How to know if a connected device supports Bluetooth LE privacy ?

[manu]

Hello,

I want to use privacy (BLE_GAP_ADDR_TYPE_RANDOM_PRIVATE_RESOLVABLE) if the connected device support this feature. As far as i know it's not possible at application level to start a feature exchange procedure or get the request if the master has initited the procedure. So How can i know if the devices support privacy?

Thank u

Ï guess you cannot without trying once. Your application needs to gracefully handle the event BLE_GAP_EVT_AUTH_STATUS to know . I am not aware of a way of knowing this before trying.

Thanks for the answer. I finally decide not to implement privacy because of the poor compatibility.

Understandable.
