ANT Forum

Just got back to "refreshing" my app CycleBike+ (https://www.thisisant.com/directory/cyclebike-plus/) or (http://www.cyclebikeapp.com/) after some months away and now see this issue in this Forum about ANT+ sensors dropping when blue tooth connecting. Phone is Sony Xperia Xperia Z1 compact D5503 running Android 5.1.1. My app continuously tries to connect to paired ANT+ sensors, but they are quickly dropped when a blue tooth connection is active, giving an error:

I have three other Android phones running different Android OS. I will test the blue tooth issue on them and report back.      

Update from previous post. Tried battery optimization on the Sony Xperia Z1 Compact (Stamina, UltraStamina, Low-battery and Queued background mode) all off showed no difference in ANT sensors dropping out.

CycleBike+ app runs a MultiDevice Search periodically to find active sensors, then does requestAccess(). With Bluetooth active, I can either do MDS or connect to one ANT+ sensor. Multiple sensors also do not stay connected simultaneously. I've captured a Logcat file. PM me and I'll send the file with my findings.

No sensors drop out even with BT paired and connected, but still getting

I will test out some use cases and come back to you. Thank you for the quick response.      

Hello. First of all, sorry for my english.

As i wrote previously in this forum, i had continuous signal loses with my ANT+ sensors (cadence and HRM), and RunGPS or Endomondo. So i decided to use BT sensor for HRM and forget to register cadence, because i thought it was Android problem, not apps problem.

But today i installed a little app, called "Pulsometro RR" just for use in elliptical training, and i take a surprise because HRM doesn't disconnect (has a sound alarm if disconnected)

To test it in a longer training, i used both apps, setting sound alarm in the little app (to notice when disconnected) but this app holds connection and bigger apps disconnect as usual.

So maybe is not an Android problem

P.D.: When i first wrote in this forum i had Android 6, now have Android 7 with same device (Sony Xperia Z5 Compact)
