Hello everyone,
I am fairly new to the SDR space and am learning as I go. I am trying
to run a simple FM RX flowgraph from GNU Radio on my host machine to
my USRP E310. I have verified that they are in the same network as I
am able to access the USRP via SSH, ping both machines on either side,
and can identify one another using /uhd_find_devices —args
addr=<USRP_IP_ADDR>/ and /uhd_usrp_probe —args addr=<URSP_IP_ADDR>./
When I generate and run the flowgraph, I get a runtime error stating:
/in __init__/
/self.uhd_usrp_source_0=uhd.usrp_source(
rpc::timeout:Timeout of 2000ms while calling RPC function ‘get_num_xbars’/
uhd_usrp_probe does give me a few warnings:
/[MPM.PeriphManager] Skipping Hw/SW compatibility check!/
/[MPM.PeriphManager] Found more EEPROM paths than daughterboards.
Ignoring some of them./
/[UHD] The buffer could not be resized sufficiently. Target sock buff
size 2500000. Actual sock buff size 1048576./
I ran /sudo sysctl -w net.core.wmem_max=2500000/ to increase the
buffer size.
My questions are, does this appear to be a problem with my flowgraph,
the USRP settings, or host settings? What are somethings I should look
into to solve this?
What happens if we ignore Gnu Radio for a second, and use an example
program like "rx_samples_to_file" ??
