N210 not producing output with GRC

Hi,

I have a N210, which when I try to use with GRC (UHD USRP single
source block) produces at the console:

Current recv sock buff size: 50000000 bytes
mboard0 MIMO master
UHD source block got error code 0x1
gr_block_executor: source <gr_block uhd single_usrp source (2)>
produced no output. We’re marking it DONE.

Parameters I set for the block:

self.uhd_single_usrp_source_0 = uhd.single_usrp_source(
  device_addr="addr=192.168.10.2",
  io_type=uhd.io_type.COMPLEX_FLOAT32,
  num_channels=1,
)
self.uhd_single_usrp_source_0.set_samp_rate(samp_rate)
self.uhd_single_usrp_source_0.set_center_freq(250e6, 0)
self.uhd_single_usrp_source_0.set_gain(0, 0)

I left the Subdev Spec and Ch0: Antenna field blank. I’m using a WBX
RF board with TX/RX side antenna connected. I’m able to transmit using
the tx_waveforms example, and I know it is transmitting.

Help,
Arya

This is probably a newbie answer but I see you have the gain set to
zero, does that make a difference?

Is this mac osx? What happens when you run examples/benchmark_rx
–rate=10e6?
