Re: is it possible to send a text with alarmed?
 
first of all thats a great idea, because we can use this for holidays, for example i would like my phone to send a message to all my contacts saying 'merry xmas' 25 december, or happy new year or.....without having to send it manually .
if there was a way to send messages via xterm than i think that should be possible.

Yes, I have a script that does it

In Alarmed:
Select "Command execution" and put this command

This code was tokem from vertsms app.
Maybe it contains unused functions, but it works

Re: is it possible to send a text with alarmed?
 
cool man,can u supply it wil simple instructions?

CepiPerez 2010-09-22 21:59
Re: is it possible to send a text with alarmed?
 
Edited #3
Make shure sendsms.py has exec permissions
chmod +x /path/to/sendsms.py

thesnake505 2010-09-22 22:05
Re: is it possible to send a text with alarmed?
 
so i save the script in a file called sendsms.py

save say in my docs so

chmod +x/MyDocs/sendsms.py in alarmed? sorry am a bit of noob!

CepiPerez 2010-09-22 22:08
Re: is it possible to send a text with alarmed?
 
Nop.
Save the file in MyDocs
Then open x-term and type:
chmod +x /home/user/MyDocs/sendsms.py

If you want to try if the script works then in x-term type
/home/user/MyDocs/sendsms.py YOURNUMBER "Test message"

If you receive a message from yourself then it works

thesnake505 2010-09-22 22:19
Re: is it possible to send a text with alarmed?
 
ahh cool man, i got ya, next question

i saved the file (am at work using n900) and its saved as sendsms.py.text, how do i remove the txt from the name?

CepiPerez 2010-09-22 22:31
Re: is it possible to send a text with alarmed?
 
in x-term:
mv /home/user/MyDocs/sendsms.py.txt /home/user/MyDocs/sendsms.py

thesnake505 2010-09-22 22:56
Re: is it possible to send a text with alarmed?
 
ok getting some were i think, other then i now get this

/home/user # /home/user/MyDocs/sendsms.py 07********* "hay"
/bin/sh: /home/user/MyDocs/sendsms.py: Permission denied
/home/user #

CepiPerez 2010-09-22 23:21
Re: is it possible to send a text with alarmed?
 
in x-term:
sudo gainroot
chmod +x /home/user/MyDocs/sendsms.py
chown user:users /home/user/MyDocs/sendsms.py

Mydocs is a stupid FAT partition. chmod and chown do not work.

/home/user is a better place for this. Maybe /home/use/bin or /home/user/scripts. (May need to create.)

Yes I forgot that
I have all my scripts in /home/user/scripts

Re: is it possible to send a text with alarmed?
 
I tried not to run it gives errors.

The problem is that not send any sms, because recipients do not receive them.

Any ideas?

theonelaw 2011-01-16 10:23
Re: is it possible to send a text with alarmed?
 
Put in /usr/local/sbin
chmod to 755
in xterm:

/usr/local/sbin/sendsms.py 08numeric**** "message"

works for me. thanks all

"sendsms.py" I have never worked

Re: is it possible to send a text with alarmed?
 
in xterm when i try to run it, its saying no such file or directory, this is how i ran it,

Went to the location of sendsms.py (/home/user/SendSchedSMS/)and typed the following

./sendsms.py numericnumber "Message"

No Such File or Directory is what i get

Need to move it off /home/user because that is a FAT partition,
best stick it in /usr/sbin maybe, and chmod 755

Someone else may have a better solution,
but that works for me.

Even now i am getting the same message... that no such file or directory.

is the syntax right?

./sendsms.py <number> <message inside quotes>

someone help!!!

Which directory is it in ?

should run it like this:

/usr/local/sbin/sendsms.py <number> <message inside quotes>

or
/whatever/directory/you-put-it-in/sendsms.py <number> <message inside quotes>


DId you chmod it to be executable?

Re: is it possible to send a text with alarmed?
 
Hi,

I've tried the script. While it does run, it doesn't seem to send an sms.

I've combined this script and the old script (pymaemosms or some such) into a script that shows some more debug info.
When running it, it completes, but my sms doesn't show up (number formatted as +<countrycode><phonenumber>.
Anyone knows what's going on or how I can troubleshoot some more? (You can use the --verbose argument to show some more details).

Sending SMS Using Python Dbus:

I used the following links for reference:
1. http://www.dreamfabric.com/sms/
2. http://www.exothermia.net/monkeys_and_robots/2009/04/24/python-code-to-decode-sms-pdu/

5. https://garage.maemo.org/plugins/wiki/index.php?CSD%20programming%20information&id=1106&type=g

Additional Notes:
1. Use the dbus-monitor to see dbus communication. Follow link #4 above on how to see the dbus CSD communication log.
2. The phone number is expected to be in semi-octets
3. Each character in the message should be represented as an octet. Refer to this http://www.dreamfabric.com/sms/hello.html link on how to convert a message to octets

Seems it does work if you don't use +<countrycode> as a prefix...

Interesting, wonder whether that depends on your cellular operator or whether the script can be improved?!?!?

should run it like this:

or
/whatever/directory/you-put-it-in/sendsms.py <number> <message inside quotes>


DId you chmod it to be executable?
yes i did the same. i even did chmod 777, still getting the same issue

Assumption on my part, the usual mistake:
Perhaps you need python which I got long ago by installing something
that had a dependency on python.

Am checking now, but I think I got it when I was working on advanced-clock-plugin.

do you have a directory /usr/share/python ?
if you do, then it is probably something else missing

Anyone knows what's going on or how I can troubleshoot some more? (You can use the --verbose argument to show some more details).

Apparently this script required Python 2.5+.
