Experimental. MiYooSDR 0.2.0: a receive-only 2.4 GHz spectrum analyzer and waterfall for the Miyoo Mini Plus, built from the handheld's own RTL8188FU Wi-Fi chip. No SDR dongle or extra hardware.

New in 0.2.0

  • Filled, multi-colour spectrum with a lit top edge, a Wi-Fi band shading view, and four palettes (Ember, Spectrum, Ice, Matrix). Cycle with SELECT+Y and SELECT+A.
  • Channel occupancy (SELECT+B): per-Wi-Fi-channel activity bars to spot a clear channel.
  • Signal-to-sound (SELECT+X): a tone whose pitch tracks the level under the cursor, handy for direction finding.
  • Review mode (SELECT+START): browse and replay saved recordings on the handheld.
  • Single-channel burst recorder: miyoosdr --burst <MHz> <seconds> logs power-vs-time at high rate.

Requirements

  • A Miyoo Mini Plus (the plain Mini has no Wi-Fi chip and will not work).
  • OnionOS with its stock 8188fu driver.

Install

Download miyoosdr-0.2.0.zip, extract to the root of your SD card (it lands as App/MiYooSDR), and launch MiYooSDR from Onion's Apps list. Wi-Fi goes offline while it runs and returns a few seconds after you quit. Levels are uncalibrated; it is receive-only and cannot decode signals. Controls are in the README.
