You may have received a white label unit. Except for the label, everything else is same.

You need to build with ESP-IDF and enable PSRAM and RTC through menuconfig.

As I have replied your email, you have ordered the unit with wrong cellular module. SIM5360A and SIM7600A-H are for North America (which the 'A' indicates).

You need to write your own code. Please note not powertrain related codes can be read.

Currently DTC codes are not submitted to traccar server.

Software serial is only reliable at 9600bps and the adapter requires 38400bps or higher. I suggest you communicating with PC via software serial or use Arduino Mega or our Freematics Esprit dev board. Both have multiple hardware serial. https://freematics.com/store/?route=product/product&product...

Actually I am working on this to make wifi optional and re-connectable. Auto uploading on connection of wifi is a useful feature but its implementation is not in my list so you are on your own.

Be aware you can't use USB serial as Arduino's hardware serial is connected to the adapter.

Use the latest ESP32 Arduino package in PlatformIO now like following [env:esp32dev] platform = https://github.com/platformio/platform-espressif32.git#feature/arduino-upstream platform_packages = platformio/framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git#2.0.4 board=esp...

Neither model B or model H supports J1850.
