Distance Measurement Accuracy

Question

Hello and thank you for your help. 
 I am working with the nrf52840 for a project that uses distance estimates. I have tried the sample Bluetooth: nRF Distance Measurement with Bluetooth LE discovery using MCPD. Can I check if there are any accuracy estimates for the MCPD ranging mode or any tested margin of error? I would like to see if the measurements I am getting are within the expected range. 
 Thank you.

Hi 
 Please check out the slides from the Nordic distance toolbox webinar available here . In high precision mode you can see that the standard deviation is ~37cm, which is for example in an office environment with a lot of noise this gives reliable results up to 10 meters. In less noisy environments this increases, but testing should be done to find what you can expect. 
 Best regards, 
 Simon
