Hi
I am using nrf52840 for indoor positioning application based on RSSI. I was wondering if somebody has a tip how to calibrate the nodes before doing the experiment.

What's your position accuracy requirement? Triangulation via RSSI is known to be pretty coarse. You'll also encounter multipath issues and need to handle orientation issues if using a chip antenna. If your environment is mostly static and confined to a specific room / building and you accurate positioning, perhaps you could pre-record RSSI values for each position your object could be in the area. Then try to figure out the position via correlating the current RSSI with those pre-recorded?
