I'm developing a very simple product using BLUENRG-232N. I was wondering, whether this device can function as an SPI master to just read some data from sensors, and send it over BLE ?

The documentation is also pretty confusing. It says that there are multiple GPIOs, but then in pin description telling not to connect ? ��

This might be a very good use case of the internal MCU, for building simple IoT sensors.

Probably you are looking for BlueNRG-2 instead:
