▶ 0: flow control is not enabled
▶
1: enable both RTS and CTS
Notes
• AT+UART_DEF? will return the actual value of UART configuration
parameters, which may have allowable errors compared with the
set
value because of the clock division.For example, if the UART
baud
rate is set as 115200, the baud rate returned by using command
AT+UART_CUR? could be 115273.
•
The configuration changes will be saved in the user parameter area
in
the flash, and will still be valid when the chip is powered on ag
ain.
