1. The general data format for sending/receiving is as follows

CHKSUM = ADDR + SN + CMD + DAT1 + DAT2 + DAT3 + DAT4

Command assembly format for sending (19 characters): '<' + 'T' + 2-digit ADDR + 2-digit SN + 2-digit CMD + 2-digit DAT1 + 2-digit DAT2 + 2-digit DAT3 + 2-digit DAT4 + 2-digit CHKSUM + '>'

Command assembly format for receiving (19 characters): '<' + 'F' + 2-digit ADDR + 2-digit SN + 2-digit CMD + 2-digit DAT1 + 2-digit DAT2 + 2-digit DAT3 + 2-digit DAT4 + 2-digit CHKSUM + '>'

📢  Important

Format description of send/receive commands with a data block (CMD = 0xE0 or 0xE1)

The last byte of the data block is the checksum, calculated as the sum of all bytes in the data block. The data block length (DAT3 and DAT4) includes the checksum.

All data blocks are represented in JSON format. The specific fields are described with each command.

📢 Notes: To specify the language, include the {"language":1} field:

• 1: Chinese
• 0: English

Currently, only Chinese and English are supported.

Example of a command: JSON data block + CHKSUM {"statusType":1,"statusValue":10,"language":1}b
