How do I set up a WiFi APN with EC-200U-EU?

According to the documentation, it’s possible to configure a WiFi access point using the EU-200C module AP Mode - QuecPython. I’m encountering an issue when importing the module related to the ‘SLIP’ on (Serial Line Internet Protocol) package related to “usr.WLAN import ESP8266”. It seems that this package is not available in my firmware. Can you help me find a solution? AP Mode - QuecPython
