Baofeng MP31 programming software
Open WebCHIRPWebCHIRP programs the Baofeng MP31 in your browser. It runs the CHIRP project's own driver for this radio, so it reads and writes the same codeplug the desktop software does — without installing anything.
No driver install needed
Baofeng programming cables use a CH340, CP2102, PL2303 or FTDI USB-serial chip. WebCHIRP speaks to all four directly from the browser, so there is no driver package to download and no Windows version to match. Plug the cable in and pick the port when the browser asks.
