Calling rtlsdr_* while receiving in async mode

by Oliver Jowett

What's the "right way" to call rtlsdr_* functions while receiving samples via rtlsdr_read_async()? e.g. to change frequency or gain mid-run. You can't call them directly from the async callback as you're within a libusb callback at that point and libusb will self-deadlock if you do anything that needs a synchronous transfer. Plus even without the self-deadlock you really don't want a recursive callback happening if another bulk transfer turns up.. You can't call them from a separate thread because librtlsdr isn't threadsafe. The only way I've found that's reliable is to call rtlsdr_cancel_async() from within the async callback, wait for rtlsdr_read_async() to return, do your work, then call rtlsdr_read_async() again. This is ugly and can drop samples. rtlsdr_read_async() is also a bit buggy in that sometimes it will take up to a second after cancellation has completed before it returns (it calls into libusb to handle more events even if all xfers have completed cancellation, and then you've got to wait for that to time out..) What's the right way to do this? Oliver

A rtl-sdr driver fork for #Sdr-Sharp was created with software decimation

by rtlsdrfan＠airmail.cc

It seems a Russian developer created a fork of rtl-sdr that has software decimation. "The decimation feature allows you to sacrifice some bandwidth for increased ADC bit resolution." This may be a reimplementation of the sdr-sharp version of decimation according to this story: http://www.rtl-sdr.com/new-sdr-rtl-sdr-driver-lnamixervga-gain-settings-dec… The driver also features manual settings for the LNA/Mixer and VGA gain stages and is based on Oliver Jowet’s modified driver. The source code is here: http://sourceforge.net/projects/sdrr820tmanualgainsettings/files/ if anybody wants to see if there are any notable changes worthy of making a patch or pull for as it may contain other fixes or features.
