So, if you use the BLK3 mac address it simple doest work, blufi or wifi simple sta / sta/ap connection.

Mac from efuse BLK3 code from the esp-idf example:
uint8_t mac_addr[8] = {0};
esp_err_t ret = ESP_OK;

Wifi simple doesnt work, there is a WIFI problem with BLK3 custom mac address

[negativekelvin]

You can't set the multicast/group bit so your first byte could be 0x48 but not 0x49

[projectgus]

Hi @filzek ,

@negativekelvin beat me to answering by 3 minutes, it seems. :)

The esp_base_mac_addr_set function should fail in this case (invalid MAC) with an error, we'll fix this.

Angus

[filzek]

Okay, the efuse has a valid mac address, and the code seems valid to run, but wifi simple doesn't work.

@projectgus and @negativekelvin so the problem is with the wifi interface?

[projectgus]

@filzek The MAC 49:4f:54:00:01:31 is a multicast MAC address. So it's not a valid unicast MAC address. This is why it doesn't work, the Wi-Fi library is trying to use it but the AP is correctly rejecting it.

To make it into a unicast MAC then you need to clear bit 1, changing it to 48:xx:xx:xx:xx:xx

BTW, because 49:4f:54 isn't a valid OUI then to "do the right thing" you should also set bit 2 indicating it's a "locally administered" MAC, which would make it 4a:xx:xx:xx:xx:xx.

If you have already saved this MAC in efuse then you can change it in code after you read it but before you call esp_base_mac_addr_set:

base_mac_addr[0] &= ~0x01; // make unicast
base_mac_addr[0] |= 0x02; // mark as locally administered
esp_base_mac_addr_set(base_mac_addr);

[filzek]

Sure, I have no Idea why we didn't see it before, the lab testing was mean to be 49:4f:54 to hex to text IOT, but we forgot about multicast address.

Anyway, we found one brick in the wall, so, let's fix multicast address in interfaces setup.
