Edge 540 dropping power meter connection after upgrading to v21.16

I am running an Assioma UNO with my Edge 540 for few months now. (I've had the UNO for a year and 540 for few months).

There were no issues until the 540 prompted to upgrade on 24th May 2024, since then I started noticing drop in connection with the UNO. And it seems like it's happening every 15-20mins or so.

I've had 2x long'ish ride since and it was happening on both rides.

Currently it's connected via BLUETOOTH

I'm still yet to try it on ANT+ - will update the post once I've tested this.

also experienced this with my Quarq PM, no issues prior to this v21.16 update, but now won't display power (or cadence) even though it "finds" the Power meter after removing it, and re-adding it. New battery, etc no effect.

There is another thread on this topic. An issue with power meter connectivity over BLE has been found. Garmin are working on a fix. In the mean time you can use ANT connectivity as a work around,

these devices were launched, what? over a year ago? and still riddled with bugs.

I feel like a constant beta tester.

I have the same problem with my inspider rotor and garmin 540 and fenix7.

How can you connect via ANT? I can only connect via bluetooth....

Same issue with SRAM transmission XX power meter, working great yesterday, no power measured after the update (removed and added sensor back in, it's connected but not displaying any data).... come on Garmin, you should be better than this. I'll try connecting via ANT+ and see if that works.

If you connect via BT perhaps this is the answer, worth a try?

Yes how do we connect via ANT+ specifically. It only picks up the power meter as a blue tooth option

Of now my fenix 5 watch has no issues with any of this

540 screwed up just after updating
