I have been using this app on my Fenix 3 since the app came out. I introduced to all my sailing friends and they all use it. Please add Forerunner 55 as compatible device. It has the same screen resolution as the Fenix 3 and there should be no compatible issue.
This code means the device Bluetooth isn’t working/available , can sometimes be solved by closing and opening the connect/IQ apps, and checking the connect/IQ app permissions in your phone to ensure Bluetooth is allowed and connected
the watch doesn’t have an internet connection and uses Bluetooth to download the files using your phone’s internet connection
