With latest telelogger, it is now possible to change network settings (e.g. cellular network APN) and monitor network status for Freematics ONE+ via Freematics Controller App (through BLE). The telelogger ESP-IDF package is also updated. All Freematics ONE+ Model B and Model H shipped from now have BLE enabled firmware pre-flashed.
All of Freematics products involving GNSS have shifted to u-blox M10 solution which has better position accuracy (1.5m) and lower power consumption comparing to previous M8 solution.
From the datasheet:The u-blox M10 supports concurrent reception of four GNSS (GPS, GLONASS, Galileo, and BeiDou). The
high number of visible satellites enables the receiver to select the best signals. This maximizes the
position availability, in particular under challenging conditions such as in deep urban canyons. u-blox
Super-S (Super-Signal) technology offers great RF sensitivity and can improve the dynamic position
accuracy with small antennas or in non-line-of-sight scenarios.
The extremely low power consumption of 25 mW in continuous tracking mode allows great power
autonomy for all battery-operated devices, such as asset trackers, without compromising on GNSS
Our Easter sale is in progress! Discounts are all over the front page of our online store. While grabbing some bargains, please allow us to enjoy a prolonged Easter holiday. Orders placed from now will be shipped from 24th of April, first in first serve. Thanks for loving our products.
Telelogger ESP-IDF package integrates telelogger, Arduino library for Freematics ONE+ and ESP32 Arduino core and can be configured and built from the command-line interface of ESP-IDF, ESP32’s software development environment, giving users full control over how firmware is built for Freematics ONE+.
A configuration page dedicated to telelogger is inserted in the configuration system.
To enter the configuration system, use following command from ESP-IDF command-line.
Once configured, complete firmware image can be built with following command.
If successful, firmware can be uploaded to Freematics ONE+, running and its serial output monitored with following command.
idf.py -p [serial port] flash monitor
After being around for years, Freematics ONE+ Model B has got a refresh recently. It now comes with SIM7070G LTE-M module. LTE-M gives a longer range, lower latency, lower power consumption, full mobility and roaming support, which makes it ideal for automotive applications that operate across multiple regions. SIM7070G has global LTE and GSM network support. Comparing to SIM7600, it has no UMTS support meaning it has a limitation in areas which rely on 3G network (no 4G or 2G coverage, like some rural areas in Australia). Model H still uses SIM7600.
The Arduino library for Freematics ONE+ has been updated for application code to support both SIM7600 and SIM7070 effortlessly. Now same code can work with SIM7600 and SIM7070 without pre-configuration as cellular module is automatically identified at runtime. The telelogger (reference application code) has been significantly improved with iOS/Android app support via BLE and seamless WiFi/cellular network switching. By the way, Freematics Builder is still your best helper to use telelogger.
Whether you know or not, you can use Freematics ONE+ and Freematics ONE with our Android and iOS app named Freematics Controller. Freematics ONE+ has a BLE capable micro-controller ESP32 and Freematics ONE has a BLE module CC2541. Both of them are able to communicate with an Android or iOS mobile device wirelessly via BLE.
Freematics ONE+ and Freematics Controller App
A BLE SPP server is implemented in the Arduino library for Freematics ONE+. The datalogger code has demonstrated use of two APIs (ble_recv_command and ble_send_response) provided to perform BLE SPP communication with app. Follow the steps below to see them working.
Our ESP32 Arduino OBD Kit has been refreshed with new ESPRIT-C3. Demo code can be compiled and uploaded with Freematics Builder or Arduino IDE flawlessly. Just make sure to put libraries in place when you use Arduino IDE.
The kit is on promotional sale at the moment with a 20% discount. Grab one now!
