The RX callback function in the promiscuous mode. Each time a packet is received, the callback function will
be called.
Parameters
• buf: Data received. Type of data in buffer (wifi_promiscuous_pkt_t or wifi_pkt_rx_ctrl_t) indicated
by ‘type’parameter.
• type: promiscuous packet type.
typedef void (*esp_vendor_ie_cb_t)(void *ctx, wifi_vendor_ie_type_t type, const uint8_t sa[6],
const vendor_ie_data_t *vnd_ie, int rssi)
Function signature for received Vendor-Specific Information Element callback.
Parameters
• ctx: Context argument, as passed to esp_wifi_set_vendor_ie_cb() when registering callback.
• type: Information element type, based on frame type received.
• sa: Source 802.11 address.
• vnd_ie: Pointer to the vendor specific element data received.
• rssi: Received signal strength indication.
typedef void (*wifi_csi_cb_t)(void *ctx, wifi_csi_info_t *data)
The RX callback function of Channel State Information(CSI) data.
Each time a CSI data is received, the callback function will be called.
Parameters
• ctx: context argument, passed to esp_wifi_set_csi_rx_cb() when registering callback function.
