I am receiving 3 different strings and I print them separately based on the first char.

All is well till I tried to parse one of strings by token. The newly formed strings will print out but will not show as text . I get a null pointer.

Please help.

```auto
  if (BTPort.available() > 0) {
    IncomingStr = BTPort.readStringUntil(lf);
    if (IncomingStr != null) {
      First = IncomingStr.charAt(0);
     // println(IncomingStr);
     // println(First);
      
  if (First == 'M')  
   Incoming_Currents_A = IncomingStr; // incoming current string from teensy
   
   else if (First == 'E')  
   {//Incoming_Encs_A= splitTokens(IncomingStr, "B "); // incoming current string from teensy
  
   Incoming_Encs = splitTokens(IncomingStr, "B");
   //println (Incoming_Encs[0]); 
   
   }
   
   else 
   Incoming_Info= IncomingStr; // incoming current string from teensy
    }
  }
  
  fill(g);  
  

    text (Incoming_Encs[0], 10, 1000); 
  text (Incoming_Encs[1], 400, 1000);
 
  text (Incoming_Currents_A, 10, 1040); 
  text (Incoming_Info , 10, 1080);
   
  

```

@laptophead – were you able to resolve this?

It is hard to test this or give feedback with only a code fragment.
