Hi Mellis,
Thanks but that does not answer my answer completely. The code for the bootloader is in .c and that is not understood by the Arduino compiler.
I have been trying already with AVR studio under Parallels. I compiled the bootloaderfile .c file that comes with Arduino0011 (with an extra command in it) and uploaded the .hex file to the controller using Arduino0011. It worked but not convincing. That is. I can see that the extra command is sent through the serial port, but the LED is not blinking and I think that is part of the bootloader as well. Furthermore my Bluegiga does not seem to respond to the commands (I turned autocall off but it is still on).
Is this a proper way to do it anyway?
Best, Hans.
