https://devzone.nordicsemi.com/f/nordic-q-a/61281/questions-related-to-uuidDear nordic, I am developing a robot controller(Central, nRF51822). However, I am having a problem with UUID. And I am using the ble_central (s130 ble_app_uart) example. The screenshot below(nRF Connect App) and UUID is the informationen-USTelligent Community 13Tue, 12 May 2020 12:47:29 GMThttps://devzone.nordicsemi.com/thread/249484?ContentTypeID=1Tue, 12 May 2020 12:47:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:875e96d1-ced2-4c32-ab1c-e23f601df9a0Hung Bui<p>Duplicated case:&nbsp;<a href="https://devzone.nordicsemi.com/f/nordic-q-a/61243/questions-related-to-uuid/249323#249323">https://devzone.nordicsemi.com/f/nordic-q-a/61243/questions-related-to-uuid/249323</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/249401?ContentTypeID=1Tue, 12 May 2020 10:12:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3e14c451-2486-4140-981d-226dbaa01cc9Turbo J<p>There will be a significant amount of changes:</p> <p>The idea is to add <em>each</em> of the UUIDs as a new vendor specific UUID using sd_ble_uuid_vs_add ()&nbsp; function.</p> <p>This needs a change in SD BLE configuration to allow enough vendor specific UUIDs. In turn, the softdevice needs more RAM, so you need to change the linker configuration/script in order to reflect this.</p><div style="clear:both;"></div>
