I have been reading whatever I could find in the forum, but have hit a few road blocks.
First of all, the library that is supplied in the SDK is built with the floating point feature to be done in software, which isn’t compatible with my kernel image doing it in the hardware. I read in other posts that it is possible to get hold of the source code for both full and lite SDK, with an NDA, which our company does have. Who can we contact for this?
I need to make use of the Multiple PDN support, I found the document 2174187-1.0 and found a few posts in this forum regarding this. One of the first things the document explains, is to enable the RMNET in the module’s USB composition, using AT!USBCOMP, however that fails on my modem with the message ERROR. I am using the latest Verizon image which might have locked this feature? From what I can read there is a special command which unlocks certain features in the modem, but it can brick the modem too in certain instances? What is the correct way of doing this, if there really is any? These modems are too expensive to kill
I got the Gobi drivers built and running on the modem, but since I can’t link against the provided library, I have been going the other way, updating my kernel to try to get the latest and greatest of the QMI_WWAN code.
There are a couple of other posts on other sites doing kind of the same thing, but I guess there is no support for this in this forum? I’m not getting much further than kernel 4.9.2, where as the later version of the QMI_WWAN driver has the MUX support that I guess is what I would really need.
I guess I either get the SDK up and running correctly, or abandon it altogether and use the implemented kernel stuff and spend the next few nights getting everything updated and running stable, but maybe it’s just waste of time. I’m hoping the SDK is the answer?
