I have a nice new ForeRunner 255, that is driving me crazy. It will not stay pared with Samsung A32 phone. I've been on chats with Garmin support, and they even sent me a new watch that behaves exactly the same as the previous one. It disappears from the top of Garmin Connect, and when I go look under "Garmin Devices", the FR255 shows as "Registered to Garmin Connect" but is not paired. Then I have to go through the whole pairing procedure like it is a new device. This is a pain, and unacceptable for a brand new $500C device.
I have just discovered that turning on my Garmin Edge 530 so it connects to GC, makes the FR255 un-pair. The Edge 530 never seems to un-pair.
I had posted this previously in one of the many threads about Forerunners losing pairing with phones, and Garmin e-mailed me to start a new thread, so here it is:
"My 255 keeps disappearing from Garmin Connect, and I have to go through the whole add new device pairing routine repeatedly. Garmin support sent me a new watch, but it does the same thing. I've updated the watch, Garmin Connect, deleted and re-added all my network connections on my phone, etc, etc. Android 12, Samsung A32.
There are threads about this on other Garmin watches going back years, with huge lists of time consuming things to do, none of which are a definitive solution. My Garmin Edge 530 bike computer has always stayed connected, and my old Amazfit watch was connected to several phones for years without an issue. There is something wrong with Garmin's watch firmware.
I like Garmin Connect when it works, and it is very good to have my bike computer and running watch rolled up in the same app, but I am very tired of the disconnects and no solutions from Garmin support. I'm thinking of sending the 255 back before the 30 day free return period is over, and trying a Coros."
I have tried an awful lot of the suggestions at the top of this thread. I have also updated the 255 to the Beta software version 12.27. I thought deleting all the networks from my phone, and then building up the WiFi and Bluetooth pairing all over, worked, but now I've found just starting my Edge 530 (up to date firmware) kicks my Forerunner off Garmin Connect, and I have to again do the whole re-pairing procedure.
There are dozens of threads in these Garmin Forums about Garmin watchs un-pairing from Garmin Connect, going back years. There is obviously a fundamental issue that all their time consuming suggested "fixes" do nothing to address. The support people on their chat don't have a clue. It's like it's a new problem they've never heard of, and they have no idea of how to fix it.
