[time-nuts] 10MHz LTE-Lite - PPS accuracy?

Don’t do it. 😊


Quite simply - if you either execute ldattach pps /dev/ttyUSBx, or are running GPSD (recommended) it will bind the USB appropriately to a ppsapi instance.


Do not do it.  You will not approve of the results.

I'll admit, to my shame, that I have yet to deduce how to use USB provided
DCD for PPS.
I've looked,  really I have but to no avail.

I see that the code has been in the driver circa Linux 2.6 but I'm just not
making the "connection".
