Hi All,

I need to re-initialize multi usrp object in my (c++) application on the runtime. How should I reset the multi usrp object? 

If I use reset command, it gives error on the runtime. 

Could anyone tell me what is the correct way to re-initialize the multi usrp object?

uhd::usrp::multi_usrp::sptr usrp;

string args="addr0=192.168.10.1,addr1=192.168.10.2";

usrp = uhd::usrp::multi_usrp::make(args);

uhd::usrp::subdev_spec_t subdev("A:0 B:0");

//receive and operate

...

//reinitialize usrp

usrp.reset();

string args="addr0=192.168.10.1,addr1=192.168.10.2";

usrp=uhd::usrp::multi_usrp::make(args);

uhd::usrp::subdev_spec_t subdev("A:0 B:0");

I am using usrp x310, ubuntu 14.04 and uhd 3.9 lts.

Best regards

What is it you wish to "re-initialize"??  You can always destroy the usrp object, and create a fresh one.

But in most cases, I don't see why you need to "reset" the usrp object.
