P prochip New Member Licensed User Longtime User Jun 5, 2015 #1 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 Jan
