My old phone died on me a few months back. Completely. It has been a while, but as I recall, the meter was sent in for the firmware upgrade. It had been working on the old phone. I just didn’t have much of a chance to tinker with it and really get comfortable using it. Got a new phone (iPhone X) but life has been a bit sideways and I haven’t had a chance to sit down and start really exploring the Illuminati meter with it. I’ve done all the steps above and I get no connection. The meter spins in blue and green LED light and the app says “Scanning”. This goes on until the meter turns itself off. I even tried replacing the batteries in the meter. I am currently updating to iOS 12.1.1 as I type before trying again.
