https://devzone.nordicsemi.com/f/nordic-q-a/115174/lock-nrf52810-to-only-allow-one-type-of-software-to-connectHello, Thank you for reading my question. My company and I have developed a BLE device for use with windows computers based on the nrf52810. The device pairs with windows, then connects to a separate software I wrote for windows PCs to control the deviceen-USTelligent Community 13Wed, 02 Oct 2024 13:21:45 GMThttps://devzone.nordicsemi.com/thread/504704?ContentTypeID=1Wed, 02 Oct 2024 13:21:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d02262e8-8d33-4392-9c69-56f0991de7baAmanda Hsieh<p>Hi,&nbsp;</p> <p><span><span>You also can scan and connect with specific types and modes to ensure your device can only be used with your software.&nbsp;For example, you could design your software to only work with devices that have the service UUID/address/name. Similarly, you could design your device to only accept connections from software that meet the condition.&nbsp;</span></span><span><span>See the Scan&nbsp;</span></span><a href="https://docs.nordicsemi.com/bundle/ncs-2.7.0/page/nrf/libraries/bluetooth_services/scan.html#filtering">Filtering</a>&nbsp;doc and this tutorial&nbsp;<a href="https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/software/posts/building-a-ble-application-on-ncs-sdk---contrasting-to-softdevice-based-ble-applications---part-2-central-role">Building a Bluetooth application on nRF Connect SDK - Contrasting to SoftDevice - Part 2 Central role</a>.&nbsp;</p> <div>Regards,<br />Amanda H.</div> <div></div> <div></div><div style="clear:both;"></div>
