Before today, my core was working just fine. Had some downtime at the office, so I played around writing a few simple cloud-controlled functions, everything was fine. It had previously worked well at my home network as well.
Now, though, I cannot get the Core to connect. I’ve gone as far as factory-resetting it; manually programming the wireless credentials just left it blinking green endlessly.
After using the Android app, it accepts my credentials, and begins flashing fuchsia as it does when it is being reprogrammed, then begins attempting to reconnect. It briefly flashes green, then rapidly flashes cyan for a moment, before sitting on a solid fuchsia light for a few seconds before repeating the loop all over again. Eventually, it will either begin blinking cyan as if it’s lost the connection, or it will just sit on a solid fuchsia light, as it is currently doing. It has done this both at my office and here at home; it’s worked fine at both places before.
I’ve tried to reload the factory firmware via DFU mode, but that only results in dfu_util.exe giving me the message “Opening DFU capable USB device… Cannot open device”
How can I restore my Spare Core to working order?
