You may have noticed, with the latest code of Telelogger loaded by Freematics Builder, you will see a testing dashboard for your Freematics ONE+. The dashboard’s Javascript code is with Telelogger. It is sketch specific and can be easily altered. Just something fun and may also be a bit useful.
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.
We have just added CAN bus sniffing APIs to the Arduino library for Freematics ONE+. A simple CAN bus sniffing example sketch is also added.
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.
Freematics OBD-II UART Adapter V2.1 comes with CAN sniffing features. We are now publishing the AT commands for this purpose. The adapter’s Arduino library has also added APIs for doing CAN sniffing from Arduino sketch.
Some release notes.

We are working intensively on the next generation of Freematics ONE (namely Freematics ONE+) with Espressif ESP32 as main controller which boosts the device with 240Mhz dual core processing power, 520KB RAM, 16MB flash as well as WIFI and BLE connectivity. 2G and 3G modules are still plug-in as xBee module. There will be integrated GPS receiver while the socket for external GPS receiver is still kept and can be programmatically configured for generic digital/analog I/O as well. This will truly make the vehicle data logger the Swiss army knife for vehicle telematics project. Stay tuned!
Our Arduino Builder has just been updated. It is now built on Electron and supports compiling/uploading Arduino sketches for ESP32 (the core of upcoming Freematics products) in additional to traditional AVR based boards.
