SkyeTek Protocol v2
The M1-Mini device communicates with a host controller using the SkyeTek Protocol v2 for all host interfaces. The
SkyeTek Protocol defines the data exchange between a host controller and a RFID radio module. It specifies how a
host controller can address, configure and command a radio module in order to read and write to RFID tags and
smart labels.
The following sections of this document explain a very basic overview of the protocol. Refer to the SkyeTek Protocol
v2 Guide document for detailed information.
