Re: [Discuss-gnuradio] Setting buffer size when using UHD

[Per Zetterberg]

I read the page you refer to but I don't understand. Is this correct ?

uhd::device_addr_t dev_addr;
dev_addr["addr"] = "192.168.10.11 192.168.20.11";
dev_addr["addr"] = "192.168.10.11 192.168.20.11";
dev_addr["recv_buff_size"] = "1e4";
d_mdev=uhd::usrp::mimo_usrp::make(dev_addr);

Yes. But then I need to do change this value when depending on which 
application I about to run or ... ?
