  1. The following MAC addresses are derived from the BASE MAC in the EFUSE BLK0. #ESP_MAC_WIFI_STA #ESP_MAC_WIFI_SOFTAP #ESP_MAC_BT #ESP_MAC_ETH For 2 universal MAC addresses, the BT and Wifi are both enabled. Ethernet is disabled. Here: #ESP_MAC_WIFI_STA=ESP_MAC_WIFI_SOFTAP=BASE MAC
  2. Figure 1 - MAC addresses of the stations connected to the ESP32 soft AP. You can then compare the printed MAC address with the MAC address of your device to confirm they match. In my case, one of my devices is a Windows machine. So, if I send the following command in the command line, I will get its MAC address
  3. We have now added a new static method called BLEDevice::getAddress (). While coded, it has not yet been tested other than to validate a clean compile. When called after a BLEDevice::init (), it should return the BLE address of the ESP32. To the best of my knowledge, the BDA is hard-coded

In this example, I just want to know the MAC address only, without connect to any hotspot, so no ssid and password needed.http://arduino-er.blogspot.com/2017.. Here is how you set a custom MAC address on ESP32 with examples. I recently struggled getting two ESP32's to talk via wifi-now. My main problem was that I wanted to set custom mac addresses for the units. ALL (100%) of the examples I found were for the 8266 After uploading the code to your board, open the Arduino IDE Serial Monitor at the baud rate 115200, restart your ESP32 board and the IP address defined earlier should be assigned to your board. As you can see, it prints the IP address 192.168.1.184 To fetch MAC address for a specific interface (e.g. Wi-Fi, Bluetooth, Ethernet), you can simply use esp_read_mac () function. By default, this function takes the eFuse value burned at a pre-defined block (e.g. BLK0 for ESP32, BLK1 for ESP32-S2) as the base MAC address. Per-interface MAC addresses will be calculated according to the table above

The problem I am facing is that due to the recent changes in the Operating System of Android and Apple, the smartphones would use Randomised Mac Addresses to probe for Access Points. As the ESP32 detects different probe requests, the counter continues to increase. I was wondering how to fix it; thus, I came here for some answers To get the MAC dress of the ESP8266, we simply call the macAdress method on the WiFi global variable, which will return the MAC address in the hexadecimal format mentioned early. You can check the full working code bellow, which also includes the empty loop function
