Need help converting String to int...

Ditch the String object all together and just use the string you already have.

It seems like you only convert it to String so you can use the + operator and charAt member function. Much easier to work with the char arrays:

char num[3];
char pos[4];
strncpy(num, inData, 2);
num[2] = '\0';
strcpy(pos, inData+3);

You don't even need the second array, since you will just be passing it into atoi(), you can just pass inData+3 to it.

You should also extend that char array out a bit. You are using 5 numbers plus a null, so you need 6 bytes, but you only give it 4.
