I am having this problem as well. I went to set up the Spark Core with the Android app (on my Galaxy S4), and it took a long time while the button was red. Eventually it reported that no Spark Core could be found, and an additional (os-level) dialogue opened up saying that Spark could not be conctacted and to check my internet connection.
Meanwhile, the Core itself went from slow blue blinking to quick green blinking, back to slow blue, and then quick green again, and then after a while it went to slow cyan breathing. From what I’ve read, that means it’s connected. Indeed, I can see the core in my router’s web interface and I can even ping it just fine.
I’ve gone through the setup process with the smartphone app several times, having reset the chip’s memory via the instructions and rebooted (I did not try resetting the firmware to factory settings).
I went ahead and grabbed the serial number off the core via serial/USB and plugged it into the web interface to claim it. I’m bummed, though, because I can’t use the Tinker app on my phone… it looks so cool!
Here are some specs:
- Core with chip antenna, CC3000
- Android 4.2.2 / Galaxy S4
- Netgear WNR2000v2, running DD-WRTv2 with WEP2 security
I’d love to know I did something boneheaded, or I’m glad to offer any assistance with debugging.
