I’ve been struggling to revive an old spark core that worked fine the last time I used it several months ago. It had connected fine over my wifi to the spark cloud. And I also had it working fine on a local cloud. Now it won’t connect to anything. After trying everything I could find on line, I decided to start over and reset it back to connecting to the spark cloud. But I can’t get it to connect. My wifi has not changed and I’ve rechecked all credentials multiple times.
I have done factory resets (MODE + RST tap til flashing white), and wifi resets (MODE til rapid blue flash). I have tried iPhone app setup but get only blue flashing and “no cores found”. I have tried USB setup via linux screen to enter SSID + WPA2 + pw. It says it loads but the spark then flashes green, then cyan, then red (3 times) and repeats. I can see the <core_id> using spark identify when in listening mode. I have tried using sudo spark keys doctor core_id when in DFU mode, which seems to work except I get “submitPublicKey got error: Permission Denied” when it gets to uploading the new public keys to the cloud. I then used spark keys send <core_id> <core_id>_new.pub.pem, which says “submitting public key succeeded!”. But it just flashes blue and won’t connect.
I suspect a keys problem, or a corruption of some kind. How can I complete reset the core and start fresh? Do I need to also clear out anything on my cloud account as well?
Thanks for any help…
