[Discuss-gnuradio] USRP underflow issue

[irene menicagli]

Hi everyone,

I’m new to Gnuradio and I have some problems with USRP N210 with WBX daughterboards. I send data coming from udp socket to USRP and I am encountering underflow issue.

I think that problem is due to the rate of the data transmitted to USRP. I have tried to set the sample rate in the USRP using different values. Only with the lowest value, 200 ksps, it seems to work (no underflow) but increasing the sample rate underflow appears.

Moreover, I have repeated the test with 200 ksps more than once with the same configuration and in some cases underflow appears.

Could you please help me?

Thanks

Irene
