I can't seem to update the firmware. I'm following the instructions to the letter. I even installed the WinUSB drive with the Zadig app (and rebooted for good measure). I reset the module, go to that page, select the firmware file, and the 'Program' button always remains greyed out (see photo).
[ EDIT: One thing I should add: I click Connect, then I see "DFU in FS mode - Paired." I click 'connect' in that little pop-up window, and there's no indication that it actually connected. I can then re-click the yellow "Connect" button and repeat the same exact thing. ]
Windows 10 / Chrome 97.0.4692.71
I disabled all security features of the browser for "electro-smith.github.io"
I plugged the USB cable directly into one of the ports on the PC (rather than through a hub)
Any suggestions? Thanks!
After an hour of persistence, I finally got the firmware to load.
In my case, I wonder if the micro-USB connector on the unit was a little wonky, because it took me two different cables and trying multiple USB ports on my Mac (on the Mini and a powered hub) to get it connected.
I realized that when you see the red LED light up, keep it in that position! The LED on mine flashed red so I thought that meant it was connected. Nope. It needs to be solid red. Once I was able to wiggle the cable into place so the LED was a solid red, everything else fell into place.
Hope this helps someone out there!
Cheers
