Hello,
I’m using LimeSdrMini2.2 with GnuRadio3.11 under Ubuntu2025.10.
Now, with my GnuRadio FlowGraph, I get a sporadic error of this kind:
<thread_body_wrapper :error: ERROR thread[thread-per-block[28]: <block sdrdevice_source>]: argument not found>
and the stream is stopped.
After this Error, I get warnings of this kind:
<LimeSuiteNG 
USB ep:83 Rx0: 7.760 MB/s | TS:132435780 pkt:129840 o:1289(+1289) l:0(+0) dma:8115/8116(+1) swFIFO:470>
What I have already tried is:
I expand the batch buffer for Rx and Tx to 16, but without success.
I’m searching for ‘argument not found’ but without result.
I am not sure, if this is a problem of LimeSuiteNG or GnuRadio?
But if I replace the ‘LimeSuiteNGSource’ block to ‘SoapyLimeSDRSource’ block
in my GnuRadio flowgraph, all works fine without error.
This points the problem to LimeSuiteNG…
Has everybody an idea what goes wrong, and witch argument is not found?
Thanks
