Dans it use a preshared passkey ? Is that secured (man in the middle, privacy, ...) ?en-USTelligent Community 13Sun, 07 Jan 2018 08:45:19 GMTRE: Secured with passkey NUS and NUS_Chttps://devzone.nordicsemi.com/thread/112413?ContentTypeID=1Sun, 07 Jan 2018 08:45:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3fcdfc43-763e-424d-833b-260811e92021Fabien Comte<p>Hello, Thank you for your help.</p><div style="clear:both;"></div>RE: Secured with passkey NUS and NUS_Chttps://devzone.nordicsemi.com/thread/112412?ContentTypeID=1Mon, 28 Aug 2017 12:56:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8ec6625e-5309-4b5c-84b6-c3cc0aca4374run_ar<p>Legacy pairing with Preshared / static passkey is not considered very secure, as it&#39;s only a 6 digit key it can be easily brute forced</p> <p>LESC just works would probably be better, but doesn&#39;t offer Authentication. IO capabilities would be an advantage, so you get authentication too.</p> <p>Depending on your security recuirements I would recommend looking at the ble_central_and_peripheral\experimental\ble_app_multirole_lesc example.</p><div style="clear:both;"></div>
