I have read all the FMs and tried BlinkUp on my new (Delivered 21-Sep-2017) impExplorer Developer Kits. I am using an iPhone SE with the latest ElectricIMP software. I get blinking Red lights and then the Imp goes dark. Not connecting to my Wifi device (correct wifi network name, check, correct password, check). I have even done Blink up in the Dark, removed my screen protector, etc. etc. etc I have searched the forums, followed a broken link to a windows BlinkUp-App, and on, and on. Anyway just going through that so you know that I have really been bashing at this from a few different angles before posting.
