    ○ 5:5 bit data bits

    ○ 6:6 bit data bits

    ○ 7:7 bit data bits

    ○ 8:8 bit data bits

  • <stopbits>: Stop bits

    ○ 3: Enable both RTS and CTS simultaneously

Description：

  • The query command returns the actual value of the UART configuration parameter, which may differ slightly from the set value due to clock division.
  • This setting is not saved to flash.
  • To use hardware flow control functions, it is necessary to connect the CTS/RTS pins of the device. Currently, the MX1510 series modules do not support flow control

Example:

11. AT+UART_DEFFunction：Configure the current temporary configuration of UART and save it to flash.Query Command：AT+UART_DEF?Response：+UART_DEF:,,,,OKParameter：Please refer to AT+UART_CUR set command parameter.Set Command：AT+UART_DEF=[,,,,]Response：OKParameter：Please refer to AT+UART_CUR set command parameter.Description：This setting is saved to the KV partition of flash. Still valid when the device is powered on againThe Query Command reads the parameters saved in the KV partition, which may be different from the current serial port parametersDemo：12. AT+UARTPACKFunction：The packaging and processing method of serial port data.Query Command：AT+UARTPACK?Response：+UARTPACK:OKParameter：Please refer to set command parameter.Set Command：AT+UARTPACK=Response：OKParameter：:  UART data packaging processing method, please refer to the work mode switching content on this page for details.○ 0: RAW DATA mode, when the data reaches its maximum length or has not received new data for a period of time, the data is packaged and sent to a predefined network channel. The received network data is also directly sent to the serial port○ 1: AT mode: Parse data in the format of the AT command (starting with AT and ending with CR-LF), and send it to the AT subsystem for processing. In this mode, the echo function of the AT command is automatically activated.○ 2: AUTO mode: If the first two bytes are "AT", the data is processed in AT mode; otherwise, it is packaged and processed in RAW DATA mode.Demo:AT+CIPMODE=0

OK
+WRITE,5:Hello //Output in the form of AT events

AT+CIPMODE=1

OK
Hello	//Output in RAW data format
