Block that receives a " message" and send string values over serial connection, to control hardware devices ( switch ), for example, via Arduino based controller ( see https://sourceforge.net/projects/ardu-switch/ )
Prerequisite: pyserial
Build as usual for a Gnuradio block:
- download and unpack
- cd gr-message_to serial
- mkdir build && cd build
- cmake .. && make
- sudo make install && ldconfig
If successful this block is into OOT section... Enjoy ;-)
