10. Advanced features and Settings
This chapter describes the advanced features of the WiFly module. It describes the techniques to put the
module in sleep, wake up from sleep and methods to open a TCP connection when awake. We also discuss
the uart flow control, alternative GPIO functions and Real Time Clock.
The table below describes the possible methods of putting the module to sleep.
Drive GPIO 8
To wake up the module from sleep, following options are available:

Get into command mode using $$$ and issue the sleep command
Puts the module to sleep based on the set sys sleep <secs> command
Puts the module to sleep as soon as GPIO 8 is held HIGH (4 µsec latency).
To enable this feature, use the set sys trigger 0x20.
You can wake up the module on sensor pins 0-3 (1.2V ONLY). Use the set
sys trigger <value> command to enable.
The RX pin on the RN-134 and the RN-174 development boards is tied to
sensor pin 0 via a resistor divider network.
Use set sys trigger 1 command to wake up on RX data.
NOTE: You may drop the first byte of uart data. A better way is to wake up
the module on CTS pin.
The CTS pin on the RN-134 and the RN-174 development boards is tied to
sensor pin 1 via a resistor divider network.
Use set sys trigger 2 command to wake up on CTS.
Wakes up the module from sleep based on the set sys wake <secs> command
Input pulse of at least 31 secs duration (3.3V) will wake up the module.
