Hi Sebastian,

what model of the radio are you using?

Hi Neil,

Thank you very much. I fixed the problem. The problem was the space before /dev/ttyUSB0. Thanks a lot.

Hi Neil,

thank you very much for your reply. I removed the O_NDELAY flag and also removed the space after /dev/ttyUSB0 in the open command and am still getting the file description as -1. Is it because the port is already open? Is that a possibility? Is there any way to check that? Thanks again.

Best Regards,

JM

Hi,

I modified my program yet still not able to open the /dev/ttyUSB0 file. Here is a copy of the program:

# include <stdio.h>

# incluse <stdlib.h>

# include <unistd.h>

# include <getopt.h>

# include <errno.h>

# include <sys/types.h>

# include <sys/stat.h>

# include <fcntl.h>

# include <termios.h>

# include <string.h>

int main()

{

int fileptr;

fileptr = open (“/dev/ttyUSB0 “, O_RDWR | O_NOCTTY | O_NDELAY);

fnctl(fileptr, F_SETFL, 0);

printf(“Port has been successfully opened and the file description is %d “, fileptr);

close(fileptr);

return 0

}

The output I get when I run this program is:

Port has been successfully opened and the file description is -1.

If the file description is -1, the event of opening the file has failed. Is this correct?

I would very much appreciate it if someone could let me know the error in my program.

Best Regards,

Hi Jesse,

thank you very much for the reply. I wrote a small C program that would just open the ‘file’, ttyUSB0 and send out an SMS to a phone number using the AT commands. I am however getting a Segmentation fault when I try to open the file ttyUSB0 and write an AT command to it. Here is my program:

void main()

{

FILE *fileptr;

fileptr = fopen(” /dev/ttyUSB0 :,”a”);

puts(“AT!SSMS=0,xxxxxxxx,0,yyyyyyyyyy”); /* xxxxxxxxx is the phone number and yyyyyyyyy is the message */

fclose(fileptr);

}

I would appreciate it if you could let me know where my program went wrong. Thank you very much and have a great day.

Best Regards,

JM

Hi Jesse,

I have tried sending out and receiving sms by logging into minicom and using the AT prefix commands and the unit is working fine. I am trying to write a small application that accepts a message in the form of a text file (gedit) and sends an sms to a custom phone number also entered by the user. Since the sms-utils does not support the EV2 radio, can you suggest where to start looking, code/references, that I go through to get a basic idea how I could write my application? Thank you very much and have a great day.

Best Regards,

JM

Hi Jesse,

I copied the .smsconfig file using the scp to the device. I made sure it is in the /home/root directory on the device. I was still getting the same error so I connected to minicom and issued the AT command to make sure communication was present and I got an OK response. I could even voice call a phone number. Then I logged back in to the device and when I issued this command: sms send xxxxxxxx (where xxxxxxxxx was the phone number) I got this error: [ERROR] utils.c:device_lock:265: failed to create /var/lock/LCK..tty USB0: File exists, then I looked up the file LCK..tty USB0 using nano and it contained one line: 1578. I deleted this file and then from /var/temp again issued the command: sms send xxxxxxxx (where xxxxxxxxx was the phone number), I got the same error: [NOTICE] atcmd.c:atcmd_read:284: read timeout. I have copied the .smsconfig file for reference.

user:

baud-rate: 230400

smtp:

Any suggestions would be very much appreciated. Thank you very much.

Hi Jesse,

Thank you for the quick reply. I changed the device in the ${HOME}/.smsconfig to USB0, as the device I am working with is an MTCDP-EV2 model. I changed the revision number and then once again bitbaked the sms-utils. I am still getting the same error after having installed the package on the unit. Do I need to change anything else in the ${HOME}/.smsconfig file?

Thank you for your help. Have a great day.

Best Regards,

JM

Hi,

I have installed both packages, libesmtp and libyaml successfully and also managed to solve the errors I have been facing while installing the sms-utils package. I have now successfully installed the sms-utils package on the CDP unit. When I issue the command:

# sms-send xxxxxxxxxx

I am getting this error:

[NOTICE] atcmd.c:atcmd_read:284: read timeout

Any suggestions on how to solve this would be very much appreciated.

Best Regards,

JM

Thank you very much, Jesse. I have installed both packages ‘libesmtp’ and ‘libyaml’. I am manually installing the package by copying the ipk file to the unit and running opkg. After having bitbaked both libesmtp and libyaml from the terminal, I changed the revision number in the sms-utils.inc file and tried rebuilding the sms-utils package and yet I am getting the same error message. Does providing the ‘need dependency’ mean that I have to provide copies of libesmtp and libyaml in the same directory as ‘sms-utils’? Here is the sms-utils.inc file:

DESCRIPTION = “SMS Utilities”

HOMEPAGE = “http://www.multitech.net/&#8221;

SECTION = “console/utils”

PRIORITY = “optional”

LICENSE = “GPL”

DEPENDS = “libsmtp libyaml”

SRC_URI = “git://git.multitech.net/sms-utils.git;protocol=git;tag=${PV}”

S = “${WORKDIR}/git”

inherit autotools

PARLELL_MAKE = “”

Thank you very much and have a great day.

@Jesse Gilles, thank you very much for the quick reply. I shall indeed start a new topic for new questions in the future.

Thanks,

Hi,

I am trying to build a package using bitbake. In the file local.conf, what values do these three variables:

BBFILES = “” ; DISTRO = “” ;MACHINE = “” ; Need to contain? I would very much appreciate it if someone could answer my question. Thank you very much and have a great day.

I have recently purchased a Cellular Development Platform. I am using Ubuntu 10.0.04 for my OS. I am looking around for a good compatible USB to Serial port adapter. I would very much appreciate it if someone could let me know this information. Thank you very much.
