ODO (Odometer Settings)¶
The AT@ODO command is used to set the parameters related to the odometer function.
The terminal calculates the mileage according to the GNSS positioning data when the vehicle is ignition on. Due to the instability of GNSS signal and other reasons, there may be some deviations in this calculation method.
Example:
AT@ODO=gv500cna,1,0,,012F$
+ACK:ODO,123456789012345,8203,3,0,,012F,20210407101530,1234$
AT@ODO?gv500cna,,0C37$
+QRY:ODO,123456789012345,8203,3,0,1,1,1,0,,0C37,20210407101530,1234$

Mode
0 - Disable. The terminal will not calculate mileage.
1 - Enable. The terminal will calculate the mileage.
Note: If configured as Mode 0, the terminal will clear the Total Mileage (refer to Data 31) and the Current Mileage (refer to Data 32).
Initial Mileage
The initial value for calculating the total mileage. This parameter is only valid in Mode 1.
Note: When the terminal receives the AT@ODO command, it checks the Initial Mileage parameter: Only if this parameter is not empty and its value is different from the value stored in the terminal, the terminal will perform the operation “Initialize the Total Mileage (refer to Data 31) and clear the Current Mileage (refer to Data 32)”.
