Telelogger is one of the reference firmwares for Freematics ONE+ which turns the hardware into a vehicle data logger and telemeter working with Freematics Hub. Recently the code got a major upgrade, with data collection/logging and network transmission implemented as separate tasks (threads), linked with a sizable circular buffer, so network outrage will no longer block data logging and collected data can be kept for a while for later transmission. Other benefits include faster startup and higher data throughput. Freematics ONE+ users feel free to upgrade from code in github.

Freematics Hub Service has been online for a while as a free cloud service for Freematics ONE+ developers to quickly test the connected vehicle telemetry hardware. It is based on the open-source Freematics Hub server software and allows users to easily access to live data collected from vehicle remotely as well as to review and analyze vehicle’s history routes and trip data. Freematics Hub provides REST API for access to live/history vehicle data. Freematics Hub Service provided with a set of web-based UI built on the API.
Home Screen
The home page of Freematics Hub Service consists of shortcuts to various features. A blank in the middle is where user enters device ID or E-mail (with pre-created account). It is most straight-forward to use device ID to start. The device ID is a unique string to identify a device and can be found in the serial output of Freematics ONE+ running telelogger. You can tick “Save My Info” to make it persistent with cookie for easy access next time. With that, click/tap on one of shortcut buttons one of below features.
Live Data – to remotely view real-time vehicle data and location
Trip Browser – to review vehicle’s history routes and data
Parking Meter – a simple parking location and time display (best view on mobile phone)

CAN sniffing is interesting if you are have some insider information or good at reverse engineering, so some vehicle data outside the scope of standard OBD-II PIDs can be extracted.
Another product supporting CAN sniffing at the moment is Freematics OBD-II UART Adaper V2.1. This post has some information about the AT commands for CAN sniffing.

We now supply external GNSS antenna (SMA interface) for SIM5360 cellular module when you order Freematics ONE+. Using SIM5360’s internal GNSS is more cost-effective than standalone M8030 solution when 1Hz update rate and slightly longer satellite locking time are acceptable.
