We are a small company specialized in hydrological measurements and remote data acquisition.
We are planning to replace our current hardware solution (microcontroller + gsm module) with the new one based on only EC21 module & QuecOpen - Open Linux.
We’ve studied the documentation for both EC21 and QuecOpen and it looks like it would be perfect for our needs, but we have a few questions:
Is every ES21 module ready for developing with QuectOpen or a different firmware must be flashed first? If yes, how do we obtain such a firmware (our module is EC21-EU).
In all the documentation it is only mentioned that we have to install the QuecOpen SDK, but how do we obtain one, it look it can not be freely downloaded?
