Freematics ONE+ HD will be the next variant of ONE+ targeting heavy duty vehicles (trucks, buses) with HD-OBD (Heavy Duty OBD) connector and J1939 support.
The library for ONE+ has been updated and testing sketch included for J1939 data monitoring.
We have just released a minor update for the GUI software of Freematics OBD-II Emulator. In this release, emulator’s VIN (persistent) is automatically read and displayed on the GUI. There are some other bug-fixes for DTC setting. Please note the GUI is now built with Visual Studio 2019 so there is no more Windows XP compatibility.
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.
