Time of flight with nrf52

[bds]

Did anyone attempt time of flight measurements with the nrf52 yet? I'm looking into this as a possibility to measure distances. I was thinking that using the 64 MHz clock, a resolution around 3m should be possible. Further averaging could give a resolution close to 0.5m. Any thoughts/experiences?

The topic has been discussed a couple of times here on devzone, but I'm not aware of any real implementations using time of flight. Here is also a somewhat relevant blog post: Wireless timer synchronization among nRF5 devices.

Note that although the CPU on the nRF52 runs at 64 MHz all of its peripherals only run at 16MHz which I guess will degrade your resolution.
