Very alpha version.

NanoVNA interface implementation with WebUSB.

2. Access to https://cho45.stfuawsc.com/NanoVNA/ .
3. Connect your NanoVNA to USB port.

Some OSes are additional requirements:

Requirements

macOS

no requirements

Android

Connect device via USB OTG connector. (Type-C to Type-C cable may not be usable. I recommend using USB-A OTG adapter.)

Linux (Ubuntu)

Copy 99-nanovna.rules to your /etc/udev/rules.d.

BE CAREFUL: This rule disables cdc_acm driver for all STM32CDC devices (vid:0x0483, pid:0x5740). So, If you want to use device as usb cdc device, you must remove this file again.

Windows

Replace driver with Zadig.

Screenshots
