3G Modem interface with AM3358 EVM

Other Parts Discussed in Thread: AM3358, TMDXEVM3358

HI, I have been working on AM3358 EVM board and want to interface with a 3G modem so that i can send/receive the data to a particular server.

There is no inbuilt 3G modem within the board and i just connect that additionally. Hence could anyone provide me the following details:

1) Which kind of 3G modems can be attached to the board?

2) What are the software/device driver programs available for interface?

3) How does the data transfer from EVM board to server after attaching the 3G modem?

Thanks in advance

Regards,

Nitin

    Moreover pls provide me any link/information about the code for CAN interface in AM338 board.

    If the board is supposed to receive/send some data from CAN port , how can we write driver codes for it?

    Hello Nitin

    Are you talking about a USB 3G modem or serial 3G modem? For serial, I believe the connection and further use is straightforward, just connect the cable and use ppp/pppd, wvdial or any other dial up program available for linux.

    For USB modems, you may have issues related to drivers and device detection (udev). lsusb can help to tell the "kernel´s first impression" about your modem.

    While it is easy to add new rules to udev in order to properly detect your modem, I think TI guys could help here with info about what was included in the current AM335x kernel.

    Cheers

    Thank for your comments Marcelo.

    Could you please some links in support of your answer.

    Would be much prolific, if you share any information about driver codes?

    Hello Nitin

    In PC, people are used to run usb-modeswitch [1] to solve udev rules and modem initialization for each (USB) modem manufacturer. A good starting point is to search about "usb-modeswitch" and "beaglebone" or "beagleboard". For instance:

    http://www.draisberghof.de/usb_modeswitch/bb/viewtopic.php?t=642&sid=02dad365d9222659e337627f557bfed8

    http://lakm.us/logit/2012/01/compile-usb-serial-modem-using-option-c-ubuntu-on-beagleboard-xm/

    For serial is even easier to find good stuff on the internet just looking for "ppp tutorial linux". Add beagleboard or beaglebone for more specific results.

    http://axion.physics.ubc.ca/ppp-linux.html

    I did not have time to check what was bundled in default AM335x kernel and it is possible do not have the ppp support enabled. Please, use menuconfig to check these options.

    Hi Marcelo, Hope you are fine.

    I just got a Huawei E303 USB modem and want it to connect to the TMDXEVM3358 board to use the internet services. Can you tel me the steps required to execute this process?

     

    Thanks :)
