    convert the hexadecimal code ... into text
    Can you give an example? What is the hexadecimal code? Is it a String: "41" which would convert to "A"
    If you don't understand my answer, don't ignore it, ask a question.

    hi Norm !!!

    Let me explain exactly how our project works.
    we are using pic16f877a microcontroller, we will be transmitting hex values from the pic via bluetooth.
    now coming to the android app, we want to create the app in such a way that it will receive this hex value via bluetooth, display it and then read it.

    The hex value is for individual alphabets and not an entire word.
    eg if i want to display A ,

    The hex value ie 41 will be sent via bluetooth to the phone and now the app needs to detect it and display A.
    once a whole word is displayed eg,APPLE then the app should speak it out !!!

    Please do help us !!!
    Thanks and God Bless!!!

    If you have a String of hex characters, take them 2 at a time, convert the 2 letters to an int (using Integer class's parseInt()) and cast that to a char.
