How to Set Up GPRS Data on IPLOG-GAMA G3

By default, the use of LTE mobile data for IPLOG-GAMA G3 is enabled. In the most cases, therefore, it is not necessary to change default configuration.

Check the Mobile Connection

Type command:

root@iplog:~# ifconfig wwan0

If mobile connection is active you will see similar output:

wwan0     Link encap:Ethernet  HWaddr AE:C9:12:92:2C:81
          inet addr:100.106.91.142  Bcast:100.106.91.255  Mask:255.255.255.0
          UP BROADCAST RUNNING NOARP MULTICAST  MTU:1428  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:56 (56.0 B)

Note: It's important that a line with an assigned IP address is present in the output. (Example: inet addr:100.106.91.142  Bcast:100.106.91.255  Mask:255.255.255.0

In the case any error occurs, for example:

ifconfig: wwan0: error fetching interface information: Device not found

Enable/Disable LTE Mobile Data Connection

Disable LTE Connection

To disable the automatic mobile data connection after boot, perform the following sequence of commands as root user.

1. Backup

It is recommended backup start up script S41lte before remove to posibility enable it again.

root@iplog:~# cp /etc/init.d/S41lte /etc/init.d/K41lte

2. Disable

Deleting file S41lte will disable automatic connection.

root@iplog:~# rm /etc/init.d/S41lte

Manual Connection/Disconnection of LTE Mobile Data. ==

Connecting

root@iplog:~# /etc/init.d/S41lte start

Disconnecting

root@iplog:~# cp /etc/init.d/S41lte stop

APN access point setting

Most mobile operators use for LTE access point called internet. This is the default setting and nothing needs to be changed if your mobile operator uses the same APN. In other countries, GSM network settings may be different. Therefore, we are introducing a simple way to change the APN.

1) Open the /etc/mbim-network.conf file in the text editor VIM

root@iplog:~# vi /etc/mbim-network.conf

2) The APN to use should be configured in this file, in the following way (e.g. assuming APN is called 'internet'):

APN=internet

 Optional APN user/password strings may be given in the following way:

APN_USER=user
APN_PASS=password

If APN user/password is specified, the authentication protocol to use (one of PAP, CHAP or MSCHAPV2) must also be specified in the following way:

APN_AUTH=protocol

Note: another important line for proper operation is as follows:

PROXY=yes

Note: Press the 'i' key in the VIM editor to editing text.

Note: To save the file in the VIM editor, press the Esc key and type ":x" (without the quotation marks) and then press Enter.

3) Do reboot

root@iplog:~# reboot

Automatic after boot

Enable

You need to have the startup script /etc/init.d/S41lte in the file system. This file is factory-created. If it is not, make sure that the /etc/init.d/K41lte file exists. If so, simply rename the file to /etc/init.d/S41lte. That is all. Otherwise, if none of the above files exists, you must manually create it.

1) Create the file as root

root@iplog:~# touch /etc/init.d/S41lte

2) Change access rights

root@iplog:~# chmod 755 /etc/init.d/S41lte

3) Open the /etc/init.d/S41gprs file in the text editor VIM

root@iplog:~# vi /etc/init.d/S41lte

Press the 'i' key to insert and paste the following content:

#!/bin/sh
#
# Starts the LTE
#

NAME=lte
PREFIX=/usr/bin
START_DAEMON=${PREFIX}/${NAME}_always_on
STOP_SCRIPT=${PREFIX}/${NAME}_off
PIDFILE=/var/run/${NAME}.pid

start()
{
        printf "Starting $NAME: "
        start-stop-daemon -S --background -p $PIDFILE --make-pidfile --startas ${START_DAEMON} && echo "OK" || echo
}

stop()
{
        printf "Stopping $NAME: "
        start-stop-daemon -K -q -p $PIDFILE && \
        rm -f $PIDFILE && \
        $STOP_SCRIPT > /dev/null && \
        echo "OK" || echo "Failed"
}

case "$1" in
        start)
                start
                ;;
        stop)
                stop
                ;;
        restart|reload)
                stop
                start
                ;;
        *)
                echo "Usage: $0 {start|stop|restart}"
                exit 1
esac

exit $?
