Hi

I am trying to get GSM module connected to beagle bone black.

If any one has done it previously please pen down procedure for the same.

I have slight know how, that I have to get ppp daemon running, configure may be wvdial for this purpose.

Any document/sample code link will be of great help.

Hi

Just an observation, I have telit module If I connect this module via usb serial converter on my ubuntu laptop I get an interface as

ttyUSB0 in ubuntu machine.

But when I do the same in beaglebone the usb device get registered but I do not get anything on the serial port.

Anything which I might be missing.

HI Abhilash

I did lsusb I see usb to serial converter getting detected.

Now I want to configure gsm module by sending messages via usb to gsm module.

When I do this on ubuntu lappy it gets detected i get ttyUSB0 but not on beagle board.

Tested the GSM module on my system usinig AT commands they work fine.

Hi Anuj,

Could you please verify if the USB to serial converter is working properly with BB by connecting TX to Rx and see if you are getting data back?

If that works fine then you need to configure your serial port for proper configuration as expected by the module and then send various commands.

Hope it helped..

Regards

Or you mean to say /Dev/tty* for this device is not getting created at all? What does dmesg say?

Hi

You can connect UART from bbb to gsm module if it is 3.3v ttl .

Are you using minicom in bbb?

Try shorting tx and rx in usb serial converter and check if you getting echo .

Check for which is the driver being used for the GSM modem on your Ubuntu system. That driver may not be available on BBB. If it is there, try loading it manually.

The cp210x driver might be missing from the BBB. Copy & load the cross compiled one onto BBB - you may get the ttyUSB0.

Hello Anil

I cross compiled the driver for bbb.

cp210x.ko: ELF 32-bit LSB relocatable, ARM, EABI5 version 1 (SYSV), BuildID[sha1]=caecd9e3cc097e52a24adcdee04ae8ecc9f5dd04, not stripped

Now when I am trying to insert the module I am getting invalid module format.

I am getting the following error.

insmod /lib/modules/4.1.6/kernel/drivers/usb/cp210x.ko

[ 184.801499] cp210x: disagrees about version of symbol module_layout

insmod: can't insert '/lib/modules/4.1.6/kernel/drivers/usb/cp210x.ko': invalid module format

This is related with the kernel version which is used for compiling the code.

But I am using the 4.1.1 kernel currently and cross compiled the code for that only.

Apart from the kernel version, your kernel config also should be same.

For building drivers, we use the kernel headers & .config - the .config should be matching the one used to build the running kernel. Otherwise, if you don't have that, you can build a kernel image with the current .config and replace the kernel image on the BBB.
