Controlling an RC car with an ESP32 and the MAE (Mit App Inventor

@the-legend You said

the "DISCONNECT" button immediately after starting the application is disabled.However on my app, the "DISCONNECT" button immediately after starting the application  is enabled

It's probably a difference in either an external pull up/down or the pinMode statement. 

@zander 

hi !!!

hope you are doing great!!

I don't think it is the Arduino code that is the problem.I think but the MAE code is.(I may be wrong)

Could you please take a look at the MAE code?

Thanks So Much!!!

@the-legend No. Post the code here, I am not going to click a link or sign up for something.

@the-legend I downloaded the two ino files. They compile fine, and I see no connection to an MAE 'thing'.  This code was written by someone else and since it compiles then if it does not do what you expect, the design is wrong and that is impossible for me to comment on since I am missing 100% of the needed information.

You need to explain what should happen, and what is happening as if you were talking to a 10 year old.

If you can eliminate the MAE thing from the problem description that would help as this is NOT an MAE forum. Since it appears to be associate with MIT I would assume it is NOT the problem, and if it is an existing 'thing' that also suggests others are using it with no difficulty.

The bottom line is you seem to want help with things you did not create and others may be using with no difficulty. I think you need to re-frame your question possibly with simpler code and setup.

I watched a bit of the video. Now I think I understand what the MAE thing is, it appears to be similar to the Arduino cloud. Since we only support Arduino cloud here and not MAE, I think you should get your support from either the video author, or the MAE community.

Good luck.

@Muhammad, I tried doing the same thing you are trying, but I ran into issues between classic bluetooth and BLE. This may not help you, but I switched from bluetooth and went to WiFi control instead. There are a few YouTube vids with others doing this. Here's a couple,:

I used the MIT App Inventor and with lots of research was able to get it to work. I used an app I downloaded from Google Play store like the guy in the vids uses. 

I'm in the middle of something right now, but I wanted to reach out with the above links. I will also try to look at your code soon to see if I can help, but right now the above is what I have.

Hi,Thanks for your feedback.I much appreciate it!

Thanks a ton!!! 

Hi,

Hope everyone doing well !!!

Thanks to everyone who tried to help me with my project.

After looking at some of the posts I modified the code and finally completed the project. 😊 

I look forward to making more fun bluetooth projects in the future !!!

Thank a ton!!!

@helisteve I would never use any kind of Bluetooth if I could avoid it, just too unreliable. ESP-NOW is a MUCH better solution.

@the-legend , did you stick with Bluetooth, or switch to WiFi?  Whatever you did I am glad you got your project working. That's always a great feeling.

@zander 

I know. I am just getting started. This is one of the first projects I made so I am just trying to get my project started by doing the easiest thing😜 . I know it is not very effective. I am trying to expand my knowledge with coding and maybe later,  I can integrate my project to work with ESP-NOW.

@helisteve

Thanks !!!

I stuck with bluetooth. It is a great feeling that I completed a project !!!

Maybe later, I can expand it to work with WIFI or ESP-NOW.

@the-legend , so glad to hear you got it working. It is a great feeling when you struggle and then figure it out. Give yourself a pat on the back, and enjoy your project.
