ESP Web Tools brings USB firmware installation to Chrome on Android. Makers can connect a supported ESP device to a phone or tablet through a USB-C cable or USB OTG adapter, without installing desktop drivers. Chrome’s native serial picker on Android previously listed Bluetooth devices rather than these USB boards.
Jesse Hills adds support for native USB devices and the CP210x, CH340/CH341 and FTDI serial bridges used by many ESP boards. Complete installations were tested on a Pixel through CP2102, CH340 and FTDI connections at 115,200 baud; faster transfers were not tested.
The logs view fills a phone’s screen and stays above the on-screen keyboard, keeping its command field and controls reachable. During installation, the tool requests a screen wake lock where supported to reduce interruptions when the display would otherwise sleep.
