Ok I’m getting much closer. I now actually get connected to the internet and getting an ip. However I seem to not be able to actually access it. Meaning that I can’t ping. Here is the output. Any help is appreciated.

PS. I also tried pinging 74.125.137.113 and it said pinging with 65 bytes and then just hung there until I CTRL c to get out.

I have made a little headway, but only a little. I have ppp setup and i am now getting a response, but it does not seem to be actually connecting to the internet as I don’t see any data usage on the sim card. It runs thru the process and then terminates the connection almost immediately. Here are the messages that I receive.

Can you point me in the right direction?

I am using the mtsmc-g2 connected to the SNAP Connect E10 http://www.synapse-wireless.com/e10. I do not seem to have the directories etc/ppp/options, or etc/ppp/peers/gsm. But When I type pppd in the command line I get [340601.690000] PPP generic driver version 2.4.2 and a bunch of garbled stuff. Is there something I need to do further with the ppp stuff first?

Thanx,

Hi Bryan,

I am still having trouble. Here is exactly what my code looks like. Can you please tell me what I am doing wrong? The error I get with this code is “socket.error: [Errno 101] Network is unreachable”

def postData(self, data, postURL, modemAPN):

self.ser.write('ATZ')

self.ser.write('AT+CGDCONT=1,"IP","'+modemAPN+'"')

time.sleep(1)

print self.ser.readline()

self.ser.write('ATD*99#')

self.ser.write('AT#GPRS=1')

print self.ser.readline()

time.sleep(10)

print 'waited 10 seconds'

print self.ser.readline()

self.ser.write('AT#GPRS=1')

print self.ser.readline()

conn = httplib.HTTPSConnection(postURL)

print conn

params = urllib.urlencode({'name': data, 'AnotherTextbox': 'anything'})

print params

headers = {"Content-type": "application/x-www-form-urlencoded"}

print headers

conn.request("POST", "/mapresources/sensorprocessing/processpost.aspx", params, headers )

response = conn.getresponse()

print response
