Not working Bluetooth after update to version 11.03

8814244 9 days ago

Hello. After updating to version 11.03, Bluetooth isn't working. In the device section, the Bluetooth version is now 0.00. The MAC address is also 00.00... According to the forums, this is a common issue. How can I fix this? The watch is less than two years old. Is it possible to downgrade the firmware to a more stable version? I look forward to your reply. Thank you.

How's the free space on your watch? This is usually the main cause of update issues. If it's low, delete any previously synced activities and run the update again. There are no problems with BT on 11.03…

Hello. There are no issues with free space on the watch. The update was installed on a completely reset watch.

Resetting doesn't clear the memory used by activities; free space is shown in Windows Explorer when connecting a device. I have about 17 megabytes (MB not GB) of free space.

I installed the update on a completely cleared watch. Free space is about 17 MB.

Then maybe it's worth reinstalling the update again, it seems this is done by pressing the backlight key 8 times, or you can google it.

I can't access the development menu via the backlight button to reinstall the update. Perhaps the Forerunner 55 model has a different way of accessing the development menu. I've tested this on other Forerunner 55 watches.

If your watch's Bluetooth version and MAC address are 0.00, I recommend using Garmin Express on a personal computer to ensure that the full software has pushed through. Here's how to do that:

Using Garmin Express to Update Your Watch's Software

You will be unable to revert to a previous software version.

Hello. I've tried everything you described and more. It doesn't help. Bluetooth keeps asking for an update, but the version remains at 0.00. The Bluetooth test passes successfully in the service menu. Therefore, the problem is related to firmware 11.03.
