rtl_tcp automatic startup on debian based distro ansible playlist

I just want run rtl_tcp on my OrangePi Zero automatically when fresh Armbian is installed. Setting up this process is just boring. I want it do simpler. Then ansible playlist idea was born.

When you turn on hotspot with armbian-config ( Google ) , connect powerbank, voilá you have portable RTL-SDR server.

The shitty thing is that wifi chipset is not good. When youre in high dense covered 2.4Ghz area, bandwidth to stream whole 2M is not enough.

The solution is probably change wifi channel, but chipset is still shitty 🙂 and you can see only slightly improvement. Another solution is 5G adapter. YMMV

Latest source code is @Github – https://github.com/pschonmann/rtltcp_startup_ansible. Tested on Armbian with Orangepi Zero
