Now we are going places!

I don't use String types, and this (among other reasons) is why. I use character arrays.

char readString[20];

If you pass readString as a parameter now, it will work. At least it should. I have not used the .trim() function before, but now I might try it.

You will probably need to redo your ad-a-character routine to that array. Like this:

int charCount;
char readString[20];

// Then in the loop
charCount = 0;
readString[0] = 0;

while(client.available())
{
   char c = client.read();

   if(charCount < 19)
   {
      // store character
      readString[charCount] = c;
      charCount++;
      // set terminating zero
      readString[charCount] = 0;   
   }
}

// If you need to empty the array,
charCount = 0;
readString[0] = 0;

edit: I added the readString zero terminator when I set charCount to zero.
