Return value
[C1_PARITY] Value is: <parity>\r\n
6.4.4.6
Serial flow control (AT+C1_SER_C)
Command format
Parameters
Usage
AT+C1_SER_C=<c>\r\n
<c>
0: None (default)
1: Hardware flow control
Define new value
AT+C1_SER_C?\r\n
Query current value
Return value
[C1_SER_C] Value is: <c>\r\n
This command activates the hardware flow control. This could improve the data accuracy for high speed
transmission. Note: If turn on this function, the counter serial device also need to turn on this function.
6.4.4.7
Clear serial buffer if connect (AT+C1_BUF_CLS)
Command format
Parameters
Usage
AT+C1_BUF_CLS=<class>\r\n
<cls>
0: Do not clear the serial port buffer after establishing connection
(default)
1: Clear data in serial buffer after establishing connection
Define new
value
AT+C1_BUF_CLS?\r\n
Query current
value
Return value
[C1_BUF_CLS] Value is: <cls>\r\n
If there is disconnection during data communication, serial buffer may still contain data which haven’t send out.
This command could handle usage of those remaining data in serial interface after reconnection.
6.4.4.8
Data packaging size (AT+C1_SER_LEN)
Command format
Parameters
Usage
AT+C1_SER_LEN=<len>\r\n
<len>
The length of the data package, value range: 0 ~ 2048
bytes, default: 0 (Disable data packaging by size )
Define new value
AT+C1_SER_LEN?\r\n
Query current value
Return Value
[C1_SER_LEN] Value is: <len>\r\n
When receiving data from serial port, this value defined the length of single data package each time.
6.4.4.9
Data packaging time (AT+C1_SER_T)
Command format
Parameters
Usage
AT+C1_SER_T=<time>\r\n
<time>
Data packaging by time, value range: 0 ~ 60000, unit:
ms; default: 0 (disable data packaging by time)
Define new value
AT+C1_SER_T?\r\n
Query current value
Return value
[C1_SER_T] Value is: <time>\r\n
When receiving data from serial port, this value defined the time frame for sending the data in buffer.
