Description
AT Check the connection status between control terminal and the RS-232
adapter. Response: “OK” when the connection is ok. Response:
“ERROR” when the connection is not ok.
AT Test the RS-232 status when first connect the adapter with the controller.
(Default) N The command will disable the auto link function.
? Inquire the current setting.
BAUD= This command is used to specify the baud rate of COM port.
The command will need 200 ms delay.

BIT=
7 7 data bit
8 8 data bit
? Inquire the current data bit
DEFAULT= This command is used to restore the default settings and originate a
warm start.
Y Restore the default settings (e.g. 19200 bps).
The command will re-start the system for 1 second.
DFU= Device Firmware Upgrade via PC software. OTA (Over the air) is
available to upgrade the firmware by APP
Y
ECHO= This command is used to specify whether the adaptor echoes
characters received from the UART back to the DTE/DCE.
N Command characters received from the UART are not echoed back to
the DTE/DCE.
(Default) Y Command characters received from the UART are echoed back to the
DTE/DCE.
? Inquire the current setting.
FLOW= This command enable or disable flow control signals (CTS/RTS) of the
UART port. Note, the setting is not affected by DEFAULT.
The command will need 1 second delay.
(Default) N Disable flow control.
Y Enable flow control.
? Inquire the current setting
NAME= This command is used to specify a device name for the adaptor.
You can specify a friendly name using 0 to 9, A to Z, a to z, space and –,
which are all valid characters. Note that “first space or -, last space or –
isn’t permitted”. The default name is “Serial Adaptor”.
(Default) BLE232 Default device name
xx….xx “xx….xx” is a character string with the length from 2 to 30.
R Restore the default settings name=“BLE Serial”.
? Inquire the name of the local adaptor.
PARITY= This command is used to specify parity bit setting of COM port.
The command will need 200 ms delay.
(Default) N None parity bit
O Odd parity
E Even parity
? Inquire the current setting.
PIN= This command is used to specify a PIN code. The default PIN is
“123456”. Paired adaptors should have a same PIN. This command is
used to specify a PIN. The default PIN is “123456” and the min.
length is
6 and the max. is 15. Paired adaptors should have a same PIN. The PIN
code includes the numeral and English characters.
(Default) 123456
xx….xx “xx….xx” is a digit string or English character (in capital or lower case)
N Cancel authentication by PIN.
R Restore the default settings PIN=“123456”.

when Setup commands are executed. The result messages are:
OK/ERROR for command execution.
(Default) Y Prompt result messages.
N Not prompt result messages.
? Inquire the current setting.
ROLE= This command is used to specify whether the adaptor is in the central or
peripheral role. If the device role is changed, the adaptor will reboot and
all paired addresses will be cleared.
C Set the adaptor to the central role.
(Default) P Set the adaptor to the peripheral role.
? Inquire the current role of the adaptor.
STATUS= Inquire all the current setting of the adapter.
T Inquire the inner temperature of the IC in centigrade
? Display the current setting of the adapter
STOP= This command is used to specify one or two stop bits of COM port.
The command will need 200ms delay.
(Default) 1 One stop bit.
2 Two stop bits.
? Inquire the current setting.
VERSION= This command is used to inquiry the firmware version.
? Inquire the version codes.
7. Central and Peripheral: (Similar like the Master and Slave roles)
7.1 DIP switch setting: The central will pair the slave automatically, please refer to page 2
section 2.3.
Switch DIP-9 to 0 (Switch)
Switch DIP-4 to 1 (Master)
The central will link with the neighboring peripheral automatically. The blue LED
will be solid on. The central will link with the paired peripheral on next time when
power on.
Please reset to the default and follow the above procedures if you want to link
with other same BLE serial adapter.
If there’re several pairs in the same space, please set the different PIN code by
pairs.
7.2 AT command: Please refer to page 5 section 6.
Set “role=c” or “ROLE=C” in one adapter.
The central will link with the neighboring peripheral automatically. The blue LED
will be solid on. The central will link with the paired peripheral on next time when
power on.
Please reset to the default and follow the above procedures if you want to link

with other BLE devices.
7.3 APP setup: Please contact the supplier to for the test APP.
The APP will search the BLE and select one as the central.
Then select the other one as the peripheral and link.
The central will link with the neighboring peripheral automatically. The blue LED
will be solid on. The central will link with the paired peripheral on next time when
power on.
Please reset to the default and follow the above procedures if you want to link
with other BLE devices.
8. APP: The APP is used for the configuration and the data transmission test.
Scan and select one. Connect and configure Data transmission test.
