Digi XBee Cellular LTE Cat 1 Embedded Modem User Guide

AN (APN)
Sets or reads the Access Point Name (APN) the device uses to connect. The APN must match a valid
value for the carrier.
CAUTION!
Send
ATNR0
to reset Internet connectivity any time that you change
AN
.
Failure to do so can cause usability problems with the XBee Cellular Modem.
If
AN
runs with no value, the command responds with a cached copy of the active APN value. When the
XBee Cellular Modem is turned on, this value is empty and is queried from the cellular component
settings and is cached once per minute.
If
AN
runs with a value, the XBee Cellular Modem holds that value in memory until the next time
Internet connectivity is established.
AN
is not case sensitive.
AN
may return an APN that matches everything except the case; this is
acceptable and is not an error.
Parameter range
0 - 99 ASCII characters
Default
-
NR (Network Reset)
NR
resets the network layer parameters.
The XBee Cellular Modem responds immediately with an
OK
on the UART and then causes a network
restart.
If
NR
= 0, the XBee Cellular Modem tears down any TCP/UDP sockets and resets Internet connectivity.
You can also send
NR
, which acts like
NR
= 0.
Parameter range
0
Default
N/A
!R (Modem Reset)
Forces the cellular component to reboot.
CAUTION!
This command is for advanced users, and you should only use it if the cellular
component becomes completely stuck while in Bypass mode. Normal users should never
need to run this command. See the
command instead.
