bluetooth problem

Hello, I am using code in C for Arduino. The slave device for the bluetooth pairing is sending out an extra variable, the extra variable we cannot find in the code, any help or ideas pertaining to my issue would be appreciated. (sorry if this is the wrong section I thought it was most fitting)

Thanks, Jake.

What bluetooth module are you using, and do you have any code to show?

If you are using Serial.println(), be aware that it sends character 13 and character 10 at the end of the print. So,

Serial.println("aaaa");

will send 'a','a','a','a',13,10

Many receiver routines assume that only character 13 will be received. Adding code that just skips (ignores) character 10 sometimes resolves this problem.
