Chapter 5 Internal Control
The operation of the transmission wave module model GX changes as follows.
"Start-up"
After the power is turned on and the hardware is reset, the module initializes the internal circuits,
outputs the module ID as a startup message to the UART interface, and then transitions to the
idle state.
"Idle"
When the module is idle, it waits for a command from the UART interface, and if no command
(or trigger signal) is received, there is no RF action.
"Trigger action"
The module can identify that the trigger signal (SYNC-IN) is low in all states. But it should following a
Prepare main flash Usart command, then the SYNC-IN signal comes.
After identifying the trigger signal, the trigger transmission operation is performed. (Minimum time of
trigger signal is
100uS or more) To implement one-shot trigger operation, do not set the trigger
signal to the Low state for
50mS or more.
"Command operation"
The module can receive UART commands in any state, When the command received from the UART
interface is valid, the processing specified by the command is executed. Command processing is a send
operation or a message response to the UART interface. After the command execution is completed, this
product transits to the idle state.
"Transmission operation"
As a transmission operation, the module controls the wireless circuit and transmits the wireless
message specified by the trigger signal or transmission request command in the preset wireless mode.
After execution of the transmission operation is completed, this product transits to the idle state.
