6.3.1 Notifications and Indications While Disconnected
If a client has configured the server to send a notification or indication to the
client, it shall be configured to allow re-establishment of the connection when it
is disconnected.
If the client is disconnected, but intends to become a Central in the connection
it shall perform a GAP connection establishment procedure. If the client is
disconnected, but intends to become a Peripheral in the connection it shall go
into a GAP connectable mode.
A server shall re-establish a connection with a client when an event or trigger
operation causes a notification or indication to a client.
If the server is disconnected, but intends to become a Peripheral in the
connection it shall go into a GAP connectable mode. If the server is
disconnected, but intends to become a Central in the connection it shall
perform a GAP connection establishment procedure.
If the server cannot re-establish a connection, then the notification or indication
for this event shall be discarded and no further connection re-establishment
shall occur, until another event occurs.
