It appears that the decoder is getting confused somehow. If you look at the binary that you included, this is not an instance of the ImpinjBlockPermalockOpSpecResult parameter type. The VendorIdentifier is 25882 (Impinj), and the ParameterSubtype is 57 (ImpinjPeakRSSI). The remaining word is a signed 16-bit value indicating the RSSI in dBm*100, in this case -2750 (-27.50 dBm). I don't know much about the LTKJava parser, but it does not appear to be properly identifying the extended parameters included in the TagReportData LLRP parameter.

Basil Gasser, the error generated is the same but in different locations. I debug the class ImpinjBlockPermalockOpSpecResu lt and noticed that the error is generated when it creates an instance of the object ImpinjBlockPermalockResultType, specifically this code: result = new ImpinjBlockPermalockResultType (binary.subList (position, ImpinjBlockPermalockResultType.length ())); Ex: LLRPBitList binary: 00000000000000000110010100011010000000000000000000000000001110011111010101000010 LLRPBitList list: 11110101 value: 245 The constructor's ImpinjBlockPermalockResultType class is passed a LLRPBitList list. I noticed that LLRPBitList was varying between 11101000 and 11110101 (232 and 245). This value is assigned to an attribute named "value" (attribute present in the parent class unsignedByte) and is called isValidValue a method that checks if this value is between 0 and 6. So the exception is thrown (throw new IllegalArgumentException ("Value not allowed")). Await any suggestions. ------------------------------------------------------------------------------ _______________________________________________ llrp-toolkit-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/llrp-toolkit-devel
