Start by connecting the core to a normal network and claim it and set everything up. program it with your code you want to run on its normal network. put the core in listening mode by pushing the mode button for 3 seconds till it flashes blue, enter your wifi logon details using usb. once you have connected your core to the wifi you should be able to run in manual mode or semi auto. all you need is wifi.on and wifi.connect. if you call wifi.setcredentials it will put the core back to flashing blue waiting for wifi logon details.
pretty sure flashing green is connecting to wifi, breathing green is connected to wifi but not the cloud
I remember some new LED color patterns being introduced a while back, maybe @bko can confirm this is still the case, i cant find the full list of color patterns anywhere. I've searched the docs and support sites, but cant see anything besides the standard colors and troubleshooting colors.
