Arduino not working after upgrading from MATLAB 2012a to 2013b.

I was earlier using ARDUINO mega with matlab 2012a and simulink which was working fine. I few days back upgraded it to 2013b. Now after adding support package in matlab(from ADD ON option)matlab is unable to make connection with board. I tried with arduino IDE where i observed that sketch is uploading successfully but no tx rx blinking and no execution of the sketch is observed. Board is working fine when tested with ide on other computer. I am using core i5 with win7

Your help in this matter will be highly obliging

You need to use by Giampiero Campa Legacy MATLAB and Simulink Support for Arduino between Matlab Arduino 2006 and Matlab Arduino 2013

Answer for Error using arduino (line 104) Warning: Unsuccessful read: A timeout occurred before the Terminator was reached.

The answer is: 1 In the Arduino software(IDE). You need write the code, which you find in file "adioes.pde" There are three files adio, adioe, adioes. A for analog D for digital I for input O for Output E for encoder S for Servo. If you need a Servo o a encoder, you need put the code more complete adioes. 2 Compile this code and send to arduino. Close the IDE 3 To open matlab and to write a=arduino("COMxx") 4 You has finalized the Arduino instalation 0 Comments
