Timeouts

Most mobile networks use stateful firewalls or NAT where the timeout for UDP is approximately 1-2 minutes. If this
applies to you, we suggest either configuring the LwM2M client with a registration lifetime that falls within this
period (e.g. 60 seconds) or using the queued ("UQ") UDP binding mode.

GPS

On models with a built-in GPS, you are able to use location-based services, monitor field deployed hardware or
find your current location. The GPS Status window provides up to date information about the current location and
the current GPS signal conditions (position dilution of precision (PDOP), horizontal dilution of precision (HDOP)
and vertical dilution of precision (VDOP)) of the router.

NMEA support

The router supports the National Marine Electronics Association NMEA-0183 compatible (V2.3) standard of
sending GPS data. The standard includes "sentences" used to identify the type of data being sent and therefore
defines the way the data is interpreted. The supported GPS related sentences are listed below:
GPGGA – Global Positioning System Fix Data, Time, Position and fix related data for a GNSS receiver
GPRMC – Recommended minimum data for GPS
GPGSV – Detailed satellite data
GPGSA – Overall satellite data
GPVTG – Vector track and speed over the Ground

GPS configuration

To access the GPS configuration screen, select the Services item from the top menu bar then the GPS item on the
left. Finally, select the GPS configuration menu item.
To use the GPS function, set the GPS operation toggle key to ON and click the Save button.
NTC-220 – User Guide
UG01028 v1.2 March 2019
When 'Override Settings' is enabled, this allows you to specify
whether to report the UDP binding mode to the server as queued
("UQ" binding mode) or not ("U" binding mode.)
When 'Override Settings' is enabled, this allows you to choose
the security mode that will be used to connect to the LwM2M
server. Currently supported options are 'No Security' and 'Pre-
Shared Key'.
When PSK security mode is selected this field is where you must
specify the identity string associated with your pre-shared key.
When PSK security mode is selected this field is where you must
provide the pre-shared key. The key must be entered as a
hexadecimal string.
