You can call all usrp.set_time* API calls to set the device time. However, this has nothing to do with stream tags. http://files.ettus.com/uhd_docs/manual/html/sync.html#synchronizing-the-device-time Also, you can use my grblock work to write blocks in python and to read/write tags. See the examples/tags_demo.py for a use case. https://github.com/guruofquality/grblock -Josh _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
