The above diagram shows the transitions between the Sleep state and Awake state based on the
sleep and wake timers.
10.1.1
UDP Sleep and Connection Timers
In UDP-only protocol mode (set ip proto 1), 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, after which the
module will go to sleep.
set sys autosleep <value>
// UDP Only mode: sets the auto-sleep timer. Setting value=0
disables autosleep timer
The UDP auto-sleep timer is set using two variables. The timer interval is a product of the autosleep
value and the comm flush timer (in milli seconds). The timer is decremented every “product”
milliseconds.
For example, if you need a UDP sleep timer of 40 milli seconds, you need to set the following
variables:
set sys autosleep 4
// Sets the autosleep value to 4
set comm timer 10
// Sets the comm timer to 10 ms (default value)
The resulting UDP sleep timer will be 4*10 ms = 40 ms. You can also use a combination of autosleep
= 2 and comm timer = 20 ms to achieve the same effect.
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.
