I’m one of your customers who has passion to develop beautiful products. As an independent developer, I am writing to seek your advice regarding a communication between microcontroller’s USB (CDC device) and iOS devices via lightning connector.
I have been working on a project where I aim to establish USB communication between the microcontroller and Android devices. I have encountered difficulties when attempting to establish the same connection with iOS devices.
I used different STM32 microcontrollers with USB device capability by now. I use F series and L series generally for my projects.
I have explored various approaches, but the communication consistently fails. I believe that may be missing a certain circuitary part or specifications required for compatibility with iOS devices. Therefore, I kindly request your guidance and support to identify and meet these requirements. Any recommendations, resources, or updates that could assist me in establishing a successful connection with iOS devices would be greatly appreciated. Specially, can you even say your microcontrollers USB 2.0 protocol is compatible with ios devices? Is there a prototype, project or tutorial about this issue?
Thank you in advance for your attention to this matter. I eagerly await your response and any assistance you can provide. Please feel free to contact me if you require any additional information or if there is a more appropriate channel through which I can seek support.
