Use C:\ncs\v2.x.x\nrf\samples\wifi\radio_test

step 1. Give following cmd to check spi communication b/w host and nRF700x
cmd 1 -> wifi_radio_ficr_prog

step 2. Use following cmd to get write access
cmd 2 -> wifi_radio_ficr_prog otp_write_params 0x100 0x50FA50FA

step 3. Use following cmd to write your own mac address
cmd 3 -> wifi_radio_ficr_prog otp_write_params 0x120 0xA1B2C3D4 0x1111

step 4. you should reset the device after given cmd 3

step 5. Use following cmd to check succesfully the mac address writtern or not
cmd 4 -> wifi_radio_ficr_prog otp_get_status

Hi, I face the same issue. Adding the exact same code at beginning of my main does not solve the issue. Any update?

Hi,

I tried this code but nothing changes. It seems that the wifi_nrf is initialised before the entry in main function and I got the <err> wifi_nrf: wifi_nrf_if_start_zep: Invalid MAC address: 00:00:00:00:00:00.

Maybe there is something to do in the prj.conf to avoid this ?

Hi Rajendran Veerakaran,

It can be achieved through net mgmt command. Please refer to the example down below.

//header for net mgmt command
#include <zephyr/net/net_if.h>
#include <zephyr/net/ethernet.h>
#include <zephyr/net/ethernet_mgmt.h>

//code example setting the MAC manually
struct net_if *iface = net_if_get_default();
struct ethernet_req_params params;
static const uint8_t my_mac_addr[6] = { 0x02, 0x80, 0xe1, 0x69,  0x80,  0xc2 };
memcpy(params.mac_address.addr, my_mac_addr, 6);

int ret = net_mgmt(NET_REQUEST_ETHERNET_SET_MAC_ADDRESS, iface, &params, sizeof(struct ethernet_req_params));
if(ret) goto out;

BR.

Hi Arvin,

Now I am working with nRF9160 + nRF7000. I am facing the same problem. may I know function how did you change MAC address in run time. Thanks in advance.

Hi Kenneth,

Thanks for your help. The problem mentioned above seems to result from HW's power sequence. Now wifi stack can scan and discover APs nearby.

Many thanks

Hi Keeneth,

It's a customized board, in other words, the onboard nrf7002 is brand new. I had referred to the nrf7002DK's dts pin setting making it almost the same, including the bias (pull-up or pull-down), and still don't show any AP's SSID after the scan command.

Many thanks
Arvin

Can you tell me details about the nRF7002-DK you are using? Which version it is for instance.

Hi Kenneth,

Thanks for your reply. Wi-Fi stack starts to run successfully after I set the MAC manually. So I had tried to use sample's shell command wifi scan to check the APs nearby but the result is contrary to the actual deployment, at mean time, there are no error message.

I have no idea what this kinds of situation result from. If it means nrf7002's pin setting is incorrect？

Hi,

You can use the alternative method mentioned in the documentation like this.

struct net_if *iface;
struct ethernet_req_params params;

...

ret = net_mgmt(NET_REQUEST_ETHERNET_SET_MAC_ADDRESS, iface, &params, sizeof(struct ethernet_req_params));

The MAC address need to be given to params.mac_address.addr. It can be provided directly in the code, for example:

static const uint8_t my_mac_addr[6] = { 0x01, 0x02, 0x03, 0x04,  0x05,  0x07 };
memcpy(params.mac_address.addr, my_mac_addr, 6);
