"Pulse Oximeter version mismatch Update software" Error even after updating

5719831 over 2 years ago

I'm getting the "Pulse oximeter version mismatch Update software" error and my FR945 is not tracking pulse. The pulse oximeter is not blinking on the back either. I've updated to 8.20 via Garmin Express / USB to my laptop and by navigating to the Update menu via the watch controls directly. It says "Update available" on the watch, but when I click it to apply it says "SNS", then I hit the down arrow (only option I have), then it says "Updating", then very quickly goes into a reboot. When the watch is done booting back up it's at the same place - still the version mismatch error and update available on the watch. On the laptop, via Express / USB, it says I'm all up to date.

Am I missing something?

Found this in the Vivo3 forums. Looks like a bad update from Garmin - exact same issues they are seeing. Garmin-Kevin is there a fix for the FR945?

Hello. Have you managed to solve this problem? I have exactly the same. Unfortunately, the watch is out of warranty :(

Garmin replaced it. It was likely a bad firmware update that bricked the sensor. Mine was out of warranty as well - call / email Garmin support, they were great to work with.

Thanks for the answer. I called Garmin, sent a service request, and despite the fact that at first everything indicated that it was a software problem and it could be easily solved. In the end, I was only offered a discount on a new watch, with no resolution to the problem.

Steps:
1 - Turned off the watch
2 - Pressed simultaneously "light" and "down" buttons.
3 - After a few seconds a black screen with all settings it will display
4 - Press "UP" button until find a screen with a QR Code. There you will find the option "WHR" and here we will find the problem. It is turned off.
5 - Press "Down" button to turn on the option. You will see that the HR sensor lights will shine again!
6 - Exit the black screen mode
7 - Turn on the watch.
8 - Enjoy

Hope this works for you too.
Best!

Hi.

Unfortunately in 945 it doesn't work. I can't enter the settings mode you write about in step 3. Turning off and then simultaneously pressing "light" and down" does not activate this setting mode.

Thank you so much. This worked on my Garmin 245 music that was exhibiting this issue.

Glad to help

Sorry it didn't help you. It must have another way to go to this settings mode.

try turning it off and then hold the down button first and then the light button, (both together, just press down first) i kept accidentally turning it back on
