Hi,

I am trying to use two USRP (B210) in one laptop.
I plan to send signals using two USRPs from the same source.

When I tried to separately run ".grc" file in each terminal, it works correctly.
However, when I tried to add one more "UHD: USRP sink" block in GRC.

It shows an exception message "S" and only one USRP works.

Could anyone help me to solve this problem?

(1) What is the meaning of "S"?
O: overflow, U: underflow, but I don't know what this is.

(2) Is there any way to use multiple "UHD: USRP sink" blocks in one machine?

Thank you,

What sample-rate are you using?   Is this over USB2.0 or USB3.0?

Could you share your .grc file?
