I can accept incomming call in Android , Use Play Key or Key "Media select Telephone" 0x8C .But this can not work in IOS10.3.1. In IOS PLAY/PAUSE/PRE TRACK/NEXT TRACK/VOLUME INCREMENT/DECREMENT can work, But can not Answer call . I set the key code Based on the doc USB HID usage table. I have checked in this forum and Google for server days .

Hi Bigz,

I have no information if you can do that with HID on iOS but you can think of using ANCS ?

"The actual actions performed by the NP on behalf of the NC are determined by the NP and vary depending on the iOS notification they are performed on. For example, performing a positive action on an Incoming Call notification may answer it, while performing a negative action may decline it."

We have an ANCS example in our SDK showing this.
