Sending MATX command only gets to Matrix A correctly, B (assume c also) will switch to pattern 0 (all off)

The issue is in this function

void sendMatrix(){  //// Probably here that is issue ?? 
    String buff = string.substring(4);
    char buffer[buff.length()+1];
    buff.toCharArray(buffer, buff.length()+1);
    Wire.write(buffer);
    Wire.endTransmission();
    delay(500);
    digitalWrite(13,LOW);
    string = "";

The last line clears the string prematurely, Its fine if only sending to a single board but in the case of multiple sends the string is gone so we are sending just \0 to Boards B and C.

Should also fix ALLX commands as is very likely the same bug.
