for the ESP32 to control NeoPixel matrix LEDs. Is anyone familiar with that?

what does the 516 errornumber do?

Hi mo_thunderz, thank you very much for the tutorial but I have followed all your steps and I can not connect with the esp32, it is synchronized because the esp32_Control the android mobile disappears from the screen but it does not mark the status and nothing is seen through the serial port of arduino ide. If I eliminate the block of errors in the inventor app, it appears in the mobile error 515 not connected to bluetooth device.

how can l send more than 1byte??

🌹

can esp32 use bluetooth password in this case?

good
