Application in car rental/sharing industry

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.

Freematics ONE now comes with 3G xBee module

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

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 released

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.

Using ESP8266 WIFI bee with Freematics ONE

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.
