2. Wake Timer: Used to wake the WiFly module from sleep<br />
3. Auto-connect Timer: Used to automatically open a TCP connection<br />
4. Idle Timer: Used to automatically close a TCP connection<br />
There are 2 timers that can be used to put the module to sleep, and perform a wake up. If the sleep timer is<br />
enabled, the module will automatically go into deep sleep low power mode once the timer counts down to 0.<br />
The sleep timer is disabled if the module has an IP connection, or the module is in COMMAND mode.<br />
The sleep timer (which is the time the WiFly is awake) is a 32 bit number of seconds so it can be as high as<br />
1.19 million hours.<br />
The wake timer (which is the time the WiFly is asleep) is a 22 bit number of seconds so the maximum<br />
sleeping time is 1165 hours.<br />
The sleep timer is set with : set sys sleep time=decimal in seconds.<br />
The wake timer will bring the module out of deep sleep.<br />
The wake timer is set with: set sys wake time=decimal in seconds.<br />
For example, if you wanted the module to wake up, join a network and be available to accept TCP<br />
connections for 30 seconds every 2 minutes you would set the timers as such<br />
set wlan ssid my_net<br />
set wlan passphrase my_pass<br />
set sys sleep 30<br />
set sys wake 90<br />
save<br />
reboot<br />
The above diagram shows the transitions between the Sleep state and Awake state based on the sleep and<br />
wake timers.<br />
