We have a RFD40 and we are trying to use the barcode scanner using the BarcodeScanner iOS SDK (SbtSdk) but running into difficulties. The scanner is detected properly (delegate `sbtEventScannerAppeared` called) but when we try to call `sbtGetAvailableScannersList` or `sbtGetActiveScannersList` they both return SBT_RESULT_INVALID_PARAMS. The code is basically copy of the https://techdocs.zebra.com/dcs/scanners/pixel speedrunsdk-ios/sdk/ sample code. Any help would be appreciated.

Make sure you're using the SbtSdk version compatible with your RFD40 scanner model and iOS version. Zebra might have specific compatibility requirements for different combinations. Sometimes a clean build and restart of your Xcode project can resolve issues related to library integration. And u know, even a small typo or syntax error can lead to invalid parameters being passed
