https://devzone.nordicsemi.com/f/nordic-q-a/75342/poc-ble-securityHello, As part of a Proof of concept reason on nRF52840 based SDK15.2 and s132_nrf52_6.1.0_softdevice, our BLE communication should support Just Work security and no secure depending on Host requirement. Is this possible? If yes, how can be builten-USTelligent Community 13Thu, 20 May 2021 13:29:47 GMThttps://devzone.nordicsemi.com/thread/310781?ContentTypeID=1Thu, 20 May 2021 13:29:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b47b4532-9cfc-49b7-bfe8-b4b49ba0ce0cKenneth<p>Hi,</p> <p>If you use one of the BLE peripheral examples that use peer manager (for instance Heart Rate sensor), then you can find they all support Just Works. So I suggest that you use one of those as a starting point for you application. If you want to allow the peer to use the BLE peripheral device even without encryption, then you need to configure the security level on the database characteristics to OPEN (no encryption required).</p> <p>Kenneth</p><div style="clear:both;"></div>
