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
disablesautosleep 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
setcomm 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 ensurethat the UDP
packet gets transmitted. For larger packets the value should be increased.
10.1.2. TCP Connection Timers
Opening a TCP Connection:
In TCP-Client mode, the auto-conn timer controls the establishment of a socket connection. Whenset, the
device automatically periodically attempts to establish a connection when the timer expires.
set sys autoconn<secs>
This command causes the module periodically connect to the host. The timer <secs> determines how often
to connect to the stored remote host. If set to 1, the module will only make one attempt to auto connect upon
power up. If set to 2 or greater auto connect will re-open the connection after the connection is closed.
Default=0 disables.
For auto connect timer to work, the remote host’s IP address and port number needs to be configured in the
WiFly GSX module.
