I'm trying to use the gr-sdrplay3 module with python and it's generally going well. I was wondering if there is a command for timestamping ? I'm trying to find the equivalent of this line for UHD / USRP

self.uhd_usrp_source_0.set_time_now(uhd.time_spec(time.time()), uhd.ALL_MBOARDS)

Thanks!

@ghassel - I am glad to hear that you found this module useful.

Unfortunately the SDRplay RSP devices do not have time registers like the UHD or any way to say use a PPS signal; you can use an external clock from a good reference like a GPSDO, but that is not enough to provide a time reference.
