I just received my core with chip antenna. I had problem registering it via the app (on both devices - iPhone5 and Nexus5).
I managed to connect it via the usb and registered it. Now I can upload my sketches from the site and control it with the Terminal on my macbook.
BUT, still I can not connect to the spark with the app and both machines send “No Cores Found” error…
I have a 2.4ghz wifi. with password and pretty ordinary.
I checked all the previous post but I did not find any answer.
Hope some good sole could help me fix this problem.
Thank and Great work,
