Hello all

Is it possible to use SImulink to make an app that allows android and arduino to communicate with each other via an USB-OTG cable ?

I understand that there is a serial receive and send within the Arduino support package.

However, there is no such block within the android support package.

I would like to see if this is possible directly, or is it always necessary to create a separate application that runs in the backgroun to send and receive the serial data?

Cheers !

Currently Android Support package does'nt have USB-OTG support, you can use ToApp/FromApp block and implement your own USB communication in Android Studio

Check below examples on how to use fromApp and toApp blocks

Hi Sir Thanks for replying

Will this mean that i will need to make another application to run in the background, in order to send the data through a USB cable ?

I understand that this ToApp and FromApp requires me to edit the generated code in Android Studio.

Cheers

i think it is supported now... I havent done that but there is a Serial send/receive in Simulink suport packages for android. I think that would do the job
