Forerunner 245 Heart Rate Sensor only works after soft rest.

Last week I notice that the body battery was off, then went to the gym and the heart rate reading was way too low (90s insteadon 130s+).

I followed the suggestion on this forum and did the soft restart. The body battery started to show a reasonable number and the HR during a run seemed reasonable. 

After 5 days, it happened again.. I did the soft restart and it's working now.

Is there a more permanent fix? It seems like a software issue, would be great if I don't have to buy a new one.

If I don't realize there is an issue before starting a workout, the HR reading is useless. Which is very annoying. Alternatively, I have to do the restart every time I use it. Also annoying.

  • Something like this has been happening to me. It only seems to be while cross country skiing though. Gets stuck between 90-100. With swift tonight it stopped completely after twenty minutes but I think that may be more of an issue with the virtual run activity

    I'm going to try a power down, see what happens
