Qualcomm based cellular data modems wih Linux¶
Please help us to grow this resource for the benefit of the general public.
It is a shame that Qualcomm doesn't disclose proper documentation for their products to the general public. There are many possible applications and use cases which are possible once more information about those devices is publicly available. Having the power of running customer/user-specific programs inside the Linux in the modem is very powerful, and can for example eliminate the use of a dedicated external processor in many M2M/IoT applications.

All information here is based on publicly found documents on the internet as well as studying the source code released by Qualcomm, Quectel and others as well as bits of reverse engineering on the devices themselves. We commit to legal forms of reverse engineering, such as running software in emulators, using tracing and debugging facilities.
