Hello,
Take one Arduino UNO R3, a Arduino Wifi Shield, a Sparkfun Can-Bus Shield and one Android Tablet.
The server is o the tablet, arduino board acts as a client. I receive data from some height, pressure sensors through the Can-Bus shield and sent it to the Android tablet through the Wifi shield. Note that the tablet also can send commands through the Arduino board/shields.
My problem is that the communication from the board to the tablet is either very slow, it takes seconds to send a few messages, or it doesn't send at all, it simply crashes. It's true that the sensors send allot of information but I don't think it should act like this. Even if i completely remove the Can shield and send a simple string, it acts strange, sometimes it crashes, sometimes works but only for a few seconds, but still laggy.
If you may, any solutions? If you ask I can give any information about my project. Thanks in advance.
