BLEduino for Arduino 1.6

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:

processing.app.SerialException: Error touching serial port '/dev/tty.usbmodem1421'.

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.

DHT22 Temperature Sensor with Bleduino


About a year ago I pledged $39 for the Bleduino kickstarter and despite it arriving on my mailbox a few months ago, only today did I have time to start playing around with it. I also got a DHT22 temperature sensor, which I will use with the device. A quick disclaimer, I’m a beginner in Arduino and electronics and would describe my soldering skills as non-existent. Hence you will find no soldering in this post.
