Apologies if I'm writing in the wrong place for this, please let me know where I can better fit my question if it is.

I'm looking to get some form of documentation on the QMI standard, more specifically, I'm looking to be able to understand the different error messages that could be outputted by a QMI compatible modem.

I was referred here by another forum post (, mentioning that I should be able to find the documentation here, however I was unable to find it so far. Could you refer me to where I can find this?

This is not detailed documentation of the QMI protocol. This is an open source library that implements a small fraction of the basic functionality of QMI.

I am currently in the same situation. I am trying to allocate a client for WDA and get an error "Internal".

Is there some description, which described QMI requests and answers, so I can verify that my sent data is correct.
