Real-time Operation Command

The real-time operation command is used to control the terminal device to perform some operations in real time, such as restarting the device, clearing unsent reports, upgrading firmware, and so on.

Broadly speaking, the @Track protocol includes the following real-time operation commands:

• AT@RTO - The most commonly used real-time operation command.

• AT@UPD - Used to upgrade the firmware of the terminal device and its peripherals.

• AT@UPC - Used to update the configuration file or other files of the terminal device.

• AT@GTC - Used to obtain the entire configuration file of the terminal device.

• Query Command - Used to query a certain configuration of the terminal device.

However, when we say “real-time operation command”, we usually refer to the AT@RTO command.

Like other downstream commands, these real-time operation commands are encoded using printable ASCII characters, and the character ‘,’ is used to separate the neighboring parameter characters, for their frame format and meaning, please refer to the above hyperlinks.
