The following is a follow-up on our post Controller Area Network (CAN), SAE J1939, NMEA 2000 Wireless Module for IoT and ELD Applications.
The CAN Bus, SAE J1939 and NMEA 2000 to Bluetooth Gateway is the first product of a new series of wireless gateways for IoT (Internet of Things), ELD (Electronic Logging Devices), and other applications.
At the time of this writing, we have finished the software development of the SAE J1939 gateway, which will replace our previous SAE J1939 to Bluetooth Gateway. The functionality is 100% compatible, while the hardware has been improved through extended memory resources and optimized wireless features.
The only step remaining (before releasing the product) is the enclosure design, specifically the print layout. We expect starting production by July 2022, and a release date of beginning of August 2022. Shortly thereafter, we are planning to release the NMEA 2000 version, followed by a Standard CAN Bus gateway.
The above image represents a mockup of the final NMEA 2000 product. The CAN Bus and SAE J1939 versions will come with a DSUB9 connector, while the NMEA 2000 version utilizes an M12 5-pin connector. The enclosure is a customized version of the standard Polycase LP-21P (size 3.29 x 2.42 x 1.00 in / 83.57 x 61.47 x 25.40 mm).
For the development, we are using our JCOM.CAN.ESP32 board, which represents the core of our future wireless CAN Bus, SAE J1939, and NMEA 2000 gateways.
The onboard ESP32 processor allows further wireless connections such as BLE (Bluetooth Low Energy) and WiFi, and we will explore these features for future developments.

It was just a few weeks ago that I received some bad news. Due to the worldwide shortage of electronic components, the NXP LPC1754 processor we use for our SAE J1939 ECU Simulator with USB Port will not be available for several months, maybe even well into 2022. Consequently, it was time to rethink the design, and [...]
