unsigned __pad9__ : 24
reserved
unsigned sig_len : 12
length of packet including Frame Check Sequence(FCS)
unsigned __pad10__ : 12
reserved
unsigned rx_state : 8
state of the packet. 0: no error; others: error numbers which are not public
struct wifi_promiscuous_pkt_t
Payload passed to 'buf'parameter of promiscuous mode RX callback.
Public Members
wifi_pkt_rx_ctrl_t rx_ctrl
metadata header
uint8_t payload[0]
Data or management payload. Length of payload is described by rx_ctrl.sig_len. Type of content deter-
mined by packet type argument of callback.
struct wifi_promiscuous_filter_t
Mask for filtering different packet types in promiscuous mode.
Public Members
uint32_t filter_mask
OR of one or more filter values WIFI_PROMIS_FILTER_*
struct wifi_csi_config_t
Channel state information(CSI) configuration type.
Public Members
bool lltf_en
enable to receive legacy long training field(lltf) data. Default enabled
bool htltf_en
enable to receive HT long training field(htltf) data. Default enabled
bool stbc_htltf2_en
enable to receive space time block code HT long training field(stbc-htltf2) data. Default enabled
bool ltf_merge_en
enable to generate htlft data by averaging lltf and ht_ltf data when receiving HT packet. Otherwise, use
ht_ltf data directly. Default enabled
bool channel_filter_en
enable to turn on channel filter to smooth adjacent sub-carrier. Disable it to keep independence of adjacent
sub-carrier. Default enabled
bool manu_scale
manually scale the CSI data by left shifting or automatically scale the CSI data. If set true, please set the
shift bits. false: automatically. true: manually. Default false
uint8_t shift
manually left shift bits of the scale of the CSI data. The range of the left shift bits is 0~15
struct wifi_csi_info_t
CSI data type.
