I’m on MacBook Air with iPad Mini and Nexus 6… had some issues getting connected and registering, here’s how they were resolved:
Cores arrived, apps installed (on iPad and Nexus) - using the apps, managed to get ‘breathing cyan,’ but both apps kept saying ‘No Cores found’ and CoolTerm would connect but commands wouldn’t result in response - or the CoolTerm connection would be refused. Without a connection (or working app), no way to know core id’s and no way to register cores on the web IDE.
Spoke with Zach from Spark and he suggested the following fix, which worked:
Use ‘screen’ in the terminal to scan for and connect to the Core.
First, get a list of usb devices:
sudo ls /dev/tty.u*
My output was:
Then use screen to connect to that device:
sudo screen /dev/tty.usbmodemfd121
Once in, press ‘i’ for your core id or ‘w’ to enter network credentials and connect to your wireless network.
With core id in hand I was able to then go over to the web IDE (https://www.spark.io/) and register my core.
Hope that helps anyone who runs into a similar problem.
