I ordered four
SparkParticle Cores back in February. All of my debugging, testing, etc. has been done with just one. I finally decided that it was about time to open the other three boxes, and claim the Cores. The claiming/WiFi setup was uneventful on two of them, so that makes three out of four.
The fourth one…it booted to “connecting” (instead of blue flash, “listening”)—and this is the first time I’ve powered these up, too.
Anyway, after struggling with being unable to setup WiFi credentials on this Core, I did a factory reset. This time, the credentials easily went in. BUT…it won’t connect to the ! Immediately after a factory reset (I’ve done it three times now), it goes through the connecting pattern: flash green -> flash cyan -> three red flashes -> fast-flash cyan for about 5 minutes. It then goes to breathing cyan…so I go to test Tinker (which doesn’t work), but the Core is immediately back to the fast-flash cyan for another couple of minutes. On subsequent power cycles/resets, I don’t get the three red flashes, but the problem remains the same.
Interestingly, it shows up on the Dashboard as having been connected. As I was able to claim it, some sort of link is being made, but not one that allows Tinker (or user code) to run.
I’ve tested Tinker on the other three Cores, and they work perfectly. Ping @BDub?
EDIT: I should be a little more patient, even if I get nothing else done in a day’s work. Particle Keys doctor didn’t work (actually, it can’t find the Core, errors “type undefined”, and fails—but I can DFU the Core with no problem). A CC3000 flash did the trick; I suspect that this Core somehow escaped the factory update before being shipped.
