Hi, I was wondering if anyone could help me, I was working on my program and the after some modifications, the core flashed red (overload I guess). I did a factory reset to clear the bug and to upload a new version of my program, but the core won’t connect to Wi-fi (keep flashing green). I did more factory reset, but still nothing. I try an other wif-fi and uploading credential from my computer.
I also try to upgrade the firmware (https://community.spark.io/t/tutorial-upgrading-factory-reset-firmware/3430), but I was getting this error:
Filter on vendor = 0x1d50 product = 0x607f
Opening DFU capable USB device… Cannot open device
This happen with both of my Core, but not with the same program.
I’m running out of idea…
