Comment on SMS over 3G and Bluetooth from Python by David Faure

Excellent stuff, exactly what I was looking for.

Please note that the blog software replaced all quotes and double-quotes with non-ascii characters, which python doesn’t like (and the indenting got messed up too). It would probably be helpful to provide a link to a plain-text version of it for proper download rather than copy/paste/reformatting by hand

Also the “if data.find(’+cmgl’)>0:” seems wrong, here it’s +CMGL in uppercase, and it’s at offset 0, and anyway the text of the SMS is on the following lines. So I recommend the following while loop instead:

while data != ”:
data = self.ser.readline()
if data.find(‘+CMGL’)>=0:
print·
print string.rstrip(data)

I was wondering about writing a GUI app to do this. But maybe it would be simpler to just improve the python script so that it sends an email for each SMS it sees in GetAllSMS, so that one can get his incoming SMS messages in his email client, no need to monitor yet another application.

Comment on Steganography in Python by Carlos

Hi,

You are wrong.
Stepic doesn’t work for JPEG files(http://domnit.org/blog/2007/02.html).
The reason: JPEG are not lossles format.
Your program runs because you use the same variable to decode (without read the file another time). If you don’t beleave me, try this:
import Image
import stepic
im = Image.open(’in.jpg’)
s = stepic.Steganographer(im)
im2 = s.encode(’This is some cool text’)
im2.save(’out.jpg’,’JPEG’)
im3 = Image.open(’out.jpg’)
s = stepic.decode(im3)
data = s.decode()
print data

Is it the same with the Sony Ericson K550i AT commands? I am thinking of using it for our thesis. thanks for the post..

Comment on SMS over 3G and Bluetooth from Python by Myke

Hi, I’m new with python about 3 days old using the program. I was wondering how I can create an application that will detect all BT device within range and allow it to send a file(a command maybe) and for the system to send message to them. I was able to do the detect but having hard time sending and receiving. Does a code require a specific modem to work? or it can work using any BT device?

If you have a guide or a working sample that would be very helpfull

Thanks,
Myke

I have HUAWEI E156G modem. Everything works perfectly, same us with E220, but ~ for 15 minutes. Then modem just disconnects (hangs), and gets up on another USB address after several seconds.

Tried different hardware, different kernels and distros – same result. E220, E176 works perfectly.

Maybe anyone found solution?
