Updated to 19.21 - Broke power meter connection

Hi Blake,

I tried using another bike I have with the same type of crank and it wasn't dropping the connection. So it very well may be a combination of the software update and the crank itself.

Is it possible the battery is low on the crank having the issue? Signal might be weaker, if the battery voltage is sagging a bit, and that combined with the problem Luko is describing might have caused it to to start dropping.

The battery appears to be okay. It isn't fully charged but more than 75% charged. I just recharged it on the weekend.

I will give that a try nevertheless. 

smithfx Please look out for an email from me today requesting some information we wouldn't ask you to send through the forums. We will look into this with you, but my immediate assumption is that there is something that will need to be looked at with the power meter itself. 

This isn't passing the blame, it's just that there were no changes in the 19.21 that would impact the Edge communicating with your sensors, of any kind. 

I appreciate your willingness to correspond further, and thank you for your patience. 

when you search for a power sensor , it should find it under 2 names, one of it the ANT+, the other is the BT (if you go into the sensor details, it should show the used protocol. Then if found it on both, your should disabled the ANT+ version, and in this case the Edge will communicate via BT with your powermeter. it is the same with dual-hrm heart belt also, for example the Polar H9/H10 has much better signal (less artifact) via BT for HRV measurement during training, so i use that one and the ANT+ version is disabled. (disabled and not deleted, it is true for power sensor also, because if the auto -search is enabled, the Edge always find all ANT+ device automatically, and will use the ANT+ instead of BT, the ANT+ has higher priority in Garmin devices as i know)

if there are differnt firmwares in the 2 Zwatt cranks, that could be a problem (small chanche but could be) . 

Blake, no problem. That was why I wanted down grade to the previous version to double check. As I mentioned in another post, I tried another crank it seems to be working fine. I really hate it when things get updated and stuff breaks because the first thing that is obvious is the update especially if it worked just a couple of days before.

no issues here with the power meters on the stages SB20 using 19.21 via ant+. ride last night went great as usual. will confirm again on next scheduled ride this coming saturday

I own a Garmin Edge 1040 Solar and I'm having same problem with U2e Power Meter (similar to Stages on Crankset).

At first, the power meter connects normally and works fine. After some riding time, it starts disconnecting and connecting at around 30 seconds. Missing several readings and not providing correct stats.

I have other sensors connected to my Edge device, such as speed sensor (Bontrager Duotrap S), Lights and Radar (Garmin Varia UT800, Garmin Varia RTL510), and broadcasted heart rate (Garmin Fenix 5S) - all of them work fine, except the power meter.

– Updated firmware to version 19.22 but issue still occurs.

Power meter connection was fine at some previous firmware versions

Hi! Did you fixed the issue? I'm having the same problem with the thm clavícula power meter
