Bluetooth RC Car Customer Insights

1. Ps would like to have known if it was only Bluetooth in the name plz fix.Yeah it's a good app, for many it is lagging for me too it lagged so I changed the last line of the program where there was def (100) and I changed that into def (5) and it worked without any lagging so anyone who has these difficulties u can try this methodMy car with 4 motors and only the L293d is taking to long to go forward or backward to I tried to use a HC-06 with it and I couldn't connect it using the natural 9600 bauds.

2. Update: To get around this issue I used the horn button in the app and coded the Arduino Nano to set all pins to LOW to stop all motors when the horn button is pressed.Best BT control app I have seen.

3. Is it essential to work on 115200?The app seems like it has potential but it only works with Bluetooth rc cars where can I get one? Never heard of one but the reason I said it has potential is because it does not hook up to non Bluetooth rc cars but hope in the future it can hook up to non Bluetootooth cars.

4. Horn button currently has ON/OFF toggle option and it would be nice to hav a push-ON and relese-OFF type like in Forward/Backward buttons 2.

5. But if you can please make the user interface a little more interesting I would appreciate it moreVery good app with a very easy to understand base program, with some modifications to the program it's easily to match any vehicle.

6. Tank for example, only needed 1 DC motor drive with 2 motors.I really like this app, Im suggesting if we can also manage to costumize the layout.

7. It will be nice to have a key send when connecting app to BT also.Hi Andi, I'd like to thank you for your efforts done in that project and sharing your knowledge.

8. May I know what code is sent when we press "triangle" button ( emergency symbol).

9. Thank youHi, I am using your app for my bluetooth RC car.

10. Using the Monitor Window I can send instructions and doesn't take too long.

11. I have an HC-06 BT device connected to my robot with an Arduino Nano.
