4 Communication procedure
4.1 Overview
Communication is done in the following manner：
(1) Right after the power is turned on, the master and slave does not have wireless communication
and is in an invalid state.
(2) For sending/receiving a wireless packet, start the FH operation by inputting the @FHS command
(the master and the slave).
The master initiates RF transmission and reception.
The slave starts RF reception, wait for communication from the master.
(3) If FH synchronization acquisition, slave start also sent. After that, the slave will continue
in automatic synchronization.
(4) By TLC command to set the data you want to send.
(5) In FH synchronization acquisition, it will receive the data periodically from the
communication partner.
If the synchronization is out, it does not receive the data.
(6) To stop sending/receiving a wireless packet, type the @FHE command and quit the FH operation.
4.2 Send command
The command header is "@TLC", the terminator is CR+LF (0x0D 0x0A). There is no response to the
command.
Please send data as a binary data of 60-byte fixed.
Radio transmission will be run every 20ms. By @TLC command, it will update the transmitted data.
If @TLC command is not inputted, the previous data is wirelessly transmitted. If you also send
command has not been entered once, the data of all 0 is wireless transmitted.
【Send (update) format】
@TLC[Binary data 60 bytes][CRLF]
4.3 Received data
The received data is appended "RLC" of 3 bytes as a header.
The Received data is binary data of 60-byte fixed.
Radio reception will be run every 20ms. In a state that can't be wireless communication, it
will not be output to the wired.
【Reception format】Repeat
RXT[Binary data 60 bytes]
