We recently made a change to the LLRP portion of our Data Capture software
such that the ROReport is generated when the AccessReportTrigger is
activated. This change was made to reduce the number of unnecessary tag
reports. It seems works well on our Impinj Speedway reader but the Rifidi
1.5 simulator fails to send a report.
The rfid llrp inventory involves one ROSpec and one AccessSpec attached to
it, the report triggers for ROSpec and AccessSpec are:
ROSpecReport:
Trigger: 0
N: ignored
(No report for ROSpec)
AccessSpecReport:
Trigger: 1
(End of AccessSpec)
Here is the basic flow we are seeing with our Impinj reader.
1. ADD_ROSPEC command:
4,14,0,0,0,0,0,0,0,0,0,b1,0,46,0,0,0,1,0,0,0,b2,0,12,0,b3,0,5,0,0,b6,0,9,0,0,0,0,0,0,b7,0,18,0,1,0,0,0,b8,0,9,0,0,0,0,0,0,ba,0,7,30,39,1,
0,ed,0,12,0,0,1,0,ee,0,b,ff,c0,1,5c,0,5,0}
0,ed,0,12,0, ---> ROReportTrigger = 0 (NONE),
2.ADD_ACCESSSPEC command:
4,28,0,0,0,0,0,0,0,0,0,cf,0,65,0,0,0,1,0,0,1,0,0,0,0,1,0,d0,0,7,0,0,0,0,d1,0,49,1,52,0,27,1,53,0,23,60,0,20,0,60,0,0,0,0,0,0,0,0,0,0,0,0,0,60,0,0,0,0,0,0,0,0,0,0,0,0,1,55,0,f,0,1,0,0,0,0,c0,0,0,0,2,1,55,0,f,0,2,0,0,0,0,80,0,0,0,2,
0,ef,0,5,1,
0,ef,0,5,1, -------> AccessReportTrigger = 1 (End of AccessSpec)
3. The ROReport including AccessSpec result
4,3d(61) 0,0,0,62 0,0,9,13 0,f0(240) 0,58
8d,30,8,33,b2,dd,d9,5,80,35,5,0,16,89,0,0,0,1,8e,0,1,8a,30,39,81,0,1,86,d6,87,0,1,82,0,4,43,e8,96,73,2,d8,84,0,4,43,e8,96,73,2,d8,88,0,1,90,0,0,0,1,1,5d,0,d,0,0,1,0,2,60,0,0,0,1,5d,0,d,0,0,2,0,2,e2,0,10,61
The last several bytes show the result report for AccessSpec:,
90,0,0,0,1, ---> AccessSpec Id =1
1,5d,0,d,0,0,1,0,2,60,0,0,0,
1,5d,0,d,0,0,2,0,2,e2,0,10,61 ---> read operation results
