https://devzone.nordicsemi.com/f/nordic-q-a/35987/advertisingHi I’ve downloaded nRF5_SDK_11.0.0_89a8197 and starting with examples from \examples\ble_peripheral\???\pca10040\s132\arm5_no_packs\ I&#39;m writing an application to be running on BLE. the other &quot;side&quot; is an BLE application running on a cellphone.en-USTelligent Community 13Mon, 02 Jul 2018 14:46:33 GMThttps://devzone.nordicsemi.com/thread/138557?ContentTypeID=1Mon, 02 Jul 2018 14:46:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9f6167e9-bb17-45c4-bd9e-7ce57d25baaftesc<p>Hi,</p> <p>First of all I highly recommend using the latest SDK version for nRF52 development.&nbsp; Currently that is nRF5 SDK 15.0.0. Version 11 was the first version with nRF52 support, (for engineering versions of the nRF52832 if I recall correctly,) but there has been a lot of improvements since then. See the release notes of the current SDK for lists of added features and bugfixes over the years.</p> <p>For identifying the different types I suggest using &quot;manufacturer specific data&quot; in the advertisements. It is an advertisement data type that is specifically made for this kind of use case. Then the central (or scanner) can read the type directly from the advertisement, and you do not even need to make a connection to do so.</p> <p>Manufacturer specific data is mentioned in <a href="https://devzone.nordicsemi.com/tutorials/b/bluetooth-low-energy/posts/ble-advertising-a-beginners-tutorial">Bluetooth low energy Advertising, a beginner&#39;s tutorial</a>, and although that tutorial is old (SDK v11) the concept is still the same and there are few (if any) changes to the manufacturer specific data part.</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
