Wirelessly download from online compiler onto mbed chip via ethernet.

Parts Needed

1 x Ethernet RJ-45 Module 1 x Mbed and Web Server

Details

Idea: Download compiled program from the online compiler and send it to the Mbed wirelessly using either Wifi or Ethernet. Mbed is automatically reset and the new program is loaded and executed. New library (Wiflash) for developers to incorporate the wireless update functionality into their projects.

ESP8266:

Developed a library to use wifi instead of ethernet to wirelessly download data on to the compiler. However, the libraries in the ESP8266 are not compatible with the mbed library due to issues with the TCP/UDP protocols.

Here is a link to the library we created with more information: http://developer.mbed.org/users/adhithyan15/notebook/esp82661/
