Hi Quinn, Noted, will use reply feature from now on. We are in the process of applying for MFi. Apart from the MFi certification, are there any other requirements for an EA-based solution? For example are there limits to how we can interact with the device? From what I have read about EASessions, we provide the communication protocol that will be used. Will this allow us to create custom protocols? Does this include selecting the USB interface/interfaces? We are just trying to determine the feasibility of developing an app to communicate with this device. If we are able to create custom protocols, and send USB packets to the device this way; what is the best way for us to create a test implementation in which we validate the solution will work? Thanks, Mike
