OK, I've decided to start documenting the nuances of using the NRC app(s) on the Apple Watch while using a BT HR monitor. I've been having inconsistent issues with this set-up, so I'm going to systematically try different configurations to see what works. The first trial was this morning where I could get a good 2+ mile run in. 18NOV2016 (745AM) Equipment - Nike+ apple watch (watchOS 3.1); iPhone 6 (iOS 10.0.2); Polar H7 BT HR monitor (Firmware 1.4.0, Software H7 3.1.0) I started off by connecting my HR monitor to my AppleWatch. I confirmed that the HR monitor was being used instead of the watch's built in sensor. Started the run with my watch. iPhone was in my pocket and I confirmed that it was providing the data (the blue bar showed up at the top of the iphone display). Observation #1 - the watch did not show the HR, but the iPhone did. Observation #2 - auto pause worked perfectly. I manually pressed the resume button, but I'm not sure I really needed to. When I finished the run, I started a workout on the apple watch workout app (outdoor walk). The HR data was still being provided by the BT HR monitor. Observation #3 - after the run sync'd to the Nike servers, the iPhone NRC app did not show HR or elevation data. I expected not to see the elevation since I started the run on the watch, but I figured that since the iPhone was showing HR data during the run, that it would show up. Observation #4 - I confirmed that the AppleWatch did transfer the HR data over to the phone by looking at the Health app data. Observation #5 - this one is interesting. Even though the NRC app did not record/sync the HR data, when I look at the run in the Activity app, the average HR is recorded (no min/max shown). Observation #6 - I checked the run on the Nike website and also on SmashRun, neither HR nor elevation was recorded. Observation #7 - GPS data was recorded and sync'd fine. No issues. Next run - on my next outdoor run, I'm going to connect the Polar HR monitor to my iPhone instead. I'll still start the run with the watch. My expectation is that HR will be recorded by the NRC app via the iPhone. I'm hoping the NRC app on the watch will display the HR using the watch's sensor. Future run - at some point, i'll try a run with the HR monitor connected to the watch and I'll leave the phone at home. I'll add some screenshots when I get a chance.
