I have been donated an older Spark Core v1.
When connecting it to my PC, I get a cyan breathing for 1 second, then solid blue for 1 second… flashing blue light…maybe twice a second.
My PC sees no USB device.
I’ve installed the Spark drivers.
I’ve tried to hold down Reset + Mode… then release reset… holding the mode button down…device resets… but just returns to the blue flashing LED…
Has the device maybe given up on life?
