Randomly SMS sent passes or fails

Randomly SMS sent passes or fails

[Viallard Anthony]

Hello,

I've a weird issue. I don't know what's going on...

I try to send SMS with a T-mobile SIM card in Germany. The SIM card 
doesn't require PIN code. I can get the GSM network and I don't use GPRS.

Sometimes, I can send SMS, and another time, It fails. More precisely, 
when I've got an ofono which can send SMS, I can send all the SMS I 
want, it works. But if I restart ofono, either it works or not.

I added OFONO_AT_DEBUG=1 in my env, and tried to find some troubles in 
the logs. I've got some errors but I don't think they are criticals and
anyway, they appeared when SMS working too :

-------------------------------
 > AT+CPINR\r
< \r\nERROR\r\n
Querying remaining pin retries failed

[...]

Provisioning failed
-------------------------------

I can see some differences in time for "AT+CRSM" commands but, they are 
in the same order. And, after many tests, I don't think the problem is here.

And, when the SMS send fails, the modem tells me :

-------------------------------
CMS ERROR: Unknown error\r\n

-------------------------------

Not very useful....

Also,@same time, I tested in Switzerland with SwissCom and I don't 
have problem.

1 month ago, it worked well. I don't get it...

I've got a "SIMCOM_SIM5216E" modem. Using the driver g1 or the new 
simcom driver I developped, with ofono 1.6 or 1.12, it's the same behavior.

Maybe have you already see this kind of things ? My brain is lost.

Regards,
avd.

This is not supported by all modems, it is a generic 27.007 command for 
pin retry counts.  However it was added in a fairly late version of the 
spec, so not many devices support this.

This should not affect anything, unless your operator requires SMS to be 
sent over GPRS.

Nope, can't really help here; perhaps if you shared a detailed AT log?

I tried to find some information about the operator and SMS/GPRS. I 
didn't find documentation in my fluent language. I will ask to a german 
guy. Maybe, there are a AT command to know wether operator supports this ?

Otherwise, I try to find documentation about this amazing SMS over GPRS 
feature. From what I read, there an AT command to select the behavior. I 
guess it's the AT+CGSMS command. Ofono set CGSMS to 3 :

AT+CGSMS=3

 From the modem documentation, I see :

A numeric parameter which indicates the service or service preference to 
be used
0 – GPRS(value is not really supported and is internally mapped to 2)
1 – circuit switched(value is not really supported and is internally 
mapped to 3)
2 – GPRS preferred (use circuit switched if GPRS not available)
3 – circuit switched preferred (use GPRS if circuit switched not available)

Maybe the "circuit switched" has got some troubles on the operator 
network and as I disabled GPRS, the SMS sending failed most of the time ?

There also the command AT+CSMS :

+CSMS: 1,1,1

The first 1 tells the "SMS@command is compatible with GSM phase 2+.". 
Perhaps, the thing has an impact about the issue ...

avd.

Any comments ? :(

Before, I tested with 1.6.

And, today, I tried with 1.12.

And, I've got some troubles at modem power up... During the 3 first 
start, ofono was blocked after sending a command. Here 2 pastes :

------------------------------

00, 0
ofonod[10387]: Data: > AT+CMGF=?\r
------------------------------

As you can see, It's not always at the same moment. After that, I can't 
send AT command anymore, the modem seems to be locked.

I try to debug this and found the CMUX and CMUXSRVPORT ports. I can have 
a DIAG port, so, I try to configure it. I stopped ofono, the modem and 
sent these commands :

------------------------------
AT+CMUXSRVPORT=0, 0
AT+CMUXSRVPORT=1, 5
AT+CMUXSRVPORT=2, 1
AT+CMUXSRVPORT=3, 1

+CMUX=0
------------------------------

------------------------------
AT+CMUXSRVPORT
--------------
< port >: virtual com port
0 – 3 currently support 4 virtual com ports index from 0 to 3

< service >: valid service
0 – DIAG Service
1 – DATA(MODEM) Service
5 – NMEA Service
------------------------------

And now, each time I start ofono and power up the modem, it works. No 
lock. Hum, I'm disapointed. I didn't think theses commands could fix the 
problem. And, no messages in diag or NMEA tty. Hum... And moreover, now 
all SMS I send are received. No failure. So good news, but, I'm troubled.

After grepping on ofono source, I see some driver plugins do a CMUX set 
(calipso, phonesim). Maybe, I need to execute a CMUX set ??? It can be 
important ?

Nevertheless, I don't understand why I have problems with this T-Mobile 
SIM card and not with Vodafone for example...

Regards,
Anthony.

CMUX is used on devices with 1 physical serial port.  It is used to 
enter into so-called Multiplexing mode, a binary protocol that runs 
multiple logical AT ports over a single physical port.  Refer to 3GPP 
27.010.  I do not know whether your hardware supports multiplexing or 
not.  If the modem is detected with multiple serial ports, then likely 
it does not require messing with CMUX.

