• if I do the following:

    • set GPIO0 pin to GND on the ESP01 board
    • clicked the firmware update button (firmware downloads)
    • when the IDE reports: syncing.., I ground the ESP01 reset pin, then the IDE reports writing block x / 1024 (where x increments)
    • blue LED flashed on ESP01 while the block value increments
    • when it gets to 512, the process bombs out with the following IDE message:

    The Firmware update failed: Unexpected response {"dir":1,"cmd":3,"len":2,"data":"\u0001\­b"}

    @Gordon, what do you think?
