What are the general requirements to use a Sierra Wireless MC7430/MC7455 in LEDE? I have been researching, but have a few miscellaneous questions.
What I know so far is the modem can be in either MBIM or QMI mode, and I need to be using kernel 4.5 or above (I am using 4.9) to use QMI mode features. There is also a Sierra Gobi driver set that I could use. Is that as simple as compiling it, then loading it into a running LEDE installation using modprobe?
To control and use the modem I need several software packages, but could someone post a definitive list of them here for either QMI or MBIM mode? I see several online, but I have yet to have success with any of those. They generally suggest using uqmi or umbim.
ModemManager: This looks very nice. If I want to use this, will I need to compile my own LEDE image with it added via feeds? Any plans in the near future to make ModemManager a regular package?
