Type Definitions
typedef void (*wifi_promiscuous_cb_t)(void *buf,
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
by 'type'parameter.
• type: promiscuous packet type.
typedef void (*esp_vendor_ie_cb_t)(void *ctx,
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,
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.
• data: CSI data received. The memory that it points to will be deallocated after callback function
returns.
