Step 3:
Set the wake up and sleep conditions. In this mode the sleep and wake timers are used to conserve battery. Since
we don’t know when the remote host will connect, the module should to occasionally wake up and listen for the remote
host. The trade off with these timers is that the longer you sleep, the better your battery life will be but the longer it will take
the remote host to connect.
WARNING
:
Do not set the sleep timer below 5 seconds or it will be impossible to get into command mode to
reprogram this mode without it going back to sleep!

4 WiSnap Command Reference
4.1 Command Syntax
Commands begin with a keyword, and have optional additional parameters, generally space delimited. Commands and options
are
case sensitive. Hex input data can be upper or lower case. String text data, such as SSID is also case sensitive.
The first command is fully decoded and must be complete. Other command parameters can be shorted by using only the first
character.
For example,
set uart baud 115200
is valid
set uart b 115200
is also valid
set u b 115200
is also valid
