Detailed Description

Interface of the Sniffer Firmware.

Define Documentation

#define CHANNEL_NEXT_CIRCULAR ( x )

Value:

do \
    { \
        (x)++; \
        if ((x) > TRX_MAX_CHANNEL) \
        { \
            (x) = TRX_MIN_CHANNEL; \
        } \
    } \
    while(0)

Increment channel number and wraps back to lowest channel, if upper channel + 1 is reached.

Appication States.

Enumerator:

IDLE	Application is in idle mode, receiving commands from HIF.
EDSCAN	Application is in scanning mode.
SCAN	Application is in scanning mode.
SCAN_DONE	Application is in scanning mode.
SNIFF	Application is in sniffing mode.

void scan_init ( void )

Initialize the scan mode.

void sniffer_start ( sniffer_state_t state )

Process data received from HIF.

The function checks for available input data and performs depending on the current state the processing.

void sniffer_stop ( void )

Halt current operation and enter state IDLE.

Note:: In order to get higher performance in frame receiving, this application uses a own implementation of the transceiver interrrupt routine (TRX_IRQ_vect), instead of the callback function from librf23x.a.
