But on the latest environment it is not possible provide the license anymore.

Use: / The true ESP32 chip ID is essentially its MAC address./

uint64_t chipId = 0;

void setup() { Serial.begin(115200); }

void loop() { chipId=ESP.getEfuseMac(); Serial.printf("ESP32 Chip model = %s Rev %d\n", ESP.getChipModel(), ESP.getChipRevision()); Serial.printf("This chip has %d cores\n", ESP.getChipCores()); Serial.printf("ESP32ChipID=%04X",(uint16_t)(chipId>>32));//print High 2bytes Serial.printf("%08X\r\n",(uint32_t)chipId);//print Low 4bytes. delay(3000); }
