Hello,
I'm trying to use the set_start_time() command on a RFNoC: Radio block with a USRP X300. I am using the syntax to try to set the start time:
self.uhd_rfnoc_streamer_radio_0.set_time_next_pps(uhd.time_spec(0));
self.uhd_rfnoc_streamer_radio_0.set_start_time(uhd.time_spec(15));
However, the radio begins transmitting immediately after running the script instead of waiting for 15 seconds. Additionally, I know that there is no start time set in any of the packets sent to the radio, confirmed using a packet sniffer (wireshark).
I am trying to understand where the error in this setup is. Am I not using the correct syntax to set the start time, or are there some features that are not yet fully supported with RFNoC in GNU Radio? For reference, I am using version 3.7.12, which was installed with the rfnoc recipe in pybombs.
Thanks,
~Reggie
