Title: Distance Measurement Shows Double the Actual Value on nRF52840

I am using an nRF52840 and  nrf52832 to measure distance, but the reported value is almost twice the actual distance. For example, when the actual distance is 1 meter, the reading is around 2 meters.

What could be causing this issue? Is there a setting or calibration step I need to adjust in the Nordic SDK?

I am currently working on this project and would appreciate a quick response.

  • Still pretty incredible that it can do that resolution.

    Then I started thinking how it would be done without a much higher clock and I thought if the receiver was able to echo the signal with a known latency then the required clock would be half and only one precision clock would be needed. Even so that's still high but if there was multiple echoing each time would half the clock requirement at the expense of doubling the time needed to do the measurement.
