Monitor mode and RX filter
Monitor mode is the mode in which platform can receive all the packets transmitted over the air, call
wifi_config_set_opmode()
to configure the platform in the monitor mode.
The RX filter, which only works in station mode, is able to filter out user-defined packet types. Set the Rx filter, as
shown in section 2.6.1, “How to use the RX filter API”.
2.6.1.
How to use the RX filter API
Set the RX filter control register (RFCR) to configure the behavior of receiving Wi-Fi packets by calling the
wifi_config_set_rx_filter()
API. The RX filter settings indicate the desired packet format to receive, such
as broadcast, multicast and unicast frames, as shown in Table 14.
Table 14. RX filter definitions
