AT+UART_CUR – current UART configuration
This command sets the current UART configuration, it does not write changes to the flash. Hence
there is no change in the default baud rate.!
AT+UART_CUR=<baudrate>, <databits>, <stopbits>, <parity>, <flow control>
Example
AT+UART_CUR=115200, 8, 1, 0, 3
Response
OK
Parameters
<baudrate>
Baudrate range: 110 to 115200*40 (4.608 Mega)
<databits>
5: 5 bits data!
6: 6 bits data!
7: 7 bits data!
8: 8 bits data
<stopbits>
1: 1 bit stop bit!
2: 1.5 bit stop bit!
3: 2 bit stop bit
<parity>
0: None!
1: Odd!
2: EVEN
<flow control>
0: disable flow control!
1: enable RTS!
2: enable CTS!
3: enable both RTS and CTS
Notes
•
This configuration will NOT store in the flash.
•
Flow control needs hardware support: MTCK is UART0 CTS and MTDO is
UART0 RTS.
