OK. Good to know about the BLE and it being available for other devices. I CAN connect my P2 to upTempo to register HR. Sadly this doesn't work as you would wish/hope it would. The app sees my P2 in the list of devices and when I go to setting and turn "Connected to saved BLE devices" to On. I get these steps in the settings of my P2:
When finished with the activity (and because of batterylife) I select Stop Sharing on the P2. The P2 again shows "Now Discoverable" in the Bluetooth menu. When at a later point I once again go to Start Activity -> Settings, the watch doesn't reconnect or asks to "Share heart rate". When I disconnect the BT and reconnect I do get this option again. But I think that's a Pebble (P2) issue, the same thing happens in Runkeeper.
I did notice upTempo also records my HR when I start the Workout watchapp on my P2! That app probably activates the BLE of the P2.
And when connected it does show the info I need!
I do notice it sometimes automaticly records an activity when I for example drive my car (about 20km/hour) looking for a parking lot. The Pebble Health app doesn't show this. Maybe because upTempo is more about Runs and Pebble is about Steps?
This one is kind of weird. I woke up at 7.00, got dressed etc and at 7.30 started a manual Activity on the P2 for my bikeride to work. Somehow the app registerd this activity within the Sleep of that day, with that timezone being Awake. And no seperate activity for my bikeride.
To bad the Pebble gives notifications when the walk or run isn't yet finished. The only thing I had at night (as it shows the sleeping overview), I had to go out of bed to go to my son for less then one minute, but the app divided it into two parts with a 15 minute break in between .
I would love if it would be possible to just use my watch during an activity (outdoor run) with the Heartrate (e.g. via the P2 Workout app) but without my phone. Then when back at home and reconnected to my phone it automaticly uploads the activity to the upTempo app with the details and the heartrate (as in the second screenshot above). So I can take only the P2 with me on a run, but still have the detailed overview in the app. Do you think thats possible?
As said before. I think it's great what the app can do and plan to use it to monitor my activities!
