It looks like the timeout rule was changed and now the sequence provided in the
initial
post generates an Overflow, possibly corrupting the buffer and restarting the
communication
at a random time.
Reducing the delays to
curr_hw_time = self.uhd_usrp_source_0.get_time_last_pps()
self.uhd_usrp_source_0.set_time_next_pps(
uhd.time_spec_t(0.5)+curr_hw_time)
time.sleep(0.1)
self.uhd_usrp_source_0.set_start_time(uhd.time_spec_t(1.01)+curr_hw_time)
seems to restore the functionality. Solution courtesy of Gwenhael Goavec-Merou.
Best, JM
