I want to minimize current consumption by switching from NORMAL to Low Power Mode 1 and to detect no-motion simultaneously.
That works. But when I'm trying to move BMA280 continually, no-motion interrupt is fired despite the fact that motion does persist. Tested with sleep_dur 0.5ms, 500ms, 1s. In NORMAL mode I see no interrupts by moving the device, and I do see no-motion interrupt when BMA280 is motionless.
Is that expected behaviour? Can I use no-motion & LPM1 together or not?

Right. If there are no changes in acceleration (theoretically constant velocity) for 300s, software timer will reach 300 and system will detect rest state. Neither ANY_, nor NO_ motion solves that case.
