3.2.20. GET BAUD RATE
Is used to read UART baud rate.
Host Command
Module Response
BAUDRATE parameter is the baud rate value code.
If packet is recognized and correct, module will respond with baud rate value
code.
If the packet is false/not recognized, module will respond with NACK (0xEE).
Example:
PC
USB Smart I/O
means that the computer requests for baud rate value and module replies that
the baud rate has a value of 38400 bps.
3.2.21. SEND UART
Is used to command the module to send a series of data via UART line.
Host Command
Module Response
Up to 32 bytes parameter will be transmitted consecutively.
If packet is recognized and correct, module will respond with ACK (0xAA).
If the packet is false/not recognized, module will respond with NACK (0xEE).
Example:
PC
USB Smart I/O
will send 0x01, 0x02, and 0x03 data via UART line.
3.2.22. GET UART
Is used to command the module to read a series of data via UART line.
Host Command
Module Response
COUNT parameter is the amount of data that will be read.
If packet is recognized and correct, module will respond with data reading
results. These are the received data (maximum 32 bytes).
If the received data is more than 32 bytes, then the 33rd data onwards will
overwrite the first data and onwards (roll-over).
If the COUNT value is larger than the amount of data on the buffer, then the
module will only send the data on the buffer.
