https://devzone.nordicsemi.com/f/nordic-q-a/76059/ble-lesc-failsHi! We&#39;re developing an app which connects to BLE devices for different purposes. We&#39;ve successfully enabled MITM using windows(an example from Microsoft) , but are having problems enabling the LESC option, which is part of the BT v4.2 as I understanden-USTelligent Community 13Mon, 07 Jun 2021 14:05:32 GMThttps://devzone.nordicsemi.com/thread/313963?ContentTypeID=1Mon, 07 Jun 2021 14:05:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:914d3133-c0b8-4c63-a0c0-8894f752e625Simonr<p>You&#39;d like a central example application using LESC, correct? Our <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/ble_sdk_app_hrc.html">Heart Rate collector example</a> for instance demonstrates the use of LESC, so please give it a try. It should be able to connect automatically to a device running the <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/ble_sdk_app_hrs.html">Heart Rate service example</a> for instance, or you could modify it to connect to any device with the Heart Rate service at all.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
