12 thoughts on “Sim Toolkit preventing network registration.”
HI
I am using the HE910-D. The issue I am having is that intermittently I
am getting unsolicited STN: 37 message while waiting for network
registration ( +CCREG: 1 ). After receiving the STN:37 no mater how long
I wait it will never become registered in the network.
I am not really sure what the #STN: 37 message means?
Also I have disable the SIM toolkit (AT#STIA=0 ) but this does not seem to help.
Any ideas?
the unsolicited indication #STN: 37: it means the SAT/USAT main menu is ready.
If you want to disable USAT function the procedure is:
AT#STIA=0
AT&W0
AT&P0
Restart the module. Only after the module is restarted, USAT is disable. But I do not recommend to do it. USAT can be used by the network operator to update the SIM info.
About your issue it is not clear what happens between AT+CPIN? and AT#SHDN. Do you wait for +CREG? unsolicited and without URCs you shutdown? What is the response of AT+CREG? AT+CGREG? AT+COPS? during these 2 minutes? It could help me to understand.
Hi Andrea,
Your right I was not save the settings and profile, after doing this I no longer received the unsolicited message STN: 37.
Thanks for the heads up, I had concerns about disabling.
While the modem is turn on I am setting AT+CGREG=1 to receive unsolicited network registration.
After AT+CPIN? the program is waiting to receive +CGREG: 1 or +CGREG: 5
to know that it’s registered. If it’s not registered after 2 minutes
then it’s shutdown and the power is turned off.
I have re-enabled the SIM toolkit and tried to get the responses that
you asked for but it’s an intermittent problem and I just can’t seem to
catch it. I think it might be related to changing the SIM toolkit mode
while it’s trying to be activated. By saving the settings and profile I
think I might be avoid it as it starts up with the same setting that are
being set with the initialisation commands.
Is there anyway to force the modem to retry network registration? Maybe I could do this if it times out waiting for +CGREG: 1.
Thanks
Ryan
Hi Ryan,
what is strange is that you don’t get any status change for+CREG and +CGREG, at least o indicate that the module is searching for an available network (+CREG: 2).
In case, if no URCs are received I could suggest to try with AT+COPS=0 (it restart the automatic selection) or AT+COPS=? to verify which are the available operators and AT+COPS=1 for manual selection.
Hi Andrea,
I am having trouble turn off unsolicited toolkit messages AT#STIA=1. I
am now sending AT&W0 and AT&P0 but after a restart the setting
has not changed?
The list of command below will run each time the modem performs an
upload, is there any problem with saving non-volatile data each time the
modem is used? Is there a limited number of writes?
Because I cant be sure what settings have been applied in the modem I
always set the modem to defaults with AT&F1 then apply the
settings I need each time, Is this a valid thing to do? would it be
causing any problems?
can you check AT#STIA? response before the module is shutdown?
How many modules do you have behaving in the same way? Can you reflash this module with the same firmware and remove AT#STIA=1, AT&W0, AT&P0 to verify that SIM toolkit is correctly started but with URC disabled?

Hi Andrea.
Tested a few new modems stright out of that box, all reported
The modems are shipped with 12.00.32, I only have 12.00.2, so i upgraded one of the modules and it still reported mode 2.
at OK AT+CGMR 12.00.024
OK AT#STIA? #STIA: 1,2,1,ffffffff7f9d00ffff00001f2200000003c9
OK
How should I set the modems back to factory settings, AT&F1 dose not seem to be doing it?
ok I probably understood what is the issue. Can you check if AT#ENS? returns #ENS: 1 ?
In this case the HE910-D you bought, have a special configuration for AT&T provider.
If you can copy here a couple of IMEIs I can double check.
Anyway, do you have to use your applications in US with AT&T?
With AT#ENS=1 set the AT#STIA <mode> is automatically set to 2 with URCs enabled.
If you don’t need AT&T configuration you can set AT#ENS=0, This is automatically stored in NVM and at next power cycle the #STN URCs will be disable.
Hi Andrea,
Yes the modules have ENS set to 1.
IMEI:351579051658852
IMEI:351579051736369
Yes some of our users have AT&T as there provider, other will use verizon and sprint.
We use optus and telstra in Australia.
Is there any problem using ENS=1 when connecting to other providers? Do diffrent provders require diffrent settings?
Hi Andrea,
Still waiting your response..and it would be great to get some feedback on the command sequence we are using. information you have provided retrying the network registration and saving profile settings has been useful.
Thanks
Ryan
Hi Ryan,
I apologize for the late reply. I confirm you the modules you have, have special AT&T configuration. Normally it is not an issue to keep AT#ENS=1 with other providers, anyway if you want to disable this setting which include also AT#STIA=2, it is ok, just keep it for AT&T.

Hi Ryan,
there is something I don’t understand in all this
story. The SIM Toolkit default settings of HE910-D is AT#STIA=1 as
reported in the AT command guide:
1 – enable SAT without unsolicited indication #STN (default)
In fact starting from a new and fresh module the answer is:
at#stia?
#STIA: 1,1,2,ffffffff7f9d00ffff00001f2200000003c9
OK
Therefore you wouldn’t have to change the #STIA settings since URCs shouldn’t be displayed.
This
is the strange part since, from the beginning you said that #STN: 37
came out from the serial port, i.e. AT#STIA=2 was already set.
After you have sent the sequence
[Data A] 09/29/14 11:46:30 AT#STIA=1CR

can you check AT#STIA? response before the module is shutdown?
How many modules do you have behaving in the same way? Can you reflash this module with the same firmware and remove AT#STIA=1, AT&W0, AT&P0 to verify that SIM toolkit is correctly started but with URC disabled?

Hi Andrea.
Tested a few new modems stright out of that box, all reported
AT#STIA?
#STIA: 1,2,1,ffffffff7f9d00ffff00001f2200000003c9
The modems are shipped with 12.00.32, I only have 12.00.2, so i upgraded one of the modules and it still reported mode 2.
at
OK
AT+CGMR
12.00.024
OK
AT#STIA?
#STIA: 1,2,1,ffffffff7f9d00ffff00001f2200000003c9
OK
How should I set the modems back to factory settings, AT&F1 dose not seem to be doing it?
ok I probably understood what is the issue. Can you check if AT#ENS? returns #ENS: 1 ?
In this case the HE910-D you bought, have a special configuration for AT&T provider.
If you can copy here a couple of IMEIs I can double check.
Anyway, do you have to use your applications in US with AT&T?
With AT#ENS=1 set the AT#STIA <mode> is automatically set to 2 with URCs enabled.
If you don’t need AT&T configuration you can set AT#ENS=0, This is automatically stored in NVM and at next power cycle the #STN URCs will be disable.
Hi Andrea,
Yes the modules have ENS set to 1.
IMEI:351579051658852
IMEI:351579051736369
Yes some of our users have AT&T as there provider, other will use verizon and sprint.
We use optus and telstra in Australia.
Is there any problem using ENS=1 when connecting to other providers? Do diffrent provders require diffrent settings?
Hi Andrea,
Still waiting your response..and it would be great to get some feedback on the command sequence we are using. information you have provided retrying the network registration and saving profile settings has been useful.
Thanks
Ryan
Hi Ryan,
I apologize for the late reply. I confirm you the modules you have, have special AT&T configuration. Normally it is not an issue to keep AT#ENS=1 with other providers, anyway if you want to disable this setting which include also AT#STIA=2, it is ok, just keep it for AT&T.
