OTA update failed - Invalid Header

#1

Hi everyone, I followed the doc about mDash and I’m trying to update my wemos d1 mini through OTA. I followed this steps:

  • Exported binary from Arduino IDE (Blink.ino.d1_mini.bin)
  • on mDash I clicked the download icon
  • I navigated to the file.bin and selected it

Anyway I get this error -1 (Malformed archive (invalid header)
