It is my great honor to appreciate your works about GNURadio and USRP.
When I try to use the UHD driver,when I read the source code I have
about the use of the pure visual function for examples send(),
virtual size_t send( const send_buffs_type &buffs, size_t nsamps_per_buff, const tx_metadata_t &metadata, const io_type_t &io_type, send_mode_t send_mode, double timeout = 0.1 ) = 0;
The function send is a pure virtual function and I can not find it
is to be overridden anywhere else so I can not understand how it can
called by other functions and send the message.
//send a single packet
size_t num_tx_samps = tx_stream->send(
buffs, samps_to_send, md, timeout
from the programe tx_burst.cpp
I use the USRP2 and do not burn the SD card so can not use debug
tools to see how it works.
I am so appreciate if you can give me a hand!
