this page for debug set temperature and analog input threshold and RTC clock

   
This is write RTC clock example.

for example, set RTC clock:
we set 2022-03-08  21:38:00 to KC868-COLB

send command is:
5E 01 32 C0 06 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 16 03 08 15 26 00

0x5E 01 : begin byte, never change it.
0x32 C0: command type
0x06 00: message length  now the message is "16 03 08 15 26 00"  total 6 bytes
0x00 ... ... 00  38 of 0x00 retain bytes, not chang it.
0x16 03 08 15 26 00 is year,month,date, hour,minute,second
0x16=22 use two last number of year, default begin with20 so year=2022
0x03=03
0x08=08
0x15=21
0x26=38
0x00=00
