Hi,

I would like to use GSM with BB.
I've searched and found this http://www.sparkfun.com/products/9427
However, I'm a hardware noob and do not know how to connect the
evaluation board with BB.
Any information is appreciated.

Thanks.

Thanks.

this modules can connect over usb (using usb2serial) or a
direct serial connection. Both should be possible to use
on a BB.

What do you want to do with GSM ? If it can face your needs, you can use Huawei 3G modems that contain a SIM Card . But I do not know your idea

Wait... so I'm supposed to connect the evaluation board to the pc via
usb2serial?
Then BB also connected to the pc which acts as the middleman?

I wanted to try making phone calls from BB and I was already given the
evaluation board.
Thanks for introducing me to Huawei though.

Oh and the evaluation board only have a mini usb port not a normal
one.

nope.

the BB has a USB host, so you can connect it directly to the BB

BB with usb A host -> usb cable -> GSM module with USB mini-B

Sorry what are the modules to be built for it?
Thanks a lot of your help.

Ok I've built FTDI driver but once Android is booted up the board
stops lighting up.

The board is recognized when I plug it in but I'll get simcard error
when I try to change call setting.
Are there any other modules that I need to build or modifications to
be made?

Hi,

May be this helps !

There are certain GSM modems that come along with the serial interface and also they come along with a command set called the AT commands .
http://www.olimex.com/dev/pdf/AVR/AVR-GSM/SIM300DATC.pdf

All one has to do is to pass this commands from the serial port (A host can be a microcontroller , A hyperterminal Program on a PC …etc) to these modems

For experimentation you could find modules that have a simcomm 300 module as they are generally cheaper !

So if you can get some read/Write operations through the serial port on the beagle then you can hook them up to the GSM modem to send an SMS, call …etc

Thanks,
