Java/C# Serial port write to Arduino reading wrong bytes -


i have program wrote in java writes serial port have arduino pro mini plugged into. each chunk of data 6 bytes, , when arduino receivies data, spits out console can see that. problem when data spit out, in wrong order bytes appearing sent twice. wrote same functionality in c# , same thing happening. wrote arduino code write data , echo back, , correct.

so problem must non arduino code, or hardware settings. in code, added delay after every write allows data stay correct while, starts getting screwed up.

i tried messing baud rate, didn't help. why happening??

here's arduino code.

//wait 7 bytes come if (serial.available() >= 7) {     /* read recent byte */    serial.print("data: ");    //set enable byte    data[0] = enable;    serial.print((int)data[0], dec);    serial.print(" ");    for(int = 1; < data_size; i++)     {       data[i] = serial.read();         serial.print((int)data[i], dec);         serial.print(" ");      }       serial.println(); }
