Set Current Tag Protocol (93h)
To select a protocol, send the Set Current Tag Protocol code to the reader. A table of
valid protocol codes is found in Get Current Tag Protocol (63h)
. The following example sets
the protocol to GEN2:
Only protocols that are enabled in the reader are available. These protocols are listed in
the version information for the application, described in Get Boot Loader/Firmware Version
(03h).
Set Write TX Power (94h)
The Set Write TX Power command sets the power level to use for writing to tags. This is
necessary because a write operation may require a different RF power setting than a
read command. The format and arguments of this command are identical to the Set
Read TX Power command:
Set Frequency Hop Table (95h)
The Set Frequency Hop Table command sets the list of frequencies to use when
hopping. Each frequency is encoded as a 32-bit value in kHz. For instance, 915MHz is
encoded as 915000kHz, which is 0x000DF638. The maximum number of hop
frequencies is 62, since that is the maximum number of 32-bit values that can be sent
using a message packet. If fewer values are used, only those values are populated in the
table and the rest of the slots are ignored.
