Configuration through the web interface

Advanced Device Cloud settings
The default settings for Device Cloud remote management usually work for most situations. The
Advanced settings configure the idle timeout for the connection between the Device Cloud-
registered device and Device Cloud, and the keep-alive settings of the various interfaces (TCP and
HTTP for mobile and Ethernet network connections). These settings should only be changed when
the defaults do not properly work.
Connection Settings: These settings configure the idle timeout for the connection
between the Device Cloud-registered device and Device Cloud.
Disconnect when the Device Cloud Connection is idle
Idle Timeout: Enables or disables the idle timeout for the connection. If enabled, an
idle connection will be ended, after the amount of time specified in the Idle Timeout
setting.
Authenticate to Device Cloud with a password
Password: These fields are only applicable if your Device Cloud account has been
configured to expect a password from the Device Cloud-registered device. Typically,
this option is set through Device Cloud, as both the Device Cloud-registered device and
Device Cloud need to be configured identically.
Mobile (Cellular) Settings:
Ethernet Settings
WiFi Settings: These settings apply to device-initiated Device Cloud connections over
mobile/cellular, Ethernet, and Wi-Fi networks. Each network type has these settings:
Device Cloud Connection Keep-Alive Settings: These settings control how often
keep-alive packets are sent over the device-initiated connection to Device Cloud, and
whether the Device Cloud-registered device waits before dropping the connection.
Keep-alives for the Device Cloud connection serve three basic purposes:
1. Keep the Device Cloud connection alive through network infrastructure such as
routers, NATs and firewalls.
2. Inform the other (remote) side of the Device Cloud connection that its peer is still
active.
3. Test the Device Cloud connection to detect whether it has stopped responding and
should be abandoned. Recovery actions are taken as configured in other settings.
The Device Cloud-registered device and Device Cloud each perform their own
independent monitoring of the Device Cloud connection state (active, idle and
missed keep-alives). If Device Cloud protocol messages or data other than keep-
alives is exchanged over the Device Cloud connection, the idle timers that trigger
keep-alives are reset, and the consecutive missed keep-alive counts are cleared to
zero.
The interval settings are used with the Assume connection is lost after n timeouts
setting to signal when the connection has been lost.
Device Send Interval: Specifies how frequently the device sends a keep-alive
packet to Device Cloud if the Device Cloud connection is idle. Device Cloud
expects to receive either Device Cloud protocol messages or keep-alive packets
from the device at this interval.
