Tried to read through all the information on the project page before asking, but not everything is clear yet :) So what I would like to achieve is basically the man-in-the-middle (mitm) mode. I do not actually need to modify any communication on its way, all I would like to do is to have: a) the sim card in a reader connected to host (A), while b) the gsm module is connected to an other host (B) and relaying their communication back and forth through some IP network. I guess I would need two pieces of simtrace hardware for that, as well as firmware and software modifications. Now the questions :) - Do you think this could work with the current hw/fw design? - Has anyone done something similar in the past? - What would be the maximum network delay allowed? - Do you know of any alternative solutions for my needs? Would be great to hear from you. Thanks, Balazs ps: I would also be willing to pay for professional consultancy services on this topic.
