Thank you, I will
Nice bro keep it up

Hi can you do tutorial to display multiple ir sensor and update to the apps using MIT App Inventor? Example parking slot. If slot 1 available the ir sensor send data to the apps and text on the saying slot available. And if slot 2 has been parked the apps will display slot 2 has been parked.
Hi there, I have been working with esp32 display boards but now that I see what can you do with this app builder, I will completely switch over. As I am used to using esp-now,, can the app communicate with WiFi?
why my bluetooth list not showing in listpicker , pls help

I don't know why. I have the same problem...
Same problem I just fixed it. Go to settings >> manage apps >> then make sure the "nearby access" is allowed. Just check the app permissions and allow it.
How to install bluetooth library. Please help...
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 uuid , then connect directly to esp32 . Please let me know if this is right or show a video on how to do this as a refernce
If I use the Serial Bluetooth Terminal, it is working fine. Thanks
👍
Kalo on off menggunakan waktu yang kita tentukan dimit app..ada ga videonya?
I have some error message: no matching function for call to 'BluetoothSerial::BluetoothSerial()', BluetoothSerial SerialBT; Can you help with it please?
Ok, the reason of this, is the wrong esp32, without Bluetooth serial 🤷♂️. On over board everything is fine 😁.
With micropython and ESP32?
i've done this and when I tried to connect the following error happened: error 503 the specified address is not a valid bluetooth MAC adress
How can i automatically connect to a Bluetooth Device?
Hi, why I can not see the list of BT devices on my Android smartphone after press a Devices List button?
did you discoverd why?
Hi, how could this be done to control addressable led?
Yeah, It's possible and I am gonna talk about it soon.
Not working on Android12 or later.
AddressesAndNames:
Returns the list of paired Bluetooth devices. Each element of the returned list is a String consisting of the device’s address, a space, and the device’s name. On Android 12 or later, if the permissions BLUETOOTH_CONNECT and BLUETOOTH_SCAN have not been granted to the app, the block will raise an error via the Screen’s PermissionDenied event.
loving you mate, thank you
Thank you so so much, i was spending about an hour trying to figure out why the Bluetooth wont work. Thank you
The reason Bluetooth devices may not appear when I press the 'Devices List' button on my phone could be due to what? I urgently need it for my internship assignment
Add nearby devices permission from the app permissions
CAN I GET THE CODING?
hey ive made an ultrasonic distance measure, and the output is on serial monitor of arduino ide how do i make the output of serial monior to be produced on the app
Check out in this video:
czcams.com/video/1PoRcb4_wsw/video.html
it has to be connectet via cable to the computer, I can't get it to work with external powersupply WHY??
Why don't I see any bluetooth devices when entering the app? Although I have already connected the HC-05.
Sometimes you have to give the app permission to access nearby devices (for Bluetooth) in the phones settings, find the app you made under app management
@@evanhewitt6847 i was find bug. when i build app on appinventor i will not found device to conect bluetooth. if i use app old a few years ago, i will find it
I have a bluetooth module HC 05 and when I open the application to connect to bluetooth I don't get the list of devices?
Make sure to pair your phone with the Bluetooth module and allow "nearby devices" permission from the app settings
HC-06 Bluetooth device is paired with my mobile. However, no device is showing in the device list.
Maybe you have to add nearby devices' permission to the app from your smartphone
I have a problem trying to connect via bluetooth, I get error 507 and I don't understand why my devices are well connected, if anyone can help me I would really appreciate it...
Hi ,may i know that why arduino nano 33 iot cannot conenct with the mit apps after following your tutorial?

Sir 4 channel will provide a remote control program and app made video I am waiting.
Hi Sir. Great tutorial. But why is it that the mit app cannot detect my esp32 bluetooth device? Please help. Thank you very much.
You may need to add nearby devices permission from the settings of the app.
je bien fait le code mais je n'arrive pas atrouver les elements dans le elementpick1
modifier la permission de l'application
in Arduino IDE code line 16, if i want to have 2 different variables how can i declare sir
You don't need to create another variable c. Just add more conditions like
if(c== '2').....
mit can make ios app?
I have a problem, mine does not detect paired devices. List picker is empty
Add the "nearby devices" permission from the app settings
what about esp8266module?

I see a blank screen when i try to select from device list, I gave the permission to nearby device from settings. still nothing shows up
sameee...

Add the "nearby devices" permission from the app settings.... this helped me solve the problem
hello, i do same with you but when i open app on phone and click ' Device List ' the phone can not detect bluetooth of ESP32 to connect. Can you help me
Before you open the app, pair your phone with the esp32.
@@EnjoyMechatronics how sir, i do not see name of bluetooth from esp to connect
i think since android 13 the permission changed and you have to add a lot more to scan and pair devices... :(
yes it does not connect even on android 12, it just pairs thats it, do u have any solution?
Sir, when I click Device List no bluetooth device shown up,something is wrong but I cant find out. Could you please share your code and app?
I haven't saved the code, but I've created another project with all of the files included in the description

Me too,do you have any solutions to solve the problem? Can you show me.Thanks a lot
