For the complete description and syntax of the AT commands supported by SARA-R5 series modules,

see the SARA-R5 series AT commands manual [1].

For detailed AT commands examples for network registration and configuration, context activation,

data connection management, SIM management, module interfaces configurations and other

settings, see the u-blox SARA-R5 application development guide [4].

C.1 Define the initial default bearer for connectivity

To change the PDN settings for the initial default EPS bearer established during LTE attach, edit the

<cid>=1 PDN by means of the +CGDCONT AT command.

Command sent by DTE (user)

DCE response (module)

Description

AT+COPS?

+COPS: 2

OK

The module is not registered.

AT+CEREG=2;+CGEREP=1,1

OK

Enable a set of registration URCs.

AT+CGDCONT?

+CGDCONT: 1,"IPV4V6","","0.0.0.0

0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",

0,0,0,2,0,0,0,0,0,0

OK

Read IP type and APN for EPS attach

bearer.

AT+CGDCONT=1,"IPV4V6","broadband"

OK

Set the APN name ("broadband" for

example) and the PDP type ("IPV4V6" for

example) for EPS attach bearer.

AT+COPS=0

OK

+CEREG: 1,"0001","01a2d001",7

+CGEV: ME PDN ACT 1

Trigger a network registration and wait

for attach complete.

C.2 Data connection using internal TCP/IP stack

Activate an internal context to use the internal TCP/UDP stack.

If an external "IP" context is active, just map the external context to an internal one.

Command sent by DTE (user)

DCE response (module)

Description

AT+CGDCONT?

+CGDCONT: 1,"IP","default.mnc321.

mcc654.gprs","192.168.20.6",0,0,0

,2,0,0,0,0,0,0

OK

Read IP type and APN for EPS attach

bearer.

Context <cid>=1 has IP type "IP" and

APN "default.mnc321.mcc654.gprs".

AT+CGCONTRDP=1

+CGCONTRDP: 1,5,"default.mnc321.m

OK

Read context <cid>=1 dynamic

parameters.

<cid>=1 is currently active with IPv4

address 192.168.20.6/24, gateway

192.168.20.1 and DNS server

185.215.195.114.

context <profile_id>=0.

AT+UPSDA=0,3

OK

+UUPSDA: 0,"192.168.20.6"

Activate internal context <profile_id>=0.

A URC is received indicating activation

complete and IPv4 address for the

internal context.

If an external "IPV4V6" context is active, configure the internal context with type "IPv4v6 with IPv4

preferred".
