MAC addresses

[Jan Kijonka]

Hello,

are the MAC adresses for Station and softAP different for each ESP-12E device ? If I produce for example 10 000 devices with the ESP-12E, should I make some collection of MAC adresses for my production and give to each of the device unique MAC adresses (AT+CIPSTAMAC, AT+CIPAPMAC) ? I need to ensure identification for each ot these devices, because there can be up to 50 devices connected to one IP address at the same time in my application.

Hi,

Yes, MAC address is unique, MAC addresses for Station and softAP are different for each ESP-12E device.

Thanks for your interest in ESP8266!

Thank you,

the MAC addresses stay unchanged after flashing new firmware (I have Not yet tested) ? I use ESPFlashDownloadTool_v3.4.8 and NON OS SDK v2.1.0.
