Filtering BLE scan to show only Mdek1001 device

Hi there. I am developing an independent android application for personal project. I cant seem to filter the mdek1001 devices based on the network node service uuid: 680c21d9-c946-4c1f-9c11-baa1c21329e7
after initiating a BLE scan. Am I using the wrong uuid here? Thanks in advance.

Did you every get it to work? I am trying you use [startScan() ]but it isn’t seeing anything.
