EFuse mu ESP32-S2 yawotchedwa 48-bit mac_address. Maadiresi enieni omwe chip amagwiritsa ntchito pa station ndi AP modes amafanana ndi mac_address motere:
- Njira yapasiteshoni: mac_address
- AP mode: mac_adilesi + 1
- Pali midadada isanu ndi iwiri mu eFuse kuti ogwiritsa ntchito azigwiritsa ntchito. Chida chilichonse chimakhala ndi kukula kwa 256 bits ndipo chili ndi chowongolera chodziyimira pawokha cholembera / kuwerenga. Zisanu ndi chimodzi za izo zitha kugwiritsidwa ntchito kusunga makiyi obisidwa kapena deta ya ogwiritsa ntchito, ndipo yotsalayo imangogwiritsidwa ntchito kusunga deta ya ogwiritsa ntchito.
