Good. Finally, trend upload from DT-9979 works. There are some things which SHOULD BE FIXED: 1. Ability to log BOTH AC & DC measurements in AC+DC modes. Since Android receives BOTH readings (as should be seen by dual AC & DC display), it is very simple software fix. 2. Increase readings speed from 1 per second to several per second at least. 3. Fix trend graph: it gets garbled when changing screen orientation. 4. Fix fonts: they are almost unreadable (Nexus 5, Android 5.1.1) 5. Add ability to update firmware and change DMM settings (remote control).
* Update for meter model FI279MG support;
* Fixed some bugs.
