6.5.5.1. Wakeup
6.5.5.1.1. Command Transmission
6.5.5.2.1. Command Transmission
6.5.5.1.2. Wakeup Response
To wake a READER in sleep mode, a very short string must
be sent by the LSC. This will be detected by the hardware and
will awaken the READER. As this is a hardware-oriented command,
the format is different then all the other commands.
LSC > Reader
A WAKEUP string transmission wakens the READER. The READER
does not respond to such a string. After the command is issued the
READER is ready to receive regular commands.
6.5.5.2. Execute RF Command.
This command enables communication sessions with the seals.
The LSC inserts the relevant information in the data field allowing
the reader to easily compile the final command string.
LSC > Reader
