Function Documentation

int main

(

void

)

Main function of sniffer application.

The main loop of the application processes the input coming from the HIF and frames and frame data received by the radio transceiver.

void scan_update_status

(

void

)

Update status in scan mode.

void sniffer_init

(

void

)

Initialisation of hardware ressources.

This function initializes the following components

• LED Port
• Timer Module
• Host Interface
• SPI Port for Radio
• Radio (reset and enter state RX)

void sniffer_start

(

sniffer_state_t

state

)

Start a new operating state.

Process data received from HIF.

void sniffer_stop

(

void

)

Halt current operation and enter state IDLE.

sniffer_context_t ctx

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.
