connect() now returns true/false depending of the return string from the WiFly
Added WiFlyDevice::getConnectionStatus to check if we are still associated and authenticated to the network.
To allow re-joining a network in case we get disconnected, avoiding the strange issue that prevents using join after using sendCommand, call begin() inside join().
Adopted some code from brandenhall fork, to keep track of command mode in enterCommandMode / exitCommandMode.
Sending the commands in chunks seems to work unexpectedly. Building the whole command before sending seems to be a better approach…
Work in progress, will need some code cleanup if this finally works, so far we can avoid sending a begin() before reconnecting.
Some code cleanup and changing the approach definitively for join(), sending the whole command at once. This makes possible reconnecting if the network goes down.
New feature: Set system sleep and wake timers.
Updated README.md
Added sleepNow() method to send the WiFly to bed inmediately.
Added example to send notifications through Notify My Android service (http://www.notifymyandroid.com)
Added method to use UDP communications.
Added readTimeout method to read directly from WiFly (with a timeout). Interesting for UDP and OSC apps.
Added readChar() method for convenience.
Added a simple example to send data to Thingspeak (Internet of Things) servers.
Merge Sparkfun/master with ejorreto/WiFly/master to add my own improvements and continue from here.
