The highlight of this update is the support for RISC-V based ESP32-C3. With more products based on this new SoC rolling out soon, Freematics Builder has got a refresh just in time. Meanwhile, we have ESPRIT-C3 which is a ESP32-C3 based dev board for you to play with.
This release package contains Telelogger, FreematicsPlus library and ESP32 Arduino core 2.0.0 in form of ESP-IDF component. It allows developers to build for and upload to ESP32/ESP32-C3 based Freematics products from ESP-IDF command line environment to get the best of the versatile build system.
Download and read instructions from github.
This update includes a bugfix for KWP2000 protocol. Please download the latest GUI software package to update firmware. Please note the update is only applicable to emulator without J1850 protocols.
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.
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.
