Dear all, there is a lot of uncertainty with the electronics and respective software to use, and documentation is non-present. I am updating them on the go. However we should clarify some base line decisions.
The OpenWRT was originally intentend to run rtlsdr and rotctl. However the version of rtl-sdr is still archaic old (2014) and there were some bugs reported (and fixed) years ago. A new problem is that on the later OpenWRT releases by default there is not enough space for hamlib and rtlsdr.
My question then: Do you currently use the OpenWRT for rtl-sdr at all anyway? All tasks can be easily performed by the Raspi/Odroid anyway.
