class NIMMSTABLEScanner : ScannerWithScanJobsAndCache
NIMMSTA BLE Scanner which is a separate layer between Android Scanner and UI in order to
It's based on Scan-Jobs, which are delegated to the BLEScanner and then executed until cancelled or reach a timeout. By doing that all scanning within the NIMMSTA App is combined and managed from one place and one place only.
It is able to filter on Scan Codes which means that you show a barcode to the HS 50 in format XXConnectHSD50XX:ABCDE where ABCDE is replaced by a random 5 character string. The HS 50 then provides this string in the BLE advertisement. This class can filter for that String in a ScanJob by setting filterOnCode to that code.
In order to obtain an instance of this, use NIMMSTAConnectionManager.nimmstaDeviceScanner.
