Hello my friends,

    I have a beagleboard Angstrom running on it. I try to connect to
the internet with Huawei 3G modem. Although the beagleboard can
recongize the device as Huawei when i type command lsusb, i cannot
connect to the internet. How can i succeed it, do you have any idea?

I guess can help you with that,
I don't have a beagleboard but i have a leopardboard and successfully
connected to TCELL 3G network.

You have to follow following steps.

- Install pppd
- Build the kernel with usb to serial module.
- Configure the pppd with correct chat scripts.

Install the modules with

cat modules.sh
#!/bin/sh

insmod /lib/modules/2.6.29-ridgerun-davinci1/kernel/drivers/usb/serial/
usbserial.ko vendor=0x12d1 product=0x1003
insmod /lib/modules/2.6.29-ridgerun-davinci1/kernel/drivers/usb/serial/
option.ko

This is the chat script for
cat chat.connect
'' AT
OK ATZ
OK AT+CGATT=0
OK AT+CGQREQ=1,0,0,0,0,0
OK AT+CGQMIN=1,0,0,0,0,0
OK AT+CGDCONT=1,"IP","mgb"
OK ATE1V1&D2
OK AT+IFC=2,2
OK ATD*99***1#

CONNECT \c

cat provider
connect "/usr/sbin/chat -v -f /etc/ppp/peers/chat.connect"
disconnect "/usr/sbin/chat -v -f /etc/ppp/peers/chat.disconnect"
/dev/ttyUSB0
4000000
debug
#nodetach
dump
noauth
idle 0
user 6597462958
usehostname
crtscts
modem
noipdefault
defaultroute
usepeerdns
persist

then execute ./pon provider

Here is the result for pon provider. Device could not connect to the
internet and i dont understand this outcome and error at all. Can you
help me about that.

Hi,

I am also trying to connect to TCELL 3G network. I installed pppd, kernel is already built with usb to serial module however could not configure pppd with correct chat scripts. Could you please explicitly tell me the locations of those modules.sh and chat.connect? This is extremely urgent for me.

Regards

Hello,

I’ve compiled ubuntu 12.04 kernel to my beaglebone by following the instructions (it comes with option module already selected):

git clone git://[github.com/RobertCNelson/linux-dev.git](http://github.com/RobertCNelson/linux-dev.git)
cd linux-dev
git checkout origin/am33x-v3.2 -b am33x-v3.2
./build_kernel.sh

from http://elinux.org/BeagleBoardUbuntu

You’ll need to download the linux-stable kernel from kernel.org repository: http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary

Att,

Fernando Akira Endo

Hi,

I’m trying to set pppd on my beaglebone black to use with a Telit GE864-GPS modem. I was able to set the connection but in the final step i get this messages on log file:

Serial connection established.

My /etc/ppp/peers/chat file is:

disconnect ‘/usr/sbin/chat -v -e -t 90 -f /etc/ppp/gprs-disconnect-chat’

and my /etc/ppp/options file:

Can anyone tell me if i’m doing something wrong?

Thanks
