Using BlackBarry Bold 9000 as 3G modem on Linux

Recently I got the BlackBerry Bold 9000 and it can work as 3G modem by using the BlackBerry Desktop Software. Since I used to work under the environment of Linux, I want to make it work on Linux.

In ubuntu 9.10, I do the following steps

$ sudo apt-get install pkg-config libusb-dev libssl-dev libboost-serialization-dev libtar-dev libgtkmm-2.4-dev libglibmm-2.4-dev libglademm-2.4-dev zlib1g-dev

And then download and install the "libbarry" and "barry-util" from Source Forge: http://sourceforge.net/projects/barry/files/

But it could not work.

After trial for awhile, I finally make it works from the recompiling and debug from the ppp package.

In the debugging, I found that it looks when using the IPCP to get the local IP adderss, BlackBerry cannot provide it immediately and pppd daemon polling for many times, so that ppp get the many NAK's from Barry. Finally it provides but the pppd complains and exit.

The quickfix to it is to increase the max number of IPCP NAK tolerance to reject the NAK's information. From the the ppp source tree:

vi pppd/ipcp.c

and the line:

f->maxnakloops = 100;

and change it to larger number, I use the 2000;

And it works well,

Also, my telecom company is Taiwan Mobile, attach the ppp script and chat for reference:

/etc/ppp/peers/barry-taiwan_mobile:

-------------

pty "/usr/sbin/pppob"

connect "/usr/sbin/chat -f /etc/chatscripts/barry-taiwan_mobile.chat"

#noauth

/etc/chatscripts/barry-taiwan_mobile.chat:

------------

ABORT ERROR

OK ATZ

OK ATI

OK AT+CGDCONT=1,"IP","internet"

The workable command is:

pppd call barry-taiwan_mobile
