iPhone Bluetooth pairing without confirming passcode

In my BLE app, the user story is like, bluetooth pairing should happen without the passcode confirmation step. As far as i have researched so far, it is possible in Android (like Android Bluetooth Pairing without User Enter Pin and Confirmation Using Android API)

Is it possible in iPhone?

Yes, but the user still needs to confirm OK in a popup. – Emil

Sadly, on iOS it is not possible to skip the pairing dialog. It is directly sent from the OS. It is a strict convention from apple that apps are not able to skip security processes.

Some additional information:

Dependent on the IOCapabilityResponse from the peripheral device on bluetooth level iOS will show you a dialog asking to pair or to confirm a pass code. If iOS will show you the dialog at all depends if the bondable flag is set in the IOCapabilityResponse from the peripheral.

There are three types of connection in BLE:

  • connection: pin not required, connection not secure
  • pair: pin could be requested or not, connection secured with short term key, a popup will be displayed
  • bond: pin could be requested or not, connection secured with long term key, a popup will be displayed

All of these method are managed by BLE peripheral firmware, iOS only adapts its connection based on how the peripheral is configured
