Data connection procedure using PPP

• Place a data enabled mini-SIM in the SIM card slot and connect a GSM antenna to the respective 2G/3G antenna connector.
• Ensure that the power jumpers J2 and J3(ignore if battery feature present) on VIBE2 are in place and eeprom address set at 0x54 using dip switch S7
• Power up VIBE2 using the 5V, 5A DC adapter (supplied with VIBE2).
• After powering up and bootup, ssh into VIBE2 through Ethernet Cable (at IP 192.168.1.150 for preflashed eMMC images)

ssh -l root 192.168.1.150

• Username for root login is root and password is root. For user login, username is debian and password is temppwd.

• Then you have to check modem using lsusb command.

Note: Please ensure that the user leds on the board is glowing according to its functionality after booting/powering the board.

root@Yantrr:~# lsusb

• Now there are two ways to setup ppp0 connections:

a. ppp daemon

• For setting it, you have to open /etc/ppp/peers/airtel file (we used airtel SIM).

nano /etc/ppp/peers/airtel

• From the opened window, you can verify the username for your service provider.

hide-password
noauth
connect "/usr/sbin/chat -v -f /etc/chatscripts/airtel"
debug
/dev/ttyUSB3
460800
#defaultroute
replacedefaultroute
noipdefault
user "airtel"
remotename airtel

• Now you can use pon command.

pon airtel

• You can check whether ppp0 connection is up or not.

root@Yantrr:~# ifconfig

• Now you can check connections using commands given further in the document.

b.Wvdial

• First we will setup ppp0 connections using wvdial.
• For this you have to install wvdial tool using command.

sudo apt -get install wvdial

• Now we have to set the configuration of wvdial using wvdial.conf file. For this type

nano /etc/wvdial.conf

• Assuming that you have the USERNAME, PASSWORD and APN available for the service provider of the SIM card being used, edit and make wvdial.conf file like this. Sample Wvdial files for some service providers are given HERE
• NOTE: Also verify the modem port mentioned in the wvdial.conf file with actual modem port.

For ZTE model- /dev/ttyUSB3

For SEW Strong Rising model- /dev/ttyUSB0
