1 metre accuracy? To the best of my knowledge - no.

Perhaps for <1m, 1-10m, >10m - and very roughly at that.

You could attempt a test set-up to measure and calibrate for your device and your environment - but the moment anything changes (e.g. a person in the room moves a few inches) - then the RSSI values will likely change significantly.

Yes i am getting near and far. bus is there any method to get 1M accuracy using RSSI? if no signal reflections, orientation of antennas problems?

RSSI is a very unreliable parameter for determining distance. It's strongly affected by signal reflections, orientation of antennas etc.

Typically you can get a rough indication of "very close", "far away" or "somewhere in-between those two".
