Re: [Discuss-gnuradio] GNU Radio 3.7.12 RFNoC set_start_time()

2017-11-15 Thread Derek Kozel
Hello Reggie, I believe the issue you are encountering is that the streaming starts before the next PPS edge arrives and resets the USRP time to 0. Try adding a sleep for one second between the set_time_next_pps and the set_start_time. Some RFNoC features are not fully exposed in GNU Radio, but mo

[Discuss-gnuradio] Question on number of input items per work call

Hi all I am experimenting with my own python block. I started by simply interrogating each variable to see their types and shapes. I connected a vector source that just generates increasing numbers (0, 1, 2, 3, 4, 5 and so on upto a big number). I noticed that the length of (input_items[0]) s
