Hi. I have an m5 Xperia. I use an app called librelink to manage my diabetes. Librelink allows me to scan a freestyle libre sensor installed on my body. I was running Android 5 and the app worked fine. I upgraded to marshmallow android 6 last Saturday. Immediately the app stopped being able to scan the sensor and read it. I tried reinstalling the app and it still would not scan. So on Sunday I undertook a full reset. I again reinstalled librelink and it still does not work.
I have switched nfc on and Android beam is on. However occasionally I get an error message whilst the app is open saying nfc is not enabled even though in the settings it is saying it is.
I have tried other apps that do a similar thing to librelink called glimp and liapp and these also will not scan using nfc.
Anyone got any ideas?
