we are looking for consultant to advise on RTOS and wifi, if he is available then we will send series of questions and he provides answers and charge us for the service. Typical questions we will ask are like: 1. What is the pro and con of using Linux vs RTOS like [[login to view URL]<wbr />index][1] on ARM chip.
2. Can we customize wifi to suit our application? we need a private network that is accessed only by our own ARM devices, we will have TCIP stack in the ARM chip and will use wifi chip like Marvell etc. We tried using commercial router and repeaters but at times they hang or traffic slows but we have no clue on why they happen or how to fix them because their internal working is unknown to us. We thus exploring if we can just use our ARM+Marvell wifi chip to create repeaters etc and use our own rules for our wifi network.
3. We also have another application which requires the ARM to have bluetooth link, there will be no wifi on this application. We need advise on choice of bluetooth solution.
