Two Tx channels do not work simultaneously.

[tolstishka]

I'm trying to start emitting a signal from two Tx channels at once. HOWEVER, I was unable to obtain a working option, since the signal from both channels is emitted in portions in pulsation mode, that is, the signal is either not there.
Tell me how to properly launch two Tx channels on the device (using C++, iio-library and Linux)?

Any more information? SW setup? Device is accessed via USB or LAN?
For me in SDRconsole, does not care what port I choose, It always use TX1 only :/
I think SW needs still some improvements.
