! Access point defines the APN used to connect to the Internet. For more
information on setting the APN see section 1.2.1 Network Connections. Your
service provider can give more information about access points.
! Keepalives defines if EMO is allowed to send keepalive signals. The
recommended option is Automatic, which means that the device starts sending
keepalive signals only if it notices that the network connection is lost
periodically. The purpose is to ensure a connection in networks where an idle
connection is automatically cut after a certain period.
The option On means that the device sends keepalive messages with 2-minute
intervals. Each message is approximately 10 bytes in size.
The option Off means that keepalives are not sent from the device.
Keepalives are always sent from the server side at 15-minute intervals. If
keepalives are on (either with the setting On or Automatic), and there are
excessive disconnects, EMO goes to Paused mode. Paused mode is indicated to
the user by bringing the setting screen to the front to inform the user that EMO
is paused. The purpose of the keepalive logic is to avoid extensive connection
charges in networks where there is a per-connection fee. Charges may be
considerable, particularly when roaming.
