I'm not sure where to go from here, I've filled in the "appeal" form but had no response.
My app has somehow been interpreted to 'only work with specific hardware' - this is not the case it works wither either specific hardware OR a third party piece of software (which is freely available)
The third party software provides a TCP server and my app connects to it as a client.
I have been rejected four times now because I haven't provided a 'video to show the paring process with the dedicated hardware'
There isn't a 'pairing process' any more than there is a pairing process between Safari and a website or Mail and an IMAP server, it literally connects to the specified IP and Port.
I've provided a video of this (showing a screen capture of the software in question, and a screen capture from an actual iOS device - my iPhone - showing me connecting to the other application in the app, and demonstrating the functionality of the app - but keep being told I need to provide a video with hardware.
I don't own the hardware version, I use the software version. It's exactly the same process and software whether it is running on hardware or software.
