I think you will find some of the links here informative:
Hi josh, thanks for your reply.
I created the usrp sink as follows:
uhd_usrp_sink_0 = uhd.multi_usrp_sink(“addr=192.168.10.2”,
uhd.io_type_t.COMPLEX_FLOAT32 , 1)
then I tried to get tx_stream using the following command
stream_args= uhd.stream_args_t(“fc32”)
tx_stream=tb.uhd_usrp_sink_0.get_tx_stream(stream_args)
but it gives the following error:
tx_stream=tb.uhd_usrp_sink_0.get_tx_stream(stream_args)
AttributeError: ‘uhd_usrp_sink_sptr’ object has no attribute
‘get_tx_stream’
Does this mean “get_tx_stream()” is not available in python? Also, can
you
please mention any python or GRC example that uses stream tags for
transmission time control? That would be great help.
in this example, there is an expensive operation of setting up the
transmit streamer thats happening with in the time specified, so I think
thats why you are seeing 300 milliseconds fail. I think the transmit
time in this case has become “late” when the USRP interprets the packet.-josh
There is a switch involved between the PC and USRP. I think that could
also
affect the value. Right?
