I want to get the iphone mute when call coming with BLE HIDS service, but I don't know the HIDS key size. Who can help me to solve it?

Hi,

Could you give me more details on what you have tried? What exactly doesn't work?

Are you able to connect, do you get any error codes, able to send any data?

What SDK and Softdevice version are you using?

Thank you for your help. I don't konw how to say that I got it worked yesterday just when I sign out from this web. You just to send the volumn down or up when phone coming, it will mute.
