E0H (Self-Test Notification)

The terminal generates and sends the message in the following cases:

• The terminal will automatically perform self-test (i.e., monitor the status of components) while the software is running. If the result of the self-test changes, the terminal will send a notification report to the backend server.

• When the terminal executes the subcommand 99 of AT@RTO command from the backend server, the terminal will send a resulting report to the backend server.

• When the subcommand 99 of AT@RTO command is initiated by other channels (not backend server), the terminal will respond with a resulting report to the initiator after executing the command, and the terminal will also send the resulting report to the backend server.

Report carrying this record is a high-priority report, please see here for more information.

The frame format of a report that only carries E0H record is as follows:

For example (Total 42 bytes):
2B 00 00 2A 00 01 23 45 67 89 01 23 45 C0 31 00 0A 00 00 13 66 8E 47 F7 00 00 E0 00 78 08 5D B3 8C 80 00 00 00 00 01 23 30 24

The definitions of parts ‘Head’, ‘Reserved’, and ‘Tail’ are here.

• Event Code

  • 00H - Normal.

  • 01H - Abnormal.

• Data of Record

  It consists of one or more Data ID units.

  By default, this record contains only the data IDs listed below, which can be changed by the AT@QRC command described below.

  • Data 120 - Self-Test Status.

Configuration

The parameters related to the generation and transmission of E0H record are controlled by the following QRC command:

Example:
AT@QRC=gl601###,E0,,,1,120,012F$
+ACK:QRC,123456789012345,C031,10,0,E0,012F,20210407101530,1234$
AT@QRC?gl601###,E0,0C37$
+QRY:QRC,123456789012345,C031,10,0,1,1,E0,,,1,120,0C37,20210407101530,1234$

• Record ID

  Which record to configure. Always “E0” 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 E0H record. The characters ‘|’ are used to connect each data ID.

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