ESP32 BLE Arduino change MAC after initialization
Posted: Mon Feb 14, 2022 11:28 am
Hi,
I am using the ESP32 BLE Arduino -> BLE_IBeacon example in Arduino IDE and would like to be able to change the MAC-Address of the advertising device after I initialized the BLEDevice.
Right now it looks like this:
This changes the BLE-MAC-Address before initializing the BLEDevice. After the initialization
does not work anymore and the advertised mac stays the same. The only way I found to change it was to use
but this erases everything.
I know it is possible, because
https://docs.espressif.com/projects/esp ... m-base-mac
says "It is also possible to call the function esp_netif_set_mac() to set the specific MAC used by a network interface, after network initialization.", but I can't make it work.
I tried including the necessary libraries and using esp_netif_set_mac(), but I don't know how to get the esp_netif Parameter.
Can someone help me or show me a working example please?
