I want real time reading, can you please tell me, how to change the code to get it

[husseinalsayedali]

Hello how did you pair your mobile with the module from your phone settings, I can't do it and displays a message "An app is needed to use this device " every time I try to pair with it

[goncalofigueiredo]

I always get the message “Unable to connect to the BT device” and it doesn't show me the values obtained with the Arduino.
Do you know why I get this error (the search devices works and the connect button is activated)?
I really need help!

Thanks for sharing this project.

I am new to android studio java programming and I am stuck behind startActivityForResult which has been deprecated. I don't know how to get around this problem. Thanks in advance for your help.

hiii this is shruthi...have a doubt that here you have displayed one sensor right! I connected multiple sensors with arduino ...so I want to read all that sensor values means, where can i modify in this code...can you explain

[mountrat]

So, at the beginning of the connection, you enter ah passkey right? Does it related to classic bluetooth?

So is passkey based Auth possible on BLE?

And can u plz let me know how to perform esp32 based android app for BLE and I need the passkey based Auth?

[fackaable]

Good tutorial.
Maybe you should have a function that refreshes the readings every 10 seconds?

[trungtrung]

i get the error "read failed, socket may close or timeout, read back: -1" when i click "connect" even though i have connected HC05 before. May you help me?

[wesley-_soaus]

Hi! what's up?! is there any way to connect the app to a HC-06(bluetooth model) and receive data from a RFID tag? i would appreciate very much if you could help. Thanks!

Oye que lenguaje usas kotlin o java? distinguí que hablas español puedes decirme? muchas gracias.

[creativearts]

have you uploaded the output stream feature?

[clementbranas]

does this work using kotlin instead JAVA ?

[goozlo]

where is the arduino code? At part 1, you only print the data to serial port, you don't send them to bluetooth

[PrimeMobileLegend]

what is the source code of the arduino?

[lucasianii]

Great video, i need someone to help me build similar app using Bluetooth Low Energy, and in kotlin. Paid job. Just a basic app.

[abdalmahayni]

Hey, very nice viedo, but i have a question .. what if i want to read the values continuously, if the Arduino sent a new value to the device, i dont want to click the button everytime, , should i delete the cancel functions ?
tnx

[SilviaMolero-vx]

Me sale siempre el mensaje "Unable to connect to the BT device" y no me enseña los valores obtenidos con el Arduino. Sabes porque me encuentro con este error? (funciona el search devices y se me activa el boton connect)

[wasouthpnt]

I tried your sample, but because you have these imports I cannot get a build. Could you please explain how to get these libraries into the Android Studio project?

import io.reactivex.Observable;
import
import

That would help me to gain understanding
