For the past year or so, my BLEduino laid dormant in the cupboard. Yesterday, I decided to break it out for a new project. While I used Arduino 1.0.x for the BLEduino previously, I now have Arduino 1.6. Unfortunately, I discovered that BLEduino isn’t compatible with it – The hardware core files were for 1.0.x only. I tried to use 1.0.6 on my Mac OS X 10.11, but every time I tried uploading a sketch, the following error occurs:

A search on the internet seems to indicated that this was a bug in the Arduino IDE, fixed in 1.5 later versions. I decided the only way to resolve this issue is if I port the hardware core files from 1.0 to 1.6. Luckily enough, Arduino wiki provides a handy migration guide. Within half an hour, I got BLEduino working on Arduino 1.6. I’ve posted my changes on GitHub, for anybody interested: BLEduino Arduino 1.6 hardware files. Hopefully, someone finds this useful.
