AntiLost

Introduction

BLE GATT services advertised

This page is about so-called "anti-lost" tags and how to communicate with them.

This allows them to implement the following functions:

• read out general characteristics of the anti-lost, like the name
• read out battery level of the anti-lost
• enable beeping from the client
• notify when the button is pressed on the anti-lost

Also:

• start beeping when the connection is lost (silenced by a button press)

They do this by implementing a BLE GATT server, with a bunch of services.
