This message is used to report the harsh behavior alarm to backend server. About the harsh behavior alarm detection, please see the AT@HBM command.

The frame format of a report that only carries 72H record is as follows:

For example (Total 68 bytes):
2B 00 00 44 00 01 23 45 67 89 01 23 45 00 00 00 1B 00 00 2D 64 F9 AA F6 00 00 72 01 80 8C 09 01 02 58 00 00 00 00 00 00 52 16 09 F9 20 A8 E1 FF 2D C0 96 5F 17 9D A0 01 7D 0A 00 25 00 01 B3 0C 01 23 90 24

• Record ID

  Which record to configure. Always “72” here.

• Action

  • Empty - No change the data IDs in the terminal. If this field is empty, the ‘Data IDs’ field will be ignored.

  • 0 - Append the data IDs carried in the ‘Data IDs’ field to the terminal.

  • 1 - Replace the data IDs in the terminal with the data IDs carried by the ‘Data IDs’ field.

  • 2 - Clear the data IDs carried in the ‘Data IDs’ field from the terminal.

  Note: In particular, it always will be 1 when reading this field.

• Data IDs

  The data IDs contained in the 72H record. The characters ‘|’ are used to connect each data ID.

  For example, “2|88” means Data 2 (Device Name) and Data 88 (SIM Card).
