​@@DIYTechRush How to use mouse and keyboard esp 32

[@flaviodasilva4185]

Thank you. I have been trying to do this for days until I found you! Keep up the good work. You are very good at explaining. I would love it if you did a video to do the same thing you did here, but instead communicate via Bluetooth Classic with a PC using Python.

[@DIYTechRush]

Glad I could help!

[@JimmyDeLock]

Dude, finally succeeding at your tutorial is so encouraging. Makes me feel like this is actually possible. Thanks for your help!

[@DIYTechRush]

Nice work!

[@sdouba]

Thank you for clear, yet concise instructions.

[@DIYTechRush]

Glad it was helpful!

[@johndee7603]

Just tried this, awesome work, love the Bluetooth app to test code, save me a heap of time.

[@DIYTechRush]

Great to hear!

[@farellalvaro8392]

what about connecting esp32 bluetooth to PC? In your case, connecting esp32 bluetooth to terminal bluetooth as slave. But what if connecting esp32 to pc (Master - master)?

[@AhmedHamdy-ik3lg]

Thank you so much for this and i just want to ask about using both wifi and bluetooth in the same program but there's an error indicating that I'm using 117% of the memory size

[@JoshuaAlexThomas]

you explain it very nicely and in a understandable way ! Thank you

[@DIYTechRush]

Glad you liked it

[@malikthetalentmaker6001]

It's good to see you again

[@DIYTechRush]

Thanks man

[@pit5300]

Very well explained. Thanks for taking your time to do this, appreciated.

[@reyanshniranjan9147]

Hi can that esp32 send some commands to another board like a microbit having ble

[@jasonjefferson6596]

I love your channel and pace 👍🏼🙌🏻

[@DIYTechRush]

I'm so glad you like it

[@GaryParkin]

Thank you so much. This worked perfectly. I had to pair the phone first before going into the terminal. (I was wondering why I didn't see the devices in the Bluetooth app.). I was able to use the external LED's we created in the last lesson. I don't yet know what I'm going to use the ESP32 for, but I'm truly surprised at what it can do.

[@DIYTechRush]

Glad it helped

[@khadija5703]

Do you have a video that explain how to use BleScanner?

[@sravankumar4133]

Bro problem with the connection error cant turn on the blue light after uploading help me with that

[@vaclavmarek-tw9td]

Hello can I enter MAC adres of another esp32 device and connect to it through bluetooth serial. I need two esp32 or one esp32 and one measuring device to be connected with bluetooth serial

[@NessaDsilent]

How to create a flutter flow project that a Bluetooth connection with an ESP32?

[@madhavdivya]

Nice video. Got a few doubts and am looking forward to hearing from you. What if I attempt connecting with the ESP 22 from multiple phones? If my phone is not connected, can anyone else connect to the module from their phone? Can I establish communication amidst a master ESP32 and two bluetooth slaves, also ESP32? The connection amongst the 3 devices should happen only amongst themselves every time they are powered up. Can it be done?

[@ikif81]

How I send '1' or '0' to esp32 by Bluetooth from PC (win11) ?

[@Tarou9000]

Excelent, but how do i know if the is no message being sent? in other words, make an action only when a message is sent

[@csil2863]

Your video is very good and helpful. I I used your program as a basic framework for sending a value to my phone by Bluetooth. There is nothing else in the program yet it uses 76% of the program storage space. When I try to incorporate that into another larger program, it exceeds the storage space and will not compile. Any suggestions?

[@AustenSolvie]

It is a bit late but I am running into this same issue. Your best option, if you want to stick to arduino, is to have a board that is dedicated for handling bluetooth and then sending any data over to a secondary board. Adafruit sells some boards with a bit more program storage space but the arduino support is still in development. You could also try esp-idf but that is C and it is kind of gross.

[@melvin-rh2gr]

@Enjoy Mechatronics : Can i restrict only 1 device can be connected to esp32

[@ernestorivero9909]

Conoces algun esp32 mas pequeño que este que tenga bluetooth clasico

[@sunilyajamanam]

Hi, i am beginner to esp32. I am trying to transfer file to sd card in esp32 development board using react native programming. is there any process to do so without any ftp or TCP or web server. please do guide me in this project. Thanks in advance.

