bt_gps & gsm_loc simple python app

[lda2000]

Hi Guys,

I've just put together two smaller Python apps I've seen around in this discussion board.

The resulting app prints 1) info obtained by a BT gps (i.e. $GPRMC sentence, but may change as you like) and 2) GSM cell id.

My wish is to collect these info periodically (i.e. 2/3 minutes) and send them back via an HTTP POST to a specified host.... could anybody help? ;-)

Thanks

-Luca

From (http://www.python.org/doc/current/li...-examples.html)

==
import httplib, urllib

# replace with whatever you want POSTed...
gps_coords = urllib.urlencode({'param_1': 'value_1', 'param_2': 'value_2'})

# form contents
headers = {"Content-type": "application/x-www-form-urlencoded", "Accept": "text/plain"}

conn = httplib.HTTPConnection("location-server.com:80")
conn.request("POST", "/cgi-bin/collect_loc", gps_coords, headers)
response = conn.getresponse()
data = response.read()
conn.close()
==

Both httplib and urllib are shipped with PyS60. Of course, you will have to create the CGI script separately.

Hi Sandeep,

Thanks a lot! I'll post my resulting work.

Bye.
