Advanced Features and Settings
10.1
System Timers and Auto Connect Timers
There are 2 timers that can be used to put the module to sleep, and perform a wake up.
If the sleep timer is enabled, the module will automatically go into deep sleep, low power mode once
the timer counts down to 0. The sleep timer is disabled if the module has an IP connection, or the
module is in COMMAND mode. The timer is reset when characters are received on the UART.
The sleep timer is set with :
set sys sleep <time>
time=decimal in seconds.
The wake timer will bring the module out of deep sleep.
The wake timer is set with:
set sys wake <time>
time=decimal in seconds.
For example, if you wanted the module to wake up, join a network and be available to accept TCP
connections for 30 seconds every 2 minutes you would set the timers as such
set wlan ssid my_net
set wlan passphrase my_pass
set sys sleep 30
set sys wake 90
save
reboot
UDP sleep, and Connection timers
There is another timer than can be used to put the device to sleep.
In UDP protocol mode, the autoconn timer is used as an auto-sleep timer.
Upon the start of transmission of the first UDP data packet this timer will count down.
set sys autosleep <value>
UDP mode: sets the auto-sleep timer. 0 disables
the timer is decremented every xx milliseconds, based on the value of the comm flushtimer. Using a
minimum value of 2 (when the default flushtime=10 ms) is recommended to ensure
that the UDP packet gets transmitted. For larger packets the value should be increased.
In TCP-Client mode, the auto-conn timer is used as a connect out timer. If set, the device will
automatically attempt a connection when the timer expires.
set sys autoconn <secs>
In TCP-Client AND TCP-Server mode, there is also a disconnect timer.
set comm idle <secs>
sets the idle disconnect timer. This causes a disconnect if no transmit or
receive data is seen.
