Q2406B and ADL_NO_GPRS_SERVICE

Legacy Legacy AirPrime modules
1

Hi,

I am working on a Q2406B. I have been trying to setup GPRS. Although I can succesfully subscribe to GPRS after +WIND:4 using

retVal = adl_gprsSubscribe ( GPRS_Handler );

I cannot setup GPRS by

setupReturn = adl_gprsSetup ( 1, SetupParams);

setupReturn is ADL_NO_GPRS_SERVICE.

===
Also when I use, at+cgclass? or at+cgclass=?, +CME ERROR: 3
is returned. I mean, I cannot change the GPRS class of the product.

===
AT+CGATT=1 also returns +CME Error : 3 (operation not allowed)

What could be the problem?

Best Regards,
Erdal

Hi Erdal,

you should check with your network provider if GPRS is allowed with the SIM card you use! Most likely the feature is not active or forbidden…

Thank you Jan,

I am convinced that my operator supports GPRS for my simcard, I checked with my cellphone.

There is a possibility that I am worried. During the firmware upgrade (from 6.50 to 6.55) GPRS feature of the product could have been disabled. Docs say ADL_NO_GPRS_SERVICE means GPRS service is not supported by the product. I found out a post that was posted by you (below link). How was the situation resolved? (by the way at+wcfm=2 (commercial feature management) returns 0000,0 which I guess means that no feature is activated.

Hello,

And you can also check your module, weather GPRS is enabled.
Issue ati3 command and see the end of the version number.

for example:
661_09gg… GPRS enabled
661_09gm… GPRS disabled

What a luck because with OS 6.61 we get a new function called “The Real Time Enhancement” feature. So part of the ADL apis are not usable without activation of that feature. Lots of administrative problems in the future…

The feature activation needs special code, so contact your distributor.

Hi,

Thanks for your reply. I checked and the result is 655_09gm.Q2406B 2015268 111705 17:01. Does this mean I have to upgrade the firmware, or do I need a password from my distributor and use the commercial feature AT command ?

Hello,

Firmware upgrade will not help (this settings are stored on a specific eeprom location) , i think your only option is to send the modules back to your distributor for gprs activation.

Best Regards,

Hi again,

I am afraid tomalex is right. There is a possibility of activation by AT command with a very long string that is tied to the module’s IMEI (so if no IMEI is set, you would need to set it first) and then get the command from your distributor… BUT: they don’t like to do that… it’s worth a try, but probably they won’t give it to you…

Best Regards,
Jan

Thanks guys,

I returned to my distributor and now waiting for an answer. He also sent me the preliminary Q24NG specs. Good news is that software and hardware compatibility with the previous versions looks to be given great care and the future looks promising.
