How to change wifi, Bluetooth MAC address #317

Open xmlhp opened 8 months ago

xmlhp commented 8 months ago

We need to use the MAC address we bought. How to change the address? How to permanently save the address to esp32c3?

mantriyogesh commented 8 months ago

Please check https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/misc_system_api.html

This was changed in the firmware. How do I change through the driver on linux？

I can't config the hwadder by ifconfig espsta0 hw ether xx:xx:xx:xx:xx

mantriyogesh commented 8 months ago

For Wi-Fi, the call is available, wifi_set_mac().

test_set_mac_addr() can also be used, as it calls 'wifi_set_mac()' internally.

But this clearly needs to be agnostic and need to support Bluetooth. For bluetooth, yet not available, but little change you can re-use this API for bluetooth also.

mantriyogesh commented 8 months ago

Make sure that the espsta0 mac address if for the 'STA' interface MAC address at ESP. Otherwise you will face issues in delivering packets correctly.

Make sure that the espsta0 mac address if for the 'STA' interface MAC address at ESP. I don't understand. What does that mean.

I am sorry, this is not applicable for NG. Let me check for NG.

Right, https://github.com/espressif/esp-hosted/blob/26f4fa56bb2dd8504cc24efefa03a4e5ffcd0535/esp_hosted_ng/host/main.c#L349

esp_set_mac_address should be automatically used, when you set mac address on interface espsta0. So the thing, you had tried, should have worked.

  1. Can you please share ESP log

  2. Which git commit do you use and what is the host git commit?

    There is also restriction of MAC address . It is JFYI, you are not using such mac address anyway:

Then, how set the mac for bluetooth?

mantriyogesh commented 8 months ago

For Bluetooth yet not supported, need to add this support.
