Hi，Sigurd Hellesvik，

Thanks for your kindly advice.

I found that my hid report map was missing several usages according to "ios Accessory-Design-Guidelines". I am still working on it.

thanks again

Regars,

Cashyu

Hello, what is the problem that I can't use apples? I also can't use apples now. May I communicate with you?

Hi Sunshine8166，

How did you implement hid touch on ios? Is it convenient to leave contact information for further communication?

Is this also a Digitizer? Maybe you should consider making a new question, and if possible also share the report map.

Could it be that this is not under the general mfi agreement. i.e. that you need another agreement to access the spec relevant to iOS. Probably not since the carplay spec is there.

Do you know if your multi touch screen HID is a BLE or Bluetooth classic device?

That's strange. I can not find the word Digitizer anywhere in the current version, R30. But as you say it is in the carplay section of the old document. So I would guess it is supported by carplay, but not by iOS.

i think it supports. 《MFi Accessory Interface Specification R18_NoRestriction》

19.3.5.1 Digitizer Support (Touchscreen and Touchpad)
A digitizer is a device that measures absolute spatial position, typically in two or more dimensions. CarPlay
supports the following types of digitizers:
19.3.5.1.1 Touchscreen
A touchscreen is a digitizer with an integrated display that allows the use of a finger for direct interaction with
a presented interface.

Hi,

Are you sure the Digitizer usage page is supported by iOS? As far as I can see it is not mentioned in the Accessory Interface specification.
