Heartrate monitor stops working #117

Closed grriffin closed 9 years ago

grriffin commented 9 years ago

I got one of the Under Armour 39 heart rate monitors during that sale last month, and tried using it for the first time today. It seemed to record my hear rate for about 100 meters, then it flat lines at about 155 bpm. No change in heart rate after that. When I stopped the activity, on the basic start page, it showed my heart rate as 172 so clearly it was above 155.

Is this normal for these heart rate monitors? Do they lose connection and the app will assume the heart rate is the same as the last that it read for the rest of the activity? I just don't know how to tell if this is my heart rate monitor, my phone's bluetooth, or the app...

Hi,

1) what kind of HRM is this, is it a BLE one ? 2) what android version/phone do you have ? 3) there is an open bug about HRM not reconnecting if it loses connection during a workout.

I have a Polar H7 HRM (BLE) with a samsung s4 mini (android 4.2). It works flawlessly 98% of the time...but once a year or so, I also lose connectivity.

My plan for the open bug is to make the reconnect functionality so that it works for all different kind of HRMs

1) Under Armour 39 BLE heart rate monitor. 2) Samsung Note 2 with Android 4.4.2 3) OK I saw that issue, but wasn't sure if that was what happened. What makes it lose connection? Bluetooth seems pretty stable for car audio...but my fitbit does possibly interfere. Maybe I should run without it. I don't have it background syncing or anything, but about half the time I go into the fitbit app it tells me that it has to restart bluetooth before it can sync. Maybe my phone has terrible bluetooth.

btw, this looks like a duplicate of #104 wdyt ?

Yes this can be closed. BTW, I noticed in the other issue you mentioned that the S3 was flaky in regards to bluetooth. The Note 2 is very similar to the S3. Likely it has the same problem. I'm about due for a new phone anyway. So..sure, I can upgrade my phone just so I can use a heart rate monitor. Justified don't you think? ;)
