WiFi Module
The optional WiFi module is an XBee-format module with an integrated antenna an “AT
Command” style interface. The part number is RN171XVW-I/RM. It may be ordered from
Thingmagic as part number XP-WI-FI.
WiFi transport will be used as the output interface only if neither USB, Bluetooth or PoE
are active (unless you modify the application program to use different logic).
To enable the WiFi output interface, the user may need to modify conf_xpress_reader.h
to disable other modules which are using the same XBee slot. The required modifications
in conf_xpress_reader.h are
1. Enable WiFi output interface by un-commenting
#define ENABLE_OUTPUT_WIFLY.
(It is un-commented by default)
2. Define the UART interface to be used for WiFi module using WIFLY_DEVNAME and
this depends on XBee slot being used for WiFi module (e.g., #define
WIFLY_DEVNAME "/USART1" )

Slot - 0 is used with USART1 (This is the default)

Slot - 1 is used with USART2
3. If they are present, disable other modules which are using the same UART defined in
above step.
