making a multi tag inventory with CR95hf

I am using the ST iso19653 and CR95HF software libraries in my application and by following the example set in the M24LRXX code I can make an inventory of a single tag. I want to be able to regonise more than 1 tag in the field and have tried using the 16slot inventory command but this returns with an error. As there are no worked examples for the detection of multiple tags I am not sure how to set up the mask length and mask parameters.

You should have access in the library available on ST.com 

STSW-M24LR0073.7.0ActiveST

)

Check in the library the

 

lib_iso15693pcd.c file including the function ISO15693_RunAntiCollision.  This function runs an anticollision sequence and returns the number of tag seen and their UID.  Take care prior you have to perform the protocol select command.
