ESP32 Forum

Good morning,

I am working with Esp32S3 chips.
I have implemented BLE on many firmwares and I get the BLE adresse of the chip using the method :
Err = esp_read_mac((uint8_t *)&BTMACAddr, esp_mac_type_t::ESP_MAC_BT);

I would like to know if the BT MAC Address is unique on your chips ?
Or is it possible to get two BT MAC addresses that are the same over two different chips ?

Thank you for your help,
Best regards

Another question : If an Android device (Smartphone/Tablette) see my device using BLE.

Will the BLE MAC address detected on the Android Side be the same as the physical BLE MAC address of the chip ?
