Hi all,
i use a CR1000 + SC105 + CS-GPRSmodem I try to setup a GPRS-callback communication with a remote station but I'm stuck :
The remote station cant reach my local server, so, I've asked my local operator to send me a capture of the configuration on the CR1000. There two wierd things :
-> IPTrace = 400
I don't understand this code, even with Loggernet's help...
-> The dialstring send stays on : AT+CGDCONT=1,"IP","orange.m2m" ;ATD*99***1#
That is my modem configuration string, used only in the initialization of the program. Then it's supposed to change in *99***1#, but the change doesn't happens.
Thank you in advance if you have a track of solution
Can you please explain how he captured the configuration of the CR1000. The est way of getting the full setup is to use our device configuration program and save the setup to a file which can be emailed.
Also can you also post a copy of your program which is changing the dialstring please.
Thank you for your answering,
He captured the configuration by using the Connect screen -> Station Status -> Status Table
I gave him this way, because it's easier to use than devconfig (for him).
Here is the configuration file obtained :

If I take the program above and load it into a logger here, the PPPDial response gets set to the basic string as you want.
However the status table shows the logger is not running the program above. I guess there is some difference between the program it is running and the code above?
The IPTrace setting indicates either deliberately or by accident the level of tracing (debug logs) that the logger would output has been set to 400 (there is help on this in the Device Configuration program for this setting). This would not cause the system to fail to connect unless perhaps the IPTrace COM port (a setting) is pointing to the same port as being used for the modem.
Set this value to 0 to disable it and in the logger settings check the IPTrace COM port is set to Inactive to avoid a conflict and to save a little power.
Yes, the difference is in the measurement code, I've deleted it to make it lighter for the forum. I can send you the full one.
For the re-setting of IPTrace, can I use the following command line in the CR1000 program: Setstatus("IPTrace",0)
Or should I do it with devconfig ?
Using Devconfig or Pakbus Graph is a more reliable way of doing it as you can also check the IPTrace Com port setting is inactive.
In your message you write "the PPPDial response gets set to the basic string as you want."
However, the problem is not the PPPDialResponse, it's the PPPDial.
Second point :
I have a second CR1000 with a CS-GPRS kit in my lab. I've tried to run the same program as the problematic station, it works. The GPRS communication works and it's pretty stable.
Then I wanted to know where is the difference between my two systems, that's why I asked him to send me a copy of the configuration. The differences are the two lines I've mentionned earlyer "pppDial" and "IPTrace"
There is also a little hardware difference :
The modem in my lab is a Maestro
The modem on site is a Sierra Wireless
Both are from a CS-GPRS kit.
Sorry I meaant PPPDial, after loading the program and running it on a logger with the same OS give this in the Status table after the program is loaded (no modem attached):
IPInfo: PPP IP: 0.0.0.0 PPP gw: 0.0.0.0 ppp state: program closing -> close success
TCPPort: 6785
pppInterface: 4
pppIPAddr: 0.0.0.0
pppUsername: orange
pppPassword: orange
pppDial: *99***1#
pppDialResponse: CONNECT
IPTrace: 0
I would check the program running in the logger is the one you intended. The current one is called: CPU:BT-SE1-2-0_27-02-13.CR1
As to the different modem names they are likely to be indentical internally. Sierra Wireless bought Wavecom and rebranded all the product range.
Anyway the model of modem does not change the pppDial setting which is a logger setting.
Ok, good new for the modem !
This is my entire program.

I loaded that exact code into a logger here, with the same operating system version, and when I restart the program the pppDial string is set as you expect. If I edit the string, then restart the program, the string is reset to "*99***1#" as expected.
Is there are chance that when you sent this program it was not accepted (perhaps due to a comms failure) or it was loaded without the run-now flag being set, such that an old variant of the program is still running? The program running in the logger has been running since 27th Feb.
It also works for me with the CR1000 in my lab, but not on site... That's the point.
Both systems are "hardwarely" almost similar, same program, different reaction. I think that the problem is in the configuration of the CR1000 on site. The fact is that I don't really know where to search in it.
There is also a little difference : the lab's CR1000 is on OS25, the one on site is on OS24.
My plan was to upload the OS26 on site once the communication works.
I don't think that the program is running since 27th Feb. That's the date of creation of the program, in the file name BT-SE-2-0_27_02_13.
The 11th line of the program status capture says :
StartTime : 4/25/2013 6:21:45 AM
Next week, I'll ask my colleague on site to erase the old programs and check the configuration with DevConfig.
I downgraded my logger to OS24 to match yours and cannot see the problem with it so the issue must be logger setup.
You are right the logger was restarted on the 25th April.
Unrelated to this setting and another possible problem: make sure the SC105 you are using has its RS232 port configured to run at 115200 baud to match the modem. The settings in the program cannot set that unfortunately. Normally for the GPRS package we set the SC105 to 115200 baud, but it could have reset somehow, or a new one could have been picked up from elsewhere - the default setting it 9600 baud.
Ok, I like your hypothesis about the SC105. But, if the SC105 is not set a at the good Baurate, would the red light blink ? The blink means that the device is "recorded" on a network.
The red light will flash on the modem if it registered on the network but even if it has nothing plugged into it. It is unaware of the baud rate set between it and the SC105.
Ok, I still can't go on site. What do you think of this solution :
I have a second SC105 in my lab which is correctly configured. I could mail to my operator on site and he could replace it. No ?
It would be worth a try.
