rtl_tcp compatible server for the LimeSDR Mini

I recently acquired a new LimeSDR Mini USB SDR module. Not much bigger than an RTL-SDR, 10 MHz to 3.8 Ghz frequency range, 12-bit sampling, full-duplex, capable of a wider bandwidth than a Raspberry Pi can use.

In order to test the receive function of the LimeSDR Mini using my existing SDR applications, I wrote an rtl_tcp compatible IQ server.

The source code to my lmm_tcp server is posted on GitHub: https://github.com/hotpaw2/lmm_tcp

Using the lmm_tcp server, I can the plug a LimeSDR Mini into a Raspberry Pi 3, then view an RF waterfall and listen to demodulated audio on my iPhone or iPad, using either my rtl_tcp SDR app, or the SDR Receiver iOS app.
