I had my Opta Wifi connected to the network and running and wanted to perform a simply update to the sketch. It looked like I could simply upload the sketch to the Opta using the existing cloud connection (via https://app.arduino.cc) and the process made it all the way to flashing the sketch but it must have disconnected the Opta from the cloud so the device is offline now and I do not believe the sketch upload completed. I will have to try to restore the device using the USB cable. Could someone look into this to confirm that sketches can be updated via an existing Wifi connection and not the USB cable?
