ESP32 BLE Mouse Jiggler

A device which periodically randomly perturbs the mouse, for keeping you active on chat media, stopping screen savers from kicking in etc

It's a BLE HID peripheral that identifies as a mouse. It's indistinguishable from a regular bluetooth mouse, because it is a bluetooth mouse.

setup

. ~/export-esp.sh
cargo generate esp-rs/esp-idf-template cargo     # simple templates, target esp32
cargo add esp-idf-hal esp-idf-sys anyhow esp32-nimble

build

cargo run

use

Flash an ESP32 board (I used an AdaFruit Huzzah ESP32, but any variant should work) with the code:

cargo run

I built mine into an old film canister and powered it from the monitor's USB port:

Then on your target computer, enable Bluetooth and pair with "BT Mouse". For some reason it later changes its name to "nimble" on a mac, not sure what that is all about.

Every 60 seconds, it will give your mouse a little jiggle!

If you monitor the debug console you'll see this when it jiggles:

To change the interval, edit the timeout in the last line of src/main.rs.
