One week ago at the 33C3 conference, Osmocom core developers Holger and Harald first publicly presented about a new Osmocom project to analyze and reverse engineer a series of Qualcomm-based Cellular modems that run a version of GNU/Linux inside the modem itself. Feel free to see the video recording and/or the slides for more information
At the time the talk was presented, all related information that was gathered by them has been released inside the wiki of a new Osmocom project called Qualcomm Linux Modems by Quectel & Co
We're looking forward to grow this resource further and further - hopefully with your help. Osmocom is a collaborative, community based project, after all.
