Is there a cross language standard? Ie C++ to Java over serial? : <p>For my project, I am creating an Android GUI app to control settings on a Arduino. There is a USB OTG cable bridging the smartphone and the arduino. At the current state, the arduino replies back strings that were initially sent from the App to demonstrate successful communication.</p>

<p>However as the app will allow the user to changing settings, I was wondering if there is a guideline to help with moulding this communication between the two languages?</p>

<p>At the current time, I visualized that I could facilitate this communication by setting a certain word for certain settings then followed up by the number to set the correct setting.</p>

<p>Ie, 50 second timer could be designated by TIMER50S which allows the arduino to parse the string and decipher that the timer needs to be set to 50 seconds. </p>

<p>I was wondering if there was a well established standard to communication protocols like these?</p>
