Is the phone actually connected to the powermeter? If you swipe twice to the left, to the debugging screen, what does it say for the sample rate?

hi .. my you say me why i have negative w last 30 sec rpm is positive . and what i may make to fastest change actual power on display . ? I program last version app .

                                                                                           thank ypu

@jura38 The wattage can show up as negative for a brief period whenever the left pedal arm is being lifted by pressing the right pedal arm down (so that the "kg" indicator is negative).

It's just a mathematical method to make it take both pedal arms in count even though it's a left-only power meter.

The screen updates each second and can't be changed (unless you install Android Studio and re-compile the program - this is actually pretty simple). The scroll wheel selects how many seconds to average over, for the "current wattage"

thank you I solved the problem of negative average strength. The problem was that I calibrated the powermetar in an improper manner. And the power and the average power were negative. It is clear that the weight has a positive and negative comonomer depending on the direction.

I do not have a clear label of 1-30 but now everything is clear ..

I do this for a supper by putting the gouge of life span 10 000 000 bending

hi . Have you idea to inplementation heart rate monitor in android program , and heave possibility connecting two ble device . One from powermeter an second from heart rate ble senzor ..

rrrlasse commented 5 years ago

@jura38 it should be possible to connect to two BLE devices. The heart rate protocol is described here https://developer.android.com/guide/topics/connectivity/bluetooth-le

ooo for mee android studio is nasa project ,,
