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.
Freematics OBD-II Emulator GUI updated with newly added control interface for OBD Readiness Monitors which allows you to control what kind of OBD readiness results your OBD-II device can fetch from Freematics OBD-II Emulator.
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.
Today we dispatched our 2,000th shipment. It has been just 2 years for Freematics to grow from a hobby project about OBD-II and Arduino exhibited on a stall at Maker Faire to a series of products shipped worldwide on daily basis. A big thank you to all our customers around the globe for your trust! It just feels so good to create something that is needed by many people. The most exciting thing is not about the past but about the new ideas we have on our new products. Just can’t stop moving forward!
As you may or may not know, we are working intensively on the next generation of Freematics Vehicle Data Logger.
