Re: [Discuss-gnuradio] USRP block to receive signal periodically

[Zhihong Luo]

Hi Martin,

It seems that using stream_cmd by "issue_stream_cmd" is only for C API. But if I want it to be Python, since there is no component "stream_cmd_t", how can I control the streaming in Python?

Thanks,

Zhihong
