BoT-CLE310 Protocol (AT-COMMAND)
OVERVIEW
This document defines a communications protocol through UART (serial port)
between customers’ MCU (hereinafter referred to as “HOST”) connected with
"Chipsen BoT-CLE310
BoT-CLE1X0 Module" (hereinafter referred to as “BT”) and
UART interface.
1.1. Basic Protocol Rule
• The transmission and receipt of data between the HOST and the BT is
based on the UART(serial port) interface.
• Default setting values of UART (serial port)
■ Baud rate : 9600bps
■ Data bit : 8
■ P ar it y b i t : no n e
■ Stop bit : 1
■ Flow Control : None
■ The aforementioned matters are default setting values, and if y o u w a n t t o
change
such values, please request a modification thereto when
preparing the BT firmware or modify them using the applicable AT
command (AT + UART = BaudRate).
• Communication direction
■ REQUEST (HOST → BT): generated from the HOST and transmitted to the BT
■ NOTIFY (BT → HOST): notify the basic state of the BT, as a
message that is
generated from the BT and transmitted to the HOST
■ RESPONSE ( BT → HOST): a response to the REQUEST, as a message that
is generated from the BT and transmitted to the HOST
• Communication rule
All protocols consist of a combination of ASCII values and notify the end
of Command through <Carriage Return>.
E.g.) REQUEST - the mode state of the current device: AT+VER?
Command AT+VER?
