Data Connection Failure error code

Hello,

Would you know where can I find documentation on what the Data Connection errors mean, such as those visible in the picture below?

Thank you,
Best regards,
Ben

Hi @jyijyi ,

Thanks, however I’m not sure to understand how to interpret the codes actually being returned:

Code 3
Verbose 2001

Am I missing something?

Apologies, didn’t see the edit to your message.

Is there a place for me to check those codes?

you don’t have that source code pa_mdc_qmi.c as it is not for public

Ok

Would it be possible to just get the mapping of the possible error codes though (without access to the entire file)?

maybe this qaGobiApiTableCallEndReasons.h can help:

Hello,

I am now seeing error 2504, do you know what error it means?

Thank you

jyijyi · February 20, 2023, 8:41am

it means " INVALID SIM STATE"
Have you checked AT+CPIN? and AT+CGREG?

BTW, did you download the Linux QMI SDK to check?

Hello,

I’ve downloaded the documentation now and can see the error codes, thank you.

Hello,
I’ve just observed the following error

Data connection failure Verbose Call End provided Type 3, Verbose 1110

It is not documented in the qaGobiApiTableCallEndReasons.h file, would you be able to retrieve the code?

jyijyi · March 14, 2023, 4:17pm

it seems to be EMM problem

ben1 · March 14, 2023, 4:31pm

Thanks, do you have any more details please?
I’m not sure to see what it means

jyijyi · March 14, 2023, 4:32pm

no, i don’t have more detail, it is network stuff problem
