I met a problem when have ATS test.The iphone can communicate with accessory through ATX box.But if adding Beagle usb 480,the USB communication became bad. So I can't pass ATX test.It is strange to me that USB analyzer can make the USB communicate bad.
Can any engineer help me?Thanks!
Hi Matthew,
I'd be happy to help as I'm also developing an accessory.
Can you tell me about the ATS box and USB breakout you are using? I am personally finding the items on the procurement portal extremely confusing. Is it simply a device for piping raw communications between Lightning and USB?
If I can get a similar setup, we can work together to sort out your problem.
Cheers!
Hello guys. I've been looking for answers all over the internet.
Maybe you can help me out.
So my company is making usb devices that connect via USB. It's a proprietary protocol, but they are using regular USB Endpoint types.
I guess I cannot simply use the camera USB Lightning adaptor to connect the devices and then use the External Accessory framework, right?
Since, when I connect the device I am told right away that it's not supported.
It only supports the Picture Transfer Protocol and midi as I understand.
So, do we have to develop our own Lightning to USB adaptor when we want to make all of our devices connect to iOS devices?
How much hardware "logic" does such an adaptor have to include when all I want is receive and send raw usb packets in iOS via lightning?
Thanks so much for your help!
