XTRX GPS Lock status

Hi, is there a way to check the GPS lock status of the XTRX board?
It looks like limeDevice -f has some support for it, but that doesn’t seem to be working for the xtrx currently (it’s showing up as undefined, rather than one of [Not available, 2D, 3D]):

$ limeDevice -f

These are just interpreted register values read from FPGA, I’m not sure if it’s implemented in the XTRX gateware.

Hi @0x12BFB9FA,

this functionality is not implemented yet in current gateware.

Ah, thanks for the responses - is this just the indication of whether it’s locked or not that’s not there yet, or GPS calibration of the oscillator/improved accuracy when the device has a GPS signal overall? Either way would be useful to have it!
