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.
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.
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.
Some release notes.
- Binaries are built and tested on Ubuntu Linux 17.04
- Electron is contained and used as GUI engine
- Port 8080 and 8081 are used for TCP and UDP by default
- You may need to make privilege settings if not run as root
- Data is stored in data directory by default
- GUI and server are launched together by run.sh shell script

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!
