dataloger no log or data stream

[military]

Hi, connect dataloger, set the time, insert preformated FAT32 16GB sd card, green led On, connect phone - blue led On, but NO data on phone (all gauges show zero) and no data log on SD.
In Ext. Port - devices - emu serial dataloger.
Maybe I forgot somethink to enable?
