I know one way is using pairing mechanism I can establish a secure connection but I want to know is there any other way thanen-USTelligent Community 13Mon, 27 Jan 2020 15:24:27 GMThttps://devzone.nordicsemi.com/thread/231223?ContentTypeID=1Mon, 27 Jan 2020 15:24:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:29d5fa74-7071-4754-995f-0aa1e186e238ovrebekk<p>Hi&nbsp;</p> <p>If you want to leverage the security procedures in the Bluetooth stack there is no way around pairing.&nbsp;It is during the pairing phase that the encryption keys are distributed, and without these encryption can&#39;t take place.&nbsp;</p> <p>The only way to secure the link without doing pairing is if you encrypt your data&nbsp;before you pass it to the Bluetooth stack, but then you have to implement the entire security protocol yourself.&nbsp;</p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>
