We need a simple way to validate communications over the Lightning port with an MFi accessory we are developing. The hardware is not yet ready, so I'm looking for the easiest possible method of monitoring the data link.
Ideally, this would just be an FTDI-style cable with a lightning connector on one end and a UART on the other, with a decoder chip in between. I know there are the Redpark cables but I'm not sure that will send the data 'raw'.
We will be attempting to validate communications via External Accessory Framework with the Lightning-connected accessory while the app is in the background.
Any other suggestions? Thanks!
