Trying to setup a Freematics One+ for use with traccar and getting this error when attempting to build with Arduino Builder.

Compiling datalogger.ino.cpp...
C:\Users\user\AppData\Local\Temp/ArduinoBuilder/datalogger.ino.cpp: In function 'void showSysInfo()':
C:\Users\user\AppData\Local\Temp/ArduinoBuilder/datalogger.ino.cpp:727:36: error: 'esp_spiram_get_size' was not declared in this scope
Error compiling source code.

It happened to me as well but on the datalogger example. I commented the "esp_spiram_get_size" function call inside "showSysInfo()" and it worked for me.

Even with the datalogger example, I had the same problem. To fix that, I commented out the call to "esp_spiram_get_size" inside "showSysInfo()" and it ran well.

I believe esp_spiram_get_size is an updated API provided by recent ESP32 Arduino core. It seems you might be using an older core.
