My Spark Core has been working for weeks. Now I cannot get it to connect.
When I power it on it starts blinking green, then it goes to breathing cyan for about two pulses, then it goes back to flashing green.
I could not find this specific blink sequence on the forums.
I have tried going back to factory settings, several times, and using Tinker to give it WiFi credentials again. This often, but not always, works (Tinker asks me to name the core). After Tinker asks me to name the core the core continues to flash green.
I have done a
spark flash --usb cc33000
it ended with this
File downloaded successfully Transitioning to dfuMANIFEST state Error during download get_status Flashed!
I tried rebooting my WiFi router; that made no difference.
I don’t think it’s my WiFi router model, since the Spark has been working here for the last month or two.
What advice can you give me?
