LAUNCHXL-F28379D: SCI Communcation Problem with Matlab

Hi everyone,

I have a problem with MATLAB to transmit/receive data. Actually, considering transmit, everything is OK. But, receiving block does nont work perfectly. Because, I couldn't read whole data which I sent. Although I just want to read 100Byte data, it only reads 15Byte. I shared my problem below as a picture:

when functions commented out, display shows the data package

when functions are working displays won't work

when scope working connection goes timeout.

Thanks for everything.

Sincerely,

Fethi.
