Any one else having lots of drop outs?

The Forerunners are also all set to have Cycling Dynamics on as well as TE/PS, so the Edge would also need to match that. The Edge units by default to having Cycling Dynamics on and TE/PS off.

Thanks, I fixed up my reply wrt the CD setting.

Hello, I use Polar M460, it has no cycling dynamics etc. but the problem still exists. I wrote to Garmin and the bike shop about the complaint. both offered me to return the pedals. I have now done this at the bike shop because I only have the pedals for 2 months. wait and see what happens.

Hello, got a new Replacement Pair today from Garmin. They had the same Problem. every 3:10 Min drop out for 1 sec.

 . . . Same here.  I am on the third set which I believe were reconditioned and they are by far the worst.  not quite as bad when installed on my Trek MTB, but still more that a several drops to zero with rides on a complete climb route - no coasting.  I certainly expect variations, drop drops to zero for up to more than 10 seconds Zooming in on the power/cadence drops reveals that the cycling dynamics are ALL dropping off at the same time as power.  Not a lot of troubleshooting or help outside of replacement. Here is an example:

Would really like to get to the bottom of this.  A bit tired of the no answers emails - just " will let the team know" when I send info

Another Theorie, because i got a new Pair Rally of guarantee from my dealer, which hat the same behavior. Powermeter pedals are high-precision measuring instruments which are connected to devices via bluetooth. how often does a cell phone lose GPS, data or Bluetooth? Every now and then my watch loses the signal to the chest strap or loses GPS signal. I don't think it's the pedals, it's the equipment. who knows what some cheap BT or Ant+ modules are built into.

So I ask myself whether these failures affect my training? No, actually not.

Having no issues with Edge1030+ and Zwift, both connected via ANT+. My theory is that BLE is not implemented correctly on Rally or the whole BLE protocol is just unreliable junk.

Usually, when you have dropouts that are exactly the same time (or multiples of that time) apart, the problem has to do with a second device whose operation is periodically wiping out the power meter's transmissions. In your case, the dropouts appear to be happening exactly 60 seconds apart for an extended period of time, which is not a common occurrence.

Are you using BLE or ANT+? The pedals will support up to two BLE devices connected to your pedals, in addition to its ANT+ broadcast. The ANT+ broadcast can support any number of listeners, but as I cautioned in an earlier post in this thread, it is important to ensure that all your listening devices have the same settings expectations with respect to the pedals, otherwise they will send conflicting commands to the pedals. These conflicting commands can also cause behaviour similar to what you are seeing.

If you are using multiple devices, then the first thing to try is to un-pair all but one of your listening devices and see if the problem persists. This includes un-pairing your pedals from Garmin Connect Mobile on your phone if you happen to have that set up.

I notice the speed data in DarrylZ4's activity also has dropouts, and they're at different times from the cadence and power dropouts. That's a bit worrying because speed is one of the most basic sensors to "get right". It may be completely unrelated, but it makes me wonder if there's an issue with the head unit (Edge 830) itself, or at least the sensor connections to it in general. I note the heartrate doesn't appear to have dropouts. Maybe it's an issue with the connection method (BT/BLE vs ANT+), reception, interference, competing connections, etc., like @t_smit suggested.
