Freematics Vehicle Data Logger is a hardware device capable of logging and transmitting a car’s mechanic data, motion data and GPS coordinates over Internet (2G/3G/WIFI).
In addition to real-time monitoring, through data mining, some useful information can be extracted for car rental/sharing industry.
We have been working on a new 3G WCDMA/GSM xBee module for Freematics ONE vehicle data logger. It’s based on SIMCOM SIM5360E. Comparing to former SIM800L based GSM/GPRS xBee module, the new comer will provide a faster data link and more importantly continue to work in regions where 2G network is about to be shut down (like Australia).
Today we are happy to announce the release of the new module as a new option for Freematics ONE, which can be ordered and shipped with Freematics ONE right away. Head to our online store to place your order now.
Freematics ONE now comes with MPU-9250 MEMS sensor! The supporting Arduino library and example sketches (in Github) have been updated for 9-axis MEMS data access. To order Freematics ONE with MPU-9250, make sure to choose MPU-9250 in MEMS option on the order page.
Code clip of accessing MEMS data.
int acc[3]; // accelerometer data
int gyr[3]; // gyroscope data
int mag[3]; // magnetometer data
int temp; // device temperature (in 0.1 celcius degree)
if (memsRead(acc, gyr, mag, &temp)) {
// success

MegaLoggerHD is a reworked version of MegaLogger which targets at the new Telematics Shield with 3.5″ LCD of 480×320 resolution designed for our OBD-II Telematics Advanced Kit. It supports both Freematics OBD-II I2C Adapter and UART Adapter V2 (by switching in config.h). The code has just been committed to github. This is the initial revision. Subsequent improvements will be followed.

The new 3.5″ LCD shield for our Telematics Advanced Kit is released! This time we teamed up with DFRobot to bring our fans higher quality hardware design and build.
The new hardware can be ordered now with the kit. Click here to head for the online store.
Freematics ONE is an Arduino UNO in the form of OBD-II dongle with an xBee socket inside that allows Freematics ONE to get different wireless communication capability by various xBee modules. Today let’s show how a ESP8266 WIFI bee module gives Freematics ONE WIFI connectivity.
To communication with xBee module in the socket, it is recommended to use xBee APIs (function names begin with xb) provided by our library. This test sketch initiates ESP8266, joins a WIFI network (with correct SSID and password set) and communicates with a remote server with HTTP GET. It runs like following. Here is ESP8266 AT command set for a reference.
Update (9 May)
A more comprehensive and well commented Arduino sketch for Freematics ONE with ESP8266 WIFI module is available here.
The hardware development of Freematics ONE is finalized and first batch of 500pcs has been manufactured and is now being tested. Since many have expressed interest in the new product, we hereby publish some close look pictures and details of it.
If you are a developer, you may have interest to take a look at the open-source reference firmware (a.k.a sketch) that is still being developed.
