Atrack AX7

rostand Please clarify the model of equipment Atrack.
For OBD2 trackers (for example AX7) there is a problem with calibration of accelerometer. That's why it is rather complicated to analyze eco driving parameters.

There are two possible ways to analyse driving behaviour.

1) You can add "%GV" parameter by AT$FORM command.
Atter that your devices will start to send %GV parameter and you will see parameters "gx", "gy", "gz" in messages in Wialon, which will contain acceleration value for an appropriate axis (x, y or z).
In this case you can indicate appropriate settings on the Eco-Driving tab of the unit properties dialog on the basis of parameters "gx", "gy" and "gz":

2) It is also possible to configure Atrack devices to send specific report ID when some event happens (for example, acceleration/deceleration).
In this case you will see appropriate "report_id" parameter in messages in Wialon and you will be able to use it for Notifications, for example. It is better to request Atrack support about configuring specific events.
