16.2 How to Use / API

Three commands get the needed statistics. The first command is sl_WlanRxStatStart (), which starts collecting the data about all Rx frames.

sl_WlanRxStatStop(), stops collecting the data.

sl_WlanRxStatGet(), gets the statistics that have been collected and returns them in a variable type SlGetRxStatResponse_t. The command is used as follows:

SlGetRxStatResponse_t rxStatResp;
sl_WlanRxStatGet 
(&rxStatResp , 0 );

The second parameter is flagged and it is not currently in use.

SlGetRxStatResponse_t holds the following variables:

ReceivedValidPacketsNumber – Holds the number of valid packets received

ReceivedFcsErrorPacketsNumber – Holds the number of FCS error packets dropped

ReceivedAddressMismatchPacketsNumber - Holds the number of packets that has been received but filtered out by one of the HW filters

In connection mode:

  • The data is valid only after sl_WlanRxStatStart is called
  • The counter will indicate the number of frames that were filtered out by one of the HW filters – since this is connection mode most of the packets will be based on address missmatch

In Transceiver mode (disconnect mode):

  • The data is valid only after sl_WlanRxStatStart is called
  • The counter will indicate the number of frames that were filtered out by one of the HW filters
  • Configure a filter in the Rx Transceiver (MAC address, frame type and so forth) in order to see this counter incremented

avarageDataCtrlRssi – Holds the average data + control frames RSSI

avarageMgMntRssi – Holds the average management frames RSSI

RateHistogram[NUM_OF_RATE_INDEXES] – Histogram of all rates of the received valid frames. The rates are sorted as follows:

RATE_1M = 0 …

RATE_2M

RATE_5_5M

RATE_11M

RATE_6M

RATE_9M

RATE_12M

RATE_18M

RATE_24M

RATE_36M

RATE_48M

RATE_54M

RATE_MCS_0

RATE_MCS_1

RATE_MCS_2

RATE_MCS_3

RATE_MCS_4

RATE_MCS_5

RATE_MCS_6

RATE_MCS_7

NUM_OF_RATE_INDEXES is 21.

RssiHistogram[SIZE_OF_RSSI_HISTOGRAM] – Histogram that holds the accumulated RSSI of all received packets from -40 to -87 dbm every 8 dbm.

SIZE_OF_RSSI_HISTOGRAM is 6

StartTimeStamp – Holds the start collecting time in microsec

GetTimeStamp – Holds the statistics get time in microsec
