util/bridge.py doesnt work on windows because "MSG_DONTWAIT" doesnt exist on windows
i tried to delete it & fix the code but

sdrpp: doesnt show anything

gnu radio:

OSError: [Errno 9] Bad file descriptor`

gqrx: freezes & crashes

i did million things to get here on windows and 100 lines of python blocking me :( help would be awesome

edit: running grc/PicoSDR.grc or PicoSDR-WBFM.grc output:

Executing: C:\Users\TOSHIBA\radioconda\python.exe -u C:\Users\TOSHIBA\Desktop\picosdr\pico-sdr\grc\PicoSDR.py

built-in source types: file rtl rtl_tcp uhd miri hackrf bladerf airspy airspyhf soapy redpitaya

and it just waits until i stop it. no waterfall etc shows up

tips for fellow windows users; install arm-gnu-toolchain, libusb, pico-sdk, picotool and you need mingw, dont dorget to set all their paths, follow this for compiling picotool

Yeah, sorry. I don't really wish to spend any time on Windows support. Feel free to submit a patch, though.
