I am developing a device that will communicate with an app installed on an iOS device. I have some doubts:
If I use an MFi cable, do I need to license my product?
To communicate by serial port, is it necessary to license the product?
Is there any way to communicate with the USB cable that does not require the license?
I have nowhere found the cost to license the product, for both development and manufacturing.
The device will be connected and powered over USB.
Note: A proprietary iOS application will be developed to communicate with the hardware.
