[FLUTTER] control Arduino with Bluetooth module

[@sihebi973]

This is the first video I see that implement this functionality with flutter. I will definitely try it out.

[@AangContreras]

Great! More Arduino-Flutter videos, please!:D

[@MMROBOTTECH]

of course you can also try this video kzbin.info/www/bejne/eIWronitltaGeZI

[@StyleEazy]

work perfectly, thank you !

[@linzantonvacaordonez1746]

Hello brother I loved the project you did, I did the flutter thing it came out perfect but I have a problem with the arduino, it would be great if you shared the arduino code and the connection you made please

[@6thgearup]

Is there a way to use the Flutter Blue instead? This would allow for IOS support along with Android.

[@Marc-mp6lf]

I try to copy the dart files to a new flutter project and add dependencies but i got many errors. How can i copy it properly.

Can we implement _onDataReceived method into multiple classes or..how to get bluetooth data into multiple classes

[@lawsonbuabassah6776]

Hello, I tried implementing the Bluetooth connection between the Flutter app and an HC-05 module using the flutter_serial_bluetooth plugin. Everything works expect I’m unable to connect to the Bluetooth module. The apps keep pending on “waiting to connect…”

really helped me a lot I had success with this code

[@harshaokin8064]

hii. so we have a flutter based app to control an Arduino powered RC car through HC-05. but we need the car to send information back to the app. we're stuck. can you help? we have a metal detector in the car and we need that digital high output to come to the app somehow. and display it in the app. it would really help if you could reply or guide me with some relevant links. thank you

[@bennguyen1313]

Just curious, when you write a flutter application do you have to maintain a different code base for each target, say Android vs Windows? For example, a desktop target would need to use the functions in serial_port_win32 (formerly serial_port).. but an Android app would need to use flutter_libserialport (or usb_serial, tcnserial, etc)? I'm interested in creating a windows application that talks via a COM port to a bluetooth (RFCOMM) transceiver (ex. CP210X, HC-05, etc).. on the other end is a Android device that it's (bluetooth) paired with, also running a Flutter app. Can the same package be used for both Windows and Android (ex. flutter_bluetooth (formerly flutter_bluetooth_serial)), or will they need to be different.. ex Android needs flutter_blue (flutter-esp32-bluetooth)? Also any thoughts if a Windows application can be compiled using VS Code + gcc/mingw.. or is Visual Studio 2022 the only way for Flutter to target Windows?

[@MMROBOTTECH]

I think the same package is just for Android but fortunately there are other packages that can help you just try to do some search. Also I have no idea if a Windows application can be compiled using VS Code + gcc/mingw..

[@marjono123]

unfortunately this flutter_bluetooth_serial dependency is now depreciated, is there any way to still use it?

[@muhammedzekeriya92]

thank you very much ,its really helpfull.

Glad it was helpful!

hi can we connect via esp32 ?

[@theguy2887]

Hey man can i use HC-06 module?? Thanks

[@MMROBOTTECH]

hey , no man you can use it but you should make a simple change in the arduino code like changing the band width [ Serial.begin(9600); ].

[@devisuresh8264]

Hello..Your code is what i am using to understand how to send data but some part are hard to understand. Is there some way to contact you through email to clear up some of the code? I basically just need to send sensor data thru hc05 to flutter app and display it on a screen.

[@MMROBOTTECH]

of course you can, here is my email [e-mail] the thing is that i dont have much time because of my Study but i will try my best.

how to combine it with blockly or scratch（visual programing）

[@MMROBOTTECH]

I used Flutter and java because there is no Video about the topic, but if you want to make it with visual programing there is a lot of videos about it and that is why I didn't make it with visual programing. I cant suggest videos for you if you didn't find anything useful

[@dongyan2905]

Thank you for your reply，i mean theres no implement for visual programming with flutter,if you can do it with flutter,that will be very amazing

[@dongyan2905]

scratch for arduino with flutter

[@MMROBOTTECH]

there will be many Flutter video in the future and I will try to make some of (scratch for Arduino with flutter)

[@dongyan2905]

That would be very nice of you,and I will always follow your progress,thank you for sharing this great video!

How can i edit it to add some features and upload it to play store?

[@MMROBOTTECH]

u have the source code, so u can reform the code to be able to work on your project

communication between phones can be via internet but with Arduino we made it via Bluetooth , so its better to use internet between phones

I'm supporting in this app only android sry man :(

[@nelsonlee9859]

from your Arduino program, may I know how to read data from Bluetooth, looks something missing many thanks, int ledPin = 13; int cmd = -1; int flag = 0; void setup() { pinMode(ledPin, OUTPUT); digitalWrite(ledPin, LOW); Serial.begin(9600); } void loop() { if (Serial.available() > 0) { cmd = Serial.read(); flag = 1; } if (flag == 1) { if (cmd == '0') { digitalWrite(ledPin, LOW); Serial.println("LED: off"); } else if (cmd == '1') { digitalWrite(ledPin, HIGH); Serial.println("LED: on"); } else { Serial.print("unknown command: "); Serial.write(cmd); Serial.print(" ("); Serial.print(cmd, DEC); Serial.print(")"); Serial.println(); } flag = 0; cmd = 65; } Serial.flush(); delay(100); }

[@MMROBOTTECH]

good question, if (Serial.available() > 0) { cmd = Serial.read(); //that code mean that, if there are any message from the app read it and storage it into cmd.