I found the issue !

On our embedded platform, there a CPLD which drive the reset, the power 
and the flight mode of the GSM chips.

And, guess what ? There has been an update of the CPLD sometime ago. And 
this update enables always the flight mode ... !!!

So that, depending of the board I used, the version for the CPLD was 
different (not all my boards were updated), sometimes I could send SMS, 
sometimes not, sometimes the GSM modem was blocked, ...

An update of CPLD code fix the problem !

Sorry for the noise :)

It's time to take a tea and be happy.

Hi,

I try to find how i can fix the "provisioning failed" message.

Actually, I have always troubles with T-Mobile. I think I need to fix 
this provisioning issue. How can I do this ? I tried to see where this 
provisioning in the source code but I was quickly lost.

Bellow, you could see some troubles I have.

scenario:
  * enable modem power ;
  * enter pin code ;
  * set APN ;
  * and tried to enable GPRS.

First, there are no answer from modem about "AT+COPS=3,2" command.

And next, the "+CGEV: ME DETACH" disturb me. In the documentation of the 
SIMCOM module, I see :

"The mobile equipment has forced a Packet Domain detach. This implies 
that all active contexts have been deactivated. These are not reported 
separately."

I tried to re-attach with "Active" command but it fails :

------------------------------------------------------------------

In ConnectionManager, I see the "Attached" variable is "False".

Can you help me ?

Is the modem auto-attaching to GPRS by default?  You might want to turn 
off that behavior if posible.

That is the result of AT+CGATT=0 command.

Try toggling the ConnectionManager Powered property off and then on.

I think I've found where the issue is. The MCC and MNC can't be 
retrieve. And the cause is the mnc length can't be retrieve in this 
callback:

static void sim_ad_read_cb(int ok, int length, int record,
				const unsigned char *data,
				int record_length, void *userdata)

The call returns at the test "if (!ok)". So, mnt_length stay at 0 and 
next, on IMSI callback, as it doesn't know mnc_length, it doesn't 
extract MCC and MNC.

I don't know why ofono call the callback with ok=0. In the log, I see 
the command was successful:

---------------
Mar 28 13:50:05 mr3000 ofonod[6859]: Data: > AT+CRSM=192,28589\r
Mar 28 13:50:05 mr3000 ofonod[6859]: Data: < \r\n+CRSM: 
144,0,""\r\n\r\nOK\r\n
---------------

Maybe a clue on my problem... Why ofono says the command failed ?

Anthony.

Errr, ok :P

How do you known this ? I looked on AT documentation for my modem, on 
3GPP TS 27.007 V3.13.0, I saw nothing...

I added some logs and each time ofono does AT+CRSM commands, there a 
call to "sim_fs_op_error" function ...

I've got two kind of answers on AT+CRSM commands :


ofonod[12357]: Data: < \r\n+CRSM: 106,130,""\r\n\r\nOK\r\n

or

ofonod[6859]: Data: < \r\n+CRSM: 144,0,""\r\n\r\nOK\r\n

It means all the CRSM commands fails ???

Anthony.

You really do not want to know.  But if you do, see 3GPP 51.011 or ETSI 
102.221 for details.

I'm guessing you have a 3G sim.  Refer to 'Table 10.14: Status byte 
coding - wrong parameters' in ETSI 102.221.  Literally 106 means '6A', 
130 means '82' -> File Not Found.

Actually, this is peculiar, the CRSM command is not failing and the 
result is fine.  Just that it is empty.  Perhaps you need to quirk the 
CRSM behavior in this case.  Does adding your modem to the list in 
at_sim_read_info()

                 /* Maximum possible length */
                 len += sprintf(buf + len, ",0,0,255");
                 break;

make it work properly?

I added the quirk as above and Yes ! I've got values now:

ofonod[11230]: Data: > AT+CRSM=178,28614,1,4,8\r
ofonod[11230]: Data: < \r\n+CRSM: 144,0,"62F2100000FFFE01"\r\n\r\nOK\r\n

-------------------------------------

and SMS work ! Actually, It works if GPRS isn't Active... If I enable 
GPRS, It fails with message CMS ERROR: 500 (Unknown error):

-------------------------------------

-------------------------------------

So, I guess when I enable GPRS, my GSM module wants to send SMS over 
GPRS... And maybe, I can't because ofono always fails on provisioning:

-------------------------------------
ofonod[7135]: src/gprs-provision.c:__ofono_gprs_provision_get_settings()

ofonod[7135]: 
/usr/share/mobile-broadband-provider-info/serviceproviders.xml:1562 
Duplicate context detected
ofonod[7135]: Provisioning failed
-------------------------------------

I read the source code which can explain the issue. I guess the problem 
isn't really a problem. There 2 apn tags in serviceproviders.xml for 
T-Mobile. This is why I've got "Duplicate context detected" message.

As I understand, the provision plugin wants only 1 apn (allow_duplicates 
is FALSE) by MCC/MNC. Why ? There are many others operators (according 
to serviceproviders.xml) who have more than 1 apn. So, for these, the 
provisioning always fails ?

