In case anyone interested, the command (sent via UART) for settings the SoC parameter in the Daly BMS (this also writes the date/time), is as follows:



A5 40 21 08 - the usual header; 0x21 is the command-id to write SoC and RTC
160C0D151D27 - 6 bytes for the date/time. YY-MM-DD HH:MM:SS. This example 12/13/2022 9:29:39
01 2C - this sets the SoC. This example: 300/10 = 30%)
C3 - checksum as normal

(bytes in hex)

This is not mentioned in the Serial protocol dokumentation.
