3.2.8. AT+UART_CUR—Current UART Configuration, Not Saved in Flash
Set Command
Parameters
Espressif
AT+UART_CUR=<baudrate>,<databits>,<stopbits>,<parity>,<flow control>
Response
OK
• <baudrate>: UART baud rate
• <databits>: data bits
‣ 5: 5-bit data
‣ 6: 6-bit data
‣ 7: 7-bit data
‣ 8: 8-bit data
<stopbits>: stop bits
•
‣ 1: 1-bit stop bit
‣ 2: 1.5-bit stop bit
‣ 3: 2-bit stop bit
• <parity>: parity bit
‣ 0: None
‣ 1: Odd
‣ 2: Even
• <flow control>: flow control
‣ 0: flow control is not enabled
‣ 1: enable RTS
‣ 2: enable CTS
‣ 3: enable both RTS and CTS
1. The configuration changes will NOT be saved in flash.
2. The use of flow control requires the support of hardware:
Notes
‣ IO15 is UART0 CTS
‣ IO14 is UART0 RTS
3. The range of baud rates supported: 80 ~ 5000000.
