Embedded Command
(bit 3) 0x0004 An embedded command is specified in the request and
will be executed on each inventoried tag.
Note: This bit should only be set when using the Tag
Inventory With Embedded Operations syntax.
Note: 1- Only one of these flags should be set since both Antenna 1 and 2 cannot be the starting antenna.
2 -Multiple Flags can be set (perform a binary OR) to specify different behaviors. ex: Search Flags = 0x0006
indicates a multiple antenna search starting on antenna2 is to be performed and the embedded command
specified is to be executed on each tag.
Note: When performing multi-antenna searches and Tag Singulation/Select Functionality is used, the
Select operation will be performed once per antenna. More specifically, during a single Tag Inventory
with Select operation a Select will be issued at the start of searching on each antenna in use. If the
search comes back around to an antenna during the same command the Select is not issued again.
