Does Hackrf support GPS time-stamping the RF data?

[commthu]

I want to use GPS time stamping the RF data, does hackrf support this function.
I know some SDR device has this function. This is very useful in some applications.

This will probably require additional hardware like the PortaPack H1 and a GPS to sync with its RTC.
It may be possible to stream NEMA outputs into a GPIO but otherwise, this would seem to be a host software feature.

I wrote a gnuradio module to ingest NMEA data into your flowgraph. You could use that to write stream tagged samples to a data file... https://github.com/ckuethe/gr-nmea

And there it is...

Note that this module can't push any timing information into the receiver
so you'll probably get some pretty jittery timestamps depending on system
load.

GDB has a 'break' feature; why doesn't it have 'fix' too?

Thanks, ckuethe! I'm closing this issue as the remaining concern (timestamps implemented in firmware instead of on the host) already has an issue: #85