[@lhl-channel1894]

When i use 5v of battery for the esp32,i can only connect to the esp32’s bluetooth once an after a few second its disconected and no longer show in my bluetooth setting,can you help me fix it.Thank you

[@messix1030]

so does the usb wire need to be connected to the esp32 or will my solar panel will support the esp32 and eventually my sensor providing live feed to my blynk app. need help mate asap...

[@arreguinjassodianapatricia1584]

Realice todo el procedimiento y no aparece en la lista de dispositivos bluetooth, no aparece el nombre asignado

[@timburroughs2109]

Does anybody know why I can't get the Blue Tooth to work with the ESP32 Node32s? It will not work with an ESP32 Wrover either. I think I am missing a library file. Does anybody know what that might be?

[@КатринБеева]

how to make it via Bluetooth (when the device is close to the other to turn 1 and when far 0)

[@cihankomurcu9423]

Which library for BluetoothSerial

Bro I have an apple phone which app should I download

[@ioanniskousidis2403]

Γεια σας έχω μία ερώτηση έχω μία ζυγαριά που δουλεύει με bluetooth μπορώ αυτή την ζυγαριά να την συνδέσω Μέσω bluetooth με ένα esp32 Και να μου στέλνει μήνυμα μέσω sim στο κινητό μου για τις πληροφορίες της ζυγαριάς;;;

[@Ravenseyes10]

Can you enable Bluetooth so the ESP32 can run WLED from the app on your phone without being connected to a network?

[@jeantedesqui6392]

Very cool! I'm trying to do an anti-lost smartphone project using ESP32 and a small box that will vibrate in the person's pocket if they move away from the smartphone to the point of losing the Bluetooth connection with the ESP32. What changes should I make in this code to make my project work?

[@ap900]

Question: I'm trying to setup my ESP32 to be battery powered. When I have the ESP32 powered through the USB port, I can see the bluetooth device on my phone. When I have it powered to the battery pack (red wire to 3v3 and black wire to ground), the device turns on, but I can't see it as a bluetooth device. Am I missing something? Do I need to change the coding somehow?

[@DIYTechRush]

Use a 5v battery with enough current and connect it to vin pin and ground.

[@TheJavaSync]

I watched another video, ESP32 BLE micropython (& unfortunately it dioesn't work for me, my ESP32_BLE doesn't detected by my phonecell) , why in Arduino it seems more simple (& hope it will work for me) 😅 Thank You!! ❤

[@my88k-mrr98]

Libraries are the center stone of the IDE. If you don't tell people how to get the Bluetooth.h they cannot compile the sketch. Also the ESP32 boards are not the same. Your Board has to be compatible with the Bluetooth.h file installed on the IDE. If your board is not compatible with the Bluetooth.h stored then the IDE will error stating Bluetooth.h not found. What it means is a different Bluetooth.h file is needed for your selected board. Knowing which ESP works with the Bluetooth.h file you have is key.

[@DIYTechRush]

Thanks for pointing that out!

[@6088_VaibhavS]

THE ESP32-BT is not shown in my other devices but i can see it in my pc. Also plz help the IOS users with a suitable and similar application

[@tbbricks4627]

very helpful ! , thank you :)

[@DIYTechRush]

Glad to hear that! ☺️

[@icarossavvides2641]

Better to use if/else.

Nice tutorial

[@lollyispolly522]

[@iamhemanthsai2035]

Me too ooo

[@gabrielbianchi2246]

Can I use this to control a relay that is attached to a 12v solenoid? I want to use this as a controller that I can send info from my phone and then act on the solenoid for a different amount of time, depending on what I send.

[@madhavdivya]

Yes, that should be feasible, drive the output through a transistor and Power the solenoid through a 12v source. Ensure the grounds are made common.

[@Nichbreakdown]

thank you so much works great

[@DIYTechRush]

Glad it helped
