Have you looked at the list of error codes at the end of the AT Commands document ❓

Of course 🙂 If I ask something else in this forum I’ll remember include these important details.

The only info I was able to find related to this error code is in the release notes of firmware 7.45 and that one also does not have a proper description:

[developer.sierrawireless.com/Res … \_45\_1.aspx](http://developer.sierrawireless.com/Resources/Resources/AirPrime/Software/Release_notes/Open_AT_Firmware_7_45_1.aspx)  
Issue number: 57376

This forum has also a post that mentions 561 which is from 2007: [https://forum.sierrawireless.com/t/debugging-dlls-in-visual-c-net/575/1](https://forum.sierrawireless.com/t/debugging-dlls-in-visual-c-net/575/1) but I’m not sure how applicable that one is to my situation as it is also not clear enough.

Sadly, that is by no means a foregone conclusion.
