https://devzone.nordicsemi.com/f/nordic-q-a/48787/dynamic-notification-changeHi all I am using a nRF52840 with SDK 15.3.0 and s140_nrf52_6.1.1 soft device. My application is a multi-peripheral device that has a common service, each peripheral can have different characteristic read/write permissions for this service.

Or could there be another way?</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/194908?ContentTypeID=1Wed, 26 Jun 2019 13:48:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:21fc2594-9e9d-408c-aa4e-18cac582d007Jared<p>Hi,</p> <p>Unfortunately, there isn&#39;t any API for changing the notification bit in the CCCD before a connection.&nbsp;</p> <p>Jared</p><div style="clear:both;"></div>
