https://devzone.nordicsemi.com/f/nordic-q-a/5594/manufacturer-data-encryptionHi, I am using the sofdevice s110. I want to encrypt my manufacturer_data. However , the type of the advertising is BLE_GAP_ADV_TYPE_ADV_NONCONN_IND. I tried : nrf_ecb_init() and nrf_ecb_crypt(dest_buf,src_buf), it is not working.

The module is restricted and must be accessed through the SoftDevice.</p> </li> <li> <p>You should use the function <em>sd_ecb_block_encrypt()</em> instead. It takes a <em>nrf_ecb_hal_data_t</em> which contains a cleartext and encryption key field used an inputs. The encrypted data will be stored in the ciphertext field.</p> </li> </ol><div style="clear:both;"></div>
