GS-BT2416C2.AT1

AT command

25/32

A.25

AT+ECHO

Enable or disable the output of events and functional messages by the module.

Syntax: AT+ECHO=<ON,OFF>

Parameters:

ON: The ECHO mode is enabled and every message or events by the module will

be outputted. (default)

OFF: The ECHO mode is disabled and no output will be generated.

Return value: <OK, ERROR>

A.26

AT+UARTSETUP

Set the local UART settings. The changes take affect immediately after the OK response. It

is advisable to issue an AT command after the AT+UARTSETUP in order to make sure the

MCU is synchronized up correctly with the new settings. The new settings are used both for

the COMMAND MODE and DATA MODE. Use the command AT+BTMACROSTART to store

a startup setting for the UART. Is not allowed to use AT+UARTSETUP command in a macro!

Due to internal time needed to write a flash memory area a little time delay is possible

before any return value.

Syntax: AT+UARTSETUP=BaudRate, DataBits, Parity, Stopbits, Fc

Parameters:

Baud Rate: UART baud rate in bps. Possible values are: 300, 1200, 2400, 4800,

9600 (default), 19200, 38400, 57600, 115200, 153600, 230400, 460800.

DataBits: possible values are 5, 6, 7, 8 (default)

Parity: possible values are None (default), Even, Odd

StopBits: possible values are 1 (default), 2

Fc: flow control. Possible values are None (default), Hardware

Return value: <OK, ERROR>

A.27

AT+UARTSETUP=?

Output the current UART configuration settings. The command generates an +UARTSETUP

message with the configuration parameters of the module’s UART. For the parameters list,

see the AT+UARTSETUP command.

Syntax: AT+UARTSETUP=?

Return value: +UARTSETUP, <OK, ERROR>
