calamp

The protocol for CalAmp GPS tracking devices.

Below is the list of parameters that can appear in the messages received by the channel via calamp 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".
