You will need to call recv_async_msg() (see: http://files.ettus.com/manual/classuhd_1_1device.html#a18f94b4369ebfa03358b06bef000dacd). It will return a uhd::async_metadata_t (see: http://files.ettus.com/manual/structuhd_1_1async__metadata__t.html). Check if it's an underrun, then you have the timestamp. > Also, setting these two env variables doesn't have any effect on logging: > > UHD_LOG_LEVEL On 3.9, we used a somewhat counter-intuitive log level format. These are valid log levels: https://github.com/EttusResearch/uhddev/blob/b21276c415ee0046eda6c7af94e89ae4cb859c9c/host/include/uhd/utils/log.hpp#L73-L80 > UHD_LOG_FILE This was added in 3.11. In 3.9, it would always log to uhd.log in a temp directory. -- M > > I built UHD myself and I didn't use any cmake options other than setting > CMAKE_INSTALL_PREFIX, which I don't think has any effect. > > Thanks for any help, > Devin > > > _______________________________________________ > USRP-users mailing list > USRP-users@lists.ettus.com > http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com > _______________________________________________ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com
