Function Documentation

nrf70_off_raw_tx_conf_update()

int nrf70_off_raw_tx_conf_update

(

struct nrf_wifi_off_raw_tx_conf *

conf

)

#include <zephyr/drivers/wifi/nrf_wifi/off_raw_tx/off_raw_tx_api.h>

Update the configured offloaded raw TX parameters.

Parameters

conf	Configuration parameters to be updated for the offloaded raw TX operation.

This function is used to update configured parameters for offloaded raw TX operation. This function should be used to when the parameters need to be updated during an ongoing raw TX operation without having to stop it.

Return values

0	If the operation was successful.
-1	If the operation failed.

nrf70_off_raw_tx_deinit()

void nrf70_off_raw_tx_deinit

(

void

)

#include <zephyr/drivers/wifi/nrf_wifi/off_raw_tx/off_raw_tx_api.h>

Initialize the nRF70 for operating in the offloaded raw TX mode.

This function is deinitializes the nRF70 device.

nrf70_off_raw_tx_init()

int nrf70_off_raw_tx_init	(	uint8_t *	mac_addr,
		unsigned char *	country_code )

#include <zephyr/drivers/wifi/nrf_wifi/off_raw_tx/off_raw_tx_api.h>

Initialize the nRF70 for operating in the offloaded raw TX mode.

Parameters

mac_addr	MAC address to be used for the nRF70 device.
country_code	Country code to be set for regularity domain.

This function is initializes the nRF70 device for offloaded raw TX mode by:

• Powering it up,
• Downloading a firmware patch (if any).
• Initializing the firmware to accept further commands

The mac_addr parameter is used to set the MAC address of the nRF70 device. This address can be used to override the MAC addresses programmed in the OTP and the value configured (if any) in CONFIG_WIFI_FIXED_MAC_ADDRESS. The priority order in which the MAC address values for the nRF70 device are used is:

• If mac_addr is provided, the MAC address is set to the value provided.
• If CONFIG_WIFI_FIXED_MAC_ADDRESS is enabled, the MAC address uses the Kconfig value.
• If none of the above are provided, the MAC address is set to the value programmed in the OTP.

Return values

0	If the operation was successful.
-1	If the operation failed.

nrf70_off_raw_tx_mac_addr_get()

int nrf70_off_raw_tx_mac_addr_get

(

uint8_t *

Get the MAC address of the nRF70 device.

Parameters

mac_addr

Buffer to store the MAC address.

This function is used to get the MAC address of the nRF70 device. The MAC address is stored in the buffer pointed by mac_addr. The MAC address is expected to be a 6 byte value.

Return values

0	If the operation was successful.
-1	If the operation failed.

nrf70_off_raw_tx_start()

int nrf70_off_raw_tx_start

)

#include <zephyr/drivers/wifi/nrf_wifi/off_raw_tx/off_raw_tx_api.h>

Start the offloaded raw TX.

Parameters

conf	Configuration parameters necessary for the offloaded raw TX operation.

This function is used to start offloaded raw TX operation. When this function is invoked the nRF70 device will start transmitting frames as per the configuration specified by conf.

Return values

0	If the operation was successful.
-1	If the operation failed.

nrf70_off_raw_tx_stats()

int nrf70_off_raw_tx_stats

(

struct nrf_wifi_off_raw_tx_stats *

off_raw_tx_stats

)

Get statistics of the offloaded raw TX.

Parameters

off_raw_tx_stats

Statistics of the offloaded raw TX operation.

This function is used to get statistics of offloaded raw TX operation. When this function is invoked the nRF70 device will show statistics.

Return values

0	If the operation was successful.
-1	If the operation failed.

nrf70_off_raw_tx_stop()

int nrf70_off_raw_tx_stop

(

void

)
