    Hi friends,

    I just playing with bluetooth device. All communications are working. Now I want to build a bootloader application to flash my AVR microcontrollers.

    When I send a byte upto 127 all works fine. But if the microcontroller send a 128 I receive a "-90"... Where is my error?

    Cheers
