Hi.

I need to find a LEGO Mindstorms coder.

I build holonomic robots to remote control over the internet.
I control them with a android app called RoboCam.
https://play.google.com/store/apps/details?id=ru.proghouse.robocam&hl=en_US[^]
The RoboCam app is coded with LEGO Developer Kit.
MINDSTORMS EV3 Developer Kits – Support – LEGO Education[^]

I have decompiled the RoboCam app and have its source code.
I send command to "MailBox" in the LEGO robot EV3.

The RoboCam make the phone to a server and create a website that listen to key pressed, mouse and so on, and send then a drive command, by Bluetooth , to robot.
Is it TCP/IP or bluetooth I need to search for ?


My question is......
I try to remote control the robot from my own website in PHP.

So how do I find the code, that sends a command to the robot, in the source code.
What words do I use, to find the command control code, that I need to write in my PHP code, when i detect a key press, in my PHP website, that make my robot get a engine run command?

I have tried to search with words like
