-Let's back to the idea of sending a constant number to the PicoSDR and see if we get it back. First thing to do is to add a ''Constant Source'' block (with Int as Output Type, and whatever-you-want as the constant) (block can be found in category ''Waveform Generator''), and connect it to ''RTDEX Sink''. Now, how can we check that we receive the right number ? We could send it to a file and then check the file, but this ain't funny. Instead of this, we're gonna use a super cool new type of block added to GNURadio lately (As I am writing this tutorial). I'm talking about ''Python Block''. With this block, you can create a custom block, with its associated python code easily, without going through an OOT module. +Let's get back to the idea of sending a constant number to the PicoSDR and see if we get it back.

 Add a Python Block (from category ''Misc''), open it, and click on 'Open in Editor'. You can now edit the python code behind the block, and as soon as you save it, changes are repercuted to the block in GRC. You can either write your own code comparing two inputs or use mine : Add a Python Block (from category ''Misc''), open it, and click on 'Open in Editor'.
