Build Realtime Apps With The Real-Time Network - the mbed PubNub API+SDK
The PubNub library enables your mbed board to communicate with the world via the PubNub cloud messaging system.
The library provides a PubNub class that is tied to a particular set of keys and offers methods that correspond to the appropriate API methods - publish, subscribe, history, etc. The JSON encoded messages are passed as raw strings to conserve memory, but at your option, you can use e.g. picojson library to deal with JSON. The API is synchronous - use multiple rtos threads to talk to PubNub on the background.
