Chest heart rate monitor, data drop outs

Hello Garminers!

I have a Forerunner 245 Music which I use with a wahoo TICKR 2 heart rate monitor.

In around half of my activities, I have spots where the data goes missing for approximately 30 seconds, and then it returns.

Here are a couple examples:

Also note that the data seems to drop out every five minutes.

I initially thought that the TICKR was the problem, but I've been sent a replacement unit.

Has anyone else experienced this issue?

I experience this along with Speed sensor drop out a lot when training indoors. Recently after reading causes for ANT+ drop out, I was able to pin point it to my WIFI channel number settings. I was on 'auto'

2.4ghz wifi overlaps ANT+ freq in the higher channel numbers. So it is better to change it to manual mode and set it to 1 to 3 channel. Since I changed last week all of my sensors are 100% , zero drop out! :-)

If it is outdoor... when typically due to placement, snugness, static, dry strap/skin, etc.

Outdoor it is the „Autolap“ function, that is why it occurs every five minutes!

I had this too, with a Bluetooth HR Sensor. After every autolap, the watch lost contact for 5 to 10 seconds. There was no HR for that time in the graph, I did not have drops, though. I did not find a solution for it.

Since I also had problems to connect that BT HR sensor to my Concept2 rower, I gave the Garmin HR Dual a try and use it in ANT+ mode to connect to my FR245 and the Concept2. That works very good for me, no connection loss since then.
