App Inventor 2 Tutorial - Android receive data from arduino via HC-06 Bluetooth

Android receive data from arduino via Bluetooth.

In the arduino code, i write 500ms delay, maybe that too much, you can change to
2-300ms.

Arduino code:

its And guys, this is the only proper tutorial in whole youtube for SERIAL MONITORING USING BT MODULES.ONLY 1!!!1 today is my deadline date, and i want to tell you YOU SAVED ME <3

[gurutheone]

Gracias, era el video que necesitaba para mi propio Eureka!! (thanks this video was that i need for my own EUREKA!!!)... I LOVE YOU!!

[yesitasnow]

Thank u so much! It worked perfectly, the problem was in the line Serial.print(" " ); and now it shows number between 0-1023 :)

At 0:11 you set the Text for Label1 pixels at 28. What is the pixels for? and why 28?

I want to play any audio when the value of potentiometer values goes up to 500. What should i do to do this task??

[orkyo]

Sir, I'm receiving multiple values say, [1.78],[20.1] how do I display each of them differently and with >= conditions. Please help.

[hamzarguig]

why you dont initialise your bleutooth communication pins(Rx, Tx)???

[technical_solution]

Sir google drive code is not available can u tell which command do you use in Arduino to send data to App

[michaelasistio]

I followed every steps, but the data didnt show in the android. im already paired with the bluetooth. the data is also showing in serial monitor. help please.

[eddyUMAD]

hey! im trying to print values from my serial monitor to the app but for some reason the values change when i am connected with bluetooth and the app crashes any idea why this is happening?

[davepaul]

I'm NOT using Arduino. Is there a way via AI2 code to hold the TxD line of the HC-06 down for a period of time? (1 to 10 ms) I'm having a timing issue with the device It's communicating with.

[robocoupler]

Hello Sir
I am doing a project as the same, but i want to fix a pot value in app and when it reaches the pot value it has to play some sound or open another screen..., .can you tell how should i do it ?.It will be help full to me if it is done.

[SwarnanEel]

I have a question,
how to align the buttons and labels according to my required position on the screen?
They seem to auto align left to the screen and i cannot find any tool that will help me put them at my desired position.
plz help

[thomaslegacy_h]

Using this I still get the error 507 'is the device turned on', any advice with this?

[panweerasekara]

Hi, I have created the app and when i try to connect with the HC05 Bluetooth module it says "Error 503 the specified address is not valid Bluetooth MAC address" is it because i made the my blue tooth device slave mode? or is it wrong configuration while i m creating the app?

[SettimaLegione]

Strange... I cant hear the audio (if there is one)
Please, explain me were and how you set the incoming value from the BT module to  appair as text in the "Text label". The other settings are clear but I miss this point.

[Sergioax]

Thanks a lot!! :D, Hello from Colombia! this video help me so much!! :D

[icydoll]

how can i split the string like 3600/2500/900/300 which i m getting throug bluetooth module in text label 1
