What is the meaning of: +QODM: "FUMO", Report Failed

IoT Modules LTE Standard Module
1

EC21
Custom board
After using AT+GPS=1
I get the URC: +QODM: “FUMO”, Report Failed

Where is this documented?
I have a bunch of PDF files for the EC21 but I can’t search all of them at once.
Do you have a web page that I can search for commands, responses, and URC messages?
What does it mean?

Thanks,

Dear Sir，
I think your command may be wrong. We currently do not have the web page you mentioned. Please refer to the document “Quectel_EC25&EC21_GNSS_AT_Commands_Manual” for your question.You can download it from our website: https://www.quectel.com/support/downloadb/TechnicalDocuments.htm?keys=EC21_GNSS_AT_Commands

I did not find QODM in the docs.
I guess that there is a command like AT+QODM that would produce a URC.
I do not use a QODM command, so why is the EC21 sending the QODM URC?

Thanks,
Bruce Graham

Hi,

Did you ever get a resolution to this? I have several modules that are constantly spitting this undocumented message out.

+QODM: “UI”,0,[NETE][/NETE]

[ ] chars are really < > but don’t show in page

I have also seen the FUMO report failed message

Did you find documentation? Thanks

Michael

This URC information is related to AT&T OMA DM function, if it have no any influence on your application, please skip it; if it already have the effect on your application, you can use the following command to disable it, it will take effect after reboot. Thanks!

The at+qodm=“fumo”,1,“autoreport 0” return ERROR and still has lot of thos QODM messages, @Kyson can you confirm this please?

We get +QODM: “FUMO”, Report Failed at end:

Thank you Kyson, I will try with the firmware update, meanwhile, I have a few questions about this issue:

  1. We have thousands of product with EC21 already in end customer’s hand, how to make firmware update seamlessly from there? does the older version has DFOTA support?

  2. Luckily we just have few test board has such issue internally (triggered by bug somewhere in a new development), but we still have to prevent this happen in any case, is there any workaround to prevent this without firmware update? such as AT&F or some undocumented command? (I tested AT&F but doesn’t help).

  3. I am working on new module BG95M3 as well, should I add this command into there too?

Thanks
Richard L.
