I have been using my Fenix 5 as a heart rate monitor. Never had an issue pairing with my Edge 520 Plus. A couple rides ago the HR field on the Edge froze and didn't record the HR data. On the next ride the the Edge pairs with Fenix 5 HR (it says paired in sensor settings but doesn't show sensor information). So the Fenix 5 is pairing with the Edge (broadcasting HR) but the HR field on the Edge remains blank and it doesn't record any data. So no HR data on any rides since. I've done a hard re-set of the Edge and the Fenix 5.
Anyone know how to fix this? I don't want to buy and worry about wearing a strap. Thanks.
