Error while burning bootloader.

I think I successfully burned the firmware on the 1st attempt. The subsequent burns are unsuccessful.

The mDNS works. I need to load SimpleWebServerWiFi.

I am a novice. So sorry.

Have you installed the firmware successfully? You can check the firmware version of the duo by sending “v” through the serial monitor when the duo is in listening mode.
