2 years ago You may find the answer in this thread, https://groups.io/g/airspy/topic/hf_scanning_with_hf/90429763 That timeout appears to be cause by change to blocking in readStream ( https://github.com/pothosware/SoapyAirspyHF/commit/5f6b6909a750a6ef6d71d5e4a4f4bb95602d5e4b and the link in that where they explain the issue has changed to be https://github.com/pothosware/SoapySDRPlay2/issues/68 ). The original timeout assumed that the stream was active and had a fault, basically it did not have to deal with any extra setup delays for the very first buffer.
Maybe two timeouts are what is needed one for the initial buffer and a second lower value timeout for the normal steady state stream. The simple workaround of increasing the timeout to be an order of magnitude larger or more is a sub-optimal solution.
Can someone share, tested and working system, which version of libraries are actually working , I will do downgrade, never mind.
I have SoapySDR 0.8.1 soapy-power 1.6.1 SimpleSoapy 1.5.1 last update from 2017
System is arch linux Linux lenovo-lap 5.15.33-1-lts #1 SMP Fri, 08 Apr 2022 13:43:36 +0000 x86_64 GNU/Linux
airspy drivers are from AUR which is latest, but I also try with downgraded drivers, which I compiled.
