BlueTooth serial data - format

Projects Programming

Hi

I'm trying to work with BlueTooth serial data.

[The code] int inByte = Bluetooth.read ();

But I only receive the format:
49 = 1
97 = a

I want 1 = 1, a = a

Is there an easy and easy way to reverse this

You are receiving ASCII. To convert ASCII numbers to integers, subtract '0' or 48, but a isn't really a number, so it already equals a...

3 
char inByte = Bluetooth.read ();
4

Cast the int to a char.

char inChar = (char)Bluetooth.read ();

Have a look at the examples in Serial Input Basics - simple reliable ways to receive data.
