■ Button Behaviour:
In the Connected state, a Short button press stops the alert on the Security Tag if it is active; otherwise it triggers a
High alert on the remote Security Monitor.
In Idle state, a Short button press triggers advertisements and registers the pending High alert information, which will
be used to trigger a High alert on the remote Security Monitor once the connection is established.
An Extra Long button press by the user disconnects the link if any, removes bonding and starts advertising.
In Idle state, a Short button press triggers advertisements and registers the pending High alert information, which will
be used to trigger a High alert on the remote Security Monitor once the connection is established.
