Don’t know if you got this fixed or not. I ran into the same issue. Kept kicking me out of the update. Weird thing happened today. Fought with the update for about an hour last night…zip zilch. Sit down at the front room this afternoon and it loads right up. My guess is that it gets twisted with the Bluetooth and the WiFi. Try it outside of Bluetooth range and see if it finishes the update
I dug out my older iPhone X yesterday morning and installed the Pit Boss app. I connected to the smoker and got the smoker connected to Wi-Fi and gave it another shot doing it by-the-book method.... I can’t explain why it worked this time.
I was the same distance from my Wi-Fi router. I used the same version of the app I connected to the same Wi-Fi SSID. the only difference was the iPhone X instead of the iPhone 14 Pro. I tried this before with an even older iPhone 6 that I had laying around and I didn’t have any luck.
I had previously tried all combinations. Here are a few to give you an idea of what I was doing:
Phone connected to WIFI, grill connected via bluetooth and WIFI: Fail
Phone connected to WIFI, grill connected via bluetooth only (no WIFI): Fail
Phone connected to cellular only, grill connected via bluetooth and WIFI: Fail
Phone connected to cellular only, grill connected via bluetooth only (no WIFI): Fail
....so on and so forth.
All that said, today is the victory lap, I have 2 racks of the ribs in the Elite 6 for me and my bride.
