SAE J1939 Starter Kit and Network Simulator
Our JCOM.J1939 Starter Kit and Network Simulator is designed to allow the experienced engineer and the beginner to experiment with SAE J1939 data communication without the need to connect to a real-world J1939 network, i.e., a diesel engine.
To establish a network, you need at least two nodes, which applies especially to CAN/J1939, where the CAN controller will shut down after transmitting data without receiving a response. Therefore, our jCOM.J1939 Starter Kit and Network Simulator consists of two J1939 nodes, namely our jCOM.J1939.USB, an SAE J1939 ECU Simulator Board with USB Port.
OBD-II and the Hacking of Automotive CAN Bus Networks
Let me clarify: this is not a guide to hacking automotive networks. Instead, I attempt to dismiss some common misconceptions about OBD-II and its supposed ability to control a vehicle (Spoiler alert: It cannot). As someone who has spent considerable time studying and working with CAN Bus technologies, I think it is time to set [...]

ESP32 Programming - Classical CAN to Bluetooth Gateway
In this post, I will present a CAN to Bluetooth gateway based on the ESP32 processor. The above image shows my test setup using our ESP32 WiFi, Bluetooth Classic, BLE, CAN Bus Module, a CAN-Bus Hub With 7 Ports And DC Power Connection, and the PCAN-USB Pro. As its description implies, the ESP32 module provides all necessary [...]
Discover IoT Development with ESP32 to Create Production-Grade Smart Devices
The ESP32 is a low-cost, low-power SoC (System on Chip) microcontroller with integrated WiFi and dual-mode Bluetooth. It has shipped over 100 million units as of 2018 and powers many WiFi devices on the market.

Under Development: Programmable CAN Bus to USB, Bluetooth, BLE, WiFi Gateway
For the longest time, I had resisted the idea of creating my version of a CAN-to-USB gateway, primarily due to the vast competition. A professional CAN/J1939 development requires a professional CAN-to-PC solution to monitor data traffic. I am pleased with the PEAK PCAN-USB device, as shown in the above image. However, not everybody is willing [...]
Selection Criteria and Requirements for a Telematics Gateway
The March 2023 issue of the CAN Newsletter, a CiA (CAN-in-Automation) online publication, posted an article on the selection criteria and requirements for a Telematics gateway. With cars evolving towards network technologies, OEMs (Original Equipment Manufacturers) require telematics solutions that boost seamless communication within and outside the vehicle. The device should be cloud-enabled, connectable to servers for real-time [...]
