i updated my operating system yesterday and this morning i was unable to take measurement. did you get it resolved?
Just submitted a new case but I am having the same problem. Any update guys?
When you have upgraded to iOS 7 go into your settings, then privacy, select microphone, and switch to enable. That should resolve the bug we've been dealing with at BioForce.
This is counterintuitive when using the Bluetooth strap but it worked for me. First you have to turn off the "use bluetooth smart strap". Then go back to the "Measure" tab and it will ask you to use the microphone, obviously you have to say "yes" for measurements to work. Then re-enable the "use bluetooth smart strap" and re-pair your bluetooth strap. Finally got a good reading!
