i have half duplex daughterborad and using gnu-radio flowgraph to
transmit and receive in alternate time. i founded that while running the
code both A, C Leds in USRPn210 are on. IS that indicate that i send and
transmit? if ok how this while i am using half duplex daugher board.
Note: i sue python codes for transmitting and receiving over the USRP
but only one runs at time and other gives me error that the address not
defined. But both works alternatively.
can an one send me the illustration for this Problem and how to overcome
and solve it

You can only have the device open in one process. So your transmit and
receive chains should be in the same process.

thanks josh , But when i run the grc file both leds on . how this ?also
when i made calculations for the transmitted signal power it is -6e-5db
and received signal power is -90 db. which is noise , that means that i
am not receiving or transmitting any signal although both leds on.
