DFR0575 out of date core?

Trying to use the ESP32 Beetle (DFR0575) to write data to Influx. 

Adding only the library (without any other code), listed by Influx (InfluxDB Client for Arduino) results in an compiling error. That error points to probably an outdated ESP32 core (required 2.0.2 or higher). 

What ESP32 core is the http://download.dfrobot.top/FireBeetle/package_esp32_index.json link pointing to? Could that point to an outdated core?
