Although we normally use the AVRDUDE tool to program the devices, our original .HEX has been successfully tested on the AVR Studio simulator.
Our original .HEX file has 8 kB, leading us to believe that you may have downloaded the HTML page rather than the raw file.
To correctly download the file you need right-click the Raw
button and choose the Save As...
option using the link bellow:https://github.com/BITalinoWorld/firmware-bitalino/blob/master/prebuilt/main.hex
Another option is to left-click Raw
button, copy all of the content shown on the browser and paste it to a text editor from which you then save to .HEX.
Hope you found this information to be useful; do contact us for any further question you may have.