Maybe I must write an another provision plugin which supports multiples 
apn entries ? It's tricky to implement this ?

Anthony.

I doubt provisioning has anything to do with this.  That is only for

This is automatic provisioning.  If there are multiple possibilities 
that fit, then this requires user input.  Obviously oFono does not 
support user input, so a UI of some sort to finish provisioning is required.

You can certainly do this, however you still need to know which context 
to activate.

Indeed, I tried to remove duplicate entries, provisioning is good but 
SMS fail with GPRS enabled.

I see stange behavior too. When I try to re-enabled a disabled GPRS

issue to see what happenning in the source code.

Hi denis and ofono guys,

I'm still searching why I've issues on SMS with SIM5216 GSM module and 
T-Mobile.

What did you mean by auto-attaching to GPRS by default ?

To bring GPRS up, I configure it and I call 
ConnectionContext.SetProperty with Active=1 and then, I've got GPRS.

I dig out this old answer because I searched why in ConnectionManager 
I've got Bearer: "none". Then, I've found a place (in gprs_initialized() 
function) where ofono try to get data bearer. By default, ofono uses 
"AT+CPSB=1" and a callback on "+CPSB:" reply.

There haven't "AT+CPSB" command for SIM5216. I thought I needed to add a 
quirk like Telit or Huawai. I searched on internet and found an old 
message from this list ("[PATCH 6/8] gprs: data bearer for telit with 
PSNT") where you, Denis, answer to Christopher Vogl about the data 
bearer quirk which made for telit and wonder :

"Do you really need to query this?  In theory if we are turning off
auto-attach, we should never be in a state where the bearer should be
queried."

So, I don't know if I must add a quirk (there AT+CNSMOD command for 
SIM5216). What does auto-attach mean ?

Anthony Viallard.

Hi everyone,

I'm still working on this subject. I analyzed ofono logs to see if there 
are troubles.

I still don't understand what do you mean by auto-attaching. Where can I 
see this ? in an AT command return ? viewing AT command sent ?

So, I added AT+CNSMOD simcom quirk... I don't know if it mandatory. This 
bearer is required to do right stuff ?


Otherwise, I see weird things in logs:

  * some AT+CRSM requests (READ RECORD) return "FFFFF..." :

------------
ofonod[11230]: Data: < \r\n+CRSM: 144,0,"FFFFFFFFFFFFFFFF"\r\n\r\nOK\r\n
------------

Is it normal ? For example, on EFmsisdn (6F40), the first AT command is 
a "GET RESPONSE" and next, ofono does a "READ RECORD". And this "READ 
RECORD" returns FFFFF.... whereas "GET RESPONSE" returns pretty good data" :

------------
ofonod[11230]: Data: > AT+CRSM=192,28480,0,0,255\r
ofonod[11230]: Data: < \r\n+CRSM: 
144,0,"6221182050221001E0483026F40A5038001718A01058B036F060B800200788800F10100"\r\n\r\nOK\r\n
ofonod[11230]: drivers/atmodem/sim.c:at_crsm_info_cb() crsm_info_cb: 90, 
00, 35
ofonod[11230]: Data: > AT+CRSM=178,28480,1,4,30\r
ofonod[11230]: Data: < \r\n+CRSM: 
144,0,"FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF"\r\n\r\nOK\r\n
ofonod[11230]: drivers/atmodem/sim.c:at_crsm_read_cb() crsm_read_cb: 90, 
00, 30
------------

  * Some SIM files aren't found. On this T-Mobile SIM card, it's 
essentially about "CPHS: ..." files (6F16, 6F13, 6F15), on Service 
Dialing Numbers (6F49), on Phase identification (6FAE). I guess phase 
identification file is important, isn't it ?

  * on AF20 file (GSM ciphering key Kc), I see this error message :

------------
ofonod[11230]: Requested file structure differs from SIM: 4f20
------------

  * some AT commands fails : AT+CCWE (Call meter max event), AT+CPSB 
(fixed with AT+CNSMOD quirk), AT+CNAP (Calling name presentation). Must 
I add quirk for all theses commands ?

King regards,
Viallard Anthony.

This is generally a vendor-specific command or some sort of setting in 
the firmware.  What it means is that when the modem is brought up into 
Online mode, it does not automatically try to attach to the GPRS 
network, but instead waits to be explicitly told to attach via AT+CGATT=1

No idea what this is...

Yes, FF just means the record is empty.

If this is a 3G card, then this is normal.  And many of the files are 
optional in the first place.

That one is indeed strange...

Your modem might simply not support these...

Hello,

I think I found a solution about this issue !

If I set the bearer for SMS at "cs-only", it works perfectly.

Therefore, I think there an problem in the firmware of my chip about the 
"cs-prefered" mode.

I will see this with simcom and update my conclusion with their answer.

Anthony Viallard.
