This page shows how to set up the Lilygo T-Watch S3 to work as part of the handshake project.

Summary

Turn on the watch using a long press on the button.

Shake the watch gently and check that this is detected as a switch by the receiver unit.

Adjust the level of shake that will trigger a switch action using the jog dial on the receiver, followed by a long press on the button in the middle of the jog dial. This sends the new shake detection threshold to the watch.
