Messages that can appear include:

Message

Cause/Fault

ppp initialized

PPP was enabled and initialised OK

ppp program opening

PPPOpen in the program

ppp program closing

PPPClose in the program

ppp closing

Now trying to hang up the connection

ppp closed failed

Could not hang up the modem. Check the

modem/settings

ppp close success

ppp dialling

The datalogger is trying to dial

ppp dial connecting

The dial string was accepted. Waiting for a

Invalid dial string or service not available

ppp dialled

The PPP server has been dialled OK – a connect

message was received.

ppp opening

Starting negotiations with the PPP server

ppp authenticating

Sending the username password information

ppp authentication failed

Username/Password invalid for APN being used

ppp authenticated

Username/Password accept and OK

ppp up: ip xxx.xxx.xxx.xxx peer xxx.xxx.xxx.xxx

At the end of a call “ppp up:” should end up showing the same values as ppp ip:

and ppp gw:

Where "peer" should be the gateway.

For a successful connection the messages should follow a sequence such as

initialized, dialling, dial connecting, dialled, opening, authenticating, authenticated

and up. If the sequence stops along the way and reports a failed message this gives

an indication of the cause of the failure as shown in the table above.

If there is no dial string, or if the dial string is PPP, then dialling is

skipped and ppp “opening” should start up immediately.

If the PPP link works (i.e. you get a non-zero IP address in the screen above) but

you do not get a connection to Loggernet, check these points for calling out to

fixed IP addresses:

 That you are using the right IP and port setting in Loggernet to match

those assigned to you for the SIM.
