<parity>
<flow control>
• This configuration will also store the baud rate as the default rate in the
user parameter area in the Flash for boot up.
Notes
• Flow control needs hardware support: MTCK is UART0 CTS and MTDO is UART0
RTS.
8. AT+UART_CUR – current UART configuration
This command sets the current UART configuration; it does not write to the flash device. Hence there
is no change in the default baudrate.
AT+UART_CUR=<baudrate>,<databits>,<stopbits>,<parity>,<flow control>
Example
AT+UART_CUR=115200,8,1,0,3
Response
OK
<baudrate>
<databits>
<stopbits>
Parameters
<parity>
<flow control>
• This configuration will NOT be stored in the flash; unlike the AT+UART
command.
Notes
• Flow control needs hardware support: MTCK is UART0 CTS and MTDO is UART0
RTS.
