Last yr (June 26, 2015) I convey a postal service to present how to “Import Android code sample of BluetoothChat to Android Studio“. It function perfectly AT THAT TIME. But I re-try it in 1 lawsuit to a greater extent than on update Android Studio 2.1, together with exam on ASUS Zenfont ii running Android 5.0 together with XiaoMi RedMi ii running Android 4.4.4; it most NOT WORK – no work inwards pairing together with connecting, only neglect to send/receive data: sometimes one-way chat, sometimes totally cannot chat!!!
Then I modify the Project Structure to target sdk version Android 4.4 (KitKat), it tin live on improved, only non 100%.
I convey no consider is it related to novel Android Studio/SDK? or related to novel Android version? or related to private device(s)?
