I bought 2 Spark Core back as a Kickstarter. Haven’t had time to test them until now. We’ll first Core was a work just as quick start guide described. No problems at all. The second one I have still not been able to connect to either the iPhone tinker or to the cloud by specifying wifi credentials by USB. Have even tried to give wifi credentials via the TI WiFi Smartconfig app.
I have updated the firmware from various instructions I have found. This being the last https://community.spark.io/t/tutorial-upgrading-factory-reset-firmware/3430
In the best runs I get a blue flashing to go to a green (even with the iPhone app) but then I get flashing red. Every single time! starting to give up soon. Via the USB I got the device ID but that can’t be claimed.
At the moment this is all I get https://www.youtube.com/watch?v=VNPwiqs0jlU
Latest test was to use an alternative wifi router.
So, what is the secret to just get it to connect?
