Qualcomm based cellular data modems wih Linux

This is the place where we gather information about the Quectel EC20, EC21 and EC25 modules, as well as other Qualcomm based cellular modems with built-in Linux processor.

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.
