This protocol is used by ATrack GPS tracking devices. Please also read our guide on how-to connect ATrack device to flespi in few mouse clicks.

In order to connect Teltonika to Wialon or other platform via flespi please read this article.

Below is the list of parameters that can appear in the messages received by the channel via atrack protocol. In most parameters, the name consists of tags split by dots: tag1.tag2.tag3.tag4... Each tag defines a certain area of an application, e.g. any parameter that contains mileage data has the 'mileage' tag in the name and any parameter related to fuel control contains the 'fuel' tag. By default JSON fields of the message received by a channel via this protocol can only contain the below-specified parameters. Any additional parameter will be prefixed by the "custom" tag, e.g. "custom.unspecified-name".

Below is the list of commands that can be sent to devices to change their configuration or to send signals to various outputs. When sending a command you can specify the transport type defining how the command will be delivered - the address parameter can take values connection (via network connection once the device goes online), sms (via SMS message), push (via PUSH notification). A comprehensive format of each command with all possible parameter values, parameter types, default values, etc. can be found in the REST API documentation in your account.

Title Name Description Properties
AT Command at Send AT Command cmd: Command
Set output 2 to be ON for 3 seconds, OFF for 2 seconds, for 5 times
