For example, in order to read the results of a Wi-Fi Passive Scanning that returned 6 MAC Âddresses in Basic Results format,
the user shall send:
The result data will be sent in a stream of 6x9=54 Bytes.
The maximum number of Bytes that be read from one WifiReadResults( ) command is 1020 Bytes. Therefore if the size to read
is greater than 1020 Bytes, the read operation shall be separated into two requests.
10.3.6 WifiResetCumulTimings
WifiResetCumulTimings( ) allows to reset the Wi-Fi Passive Scanning cumulative timings (refer to 10.3.7
WifiReadCumulTimings).
This command shall be called prior to the executing the Wi-Fi Passive Scanning, in order to initialize the Wi-Fi Passive
Scanning cumulative timings if those are to be read.
Table 10-13: WifiResetCumulTimings Command
10.3.7 WifiReadCumulTimings
WifiReadCumulTimings( ) allows to read the Wi-Fi Passive Scanning cumulative timings, coded on 16Bytes, coded as in Table
10-14: Wi-Fi Cumulative Timings Description. The Cumulative represents the total time in he various modes during a
WifiScan ( ) command, therefore summed up for all Wi-Fi acquisitions, over the different WifiScan ( ) parameters (Wi-Fi
Types, Wi-FI channels, ...). These timings are expressed in microseconds.
This cumulative timing can be read regularly to compute the energy consumption of the device for Wi-Fi Passive Scanning
operations. All 16 Bytes shall be read. Cumulative timing must be reset by the host.
