Just a tiny update, I received two new boards in the last 3 weeks. That's why I haven't got time to write more tutorials, neither to port some freedom boards. More you want to achieve, less time you have left :)
The first board was the application mbed board, very first NXP chip on my desk. I tested mqtt which did not work due to server problems, some ethernet applications. I'll get closer look at mqtt in the upcoming weeks.
The second board was the Wi-Go board (cc3000). It is already supported in mbed although cc3000 is not complete yet.
I am currently rewriting cc3000 driver and will be available on mbed soon. I'll share more with you later.
