I am investigating how to do bonding with iPhone. As a way, bonding is a way to occur when the iPhone accesses the characteristic that enabled securityen-USTelligent Community 13Wed, 20 Apr 2022 06:57:03 GMThttps://devzone.nordicsemi.com/thread/363753?ContentTypeID=1Wed, 20 Apr 2022 06:57:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9dd3b959-1b2d-42ba-82af-28047dacd91dSimonr<p>Hi</p> <p>First off, I see you&#39;re using the nRF5 SDK v17.0.0, which was replaced by a bug fix release (v17.0.2) which will properly handle errata on future devices with an unknown HW ID. If you&#39;re using SDK v17.0.0 for development, it&#39;s strongly recommended to switch to v17.0.2.</p> <p>Do you want the peripheral device to only be able to bond with iPhone devices? Or only to devices that you have access to? A peripheral device has no say during the connection phase I&#39;m afraid, but it can trig a disconnect if it is not &quot;on board&quot; with the device it connects to. Please check out the <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/lib_peer_manager.html">peer manager</a>&nbsp;documentation for information on how to manage BLE security in nRF devices.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
