On the Arduin MRK-WIFI101 is a Ublox Nina module for enabling WiFi Support. I want to design my own circuit and use the Nina Module with another Processor. When looking at the schematic, i discovered that alot of pins are connected to the Nina Module. As far as i've seen there is UART, SPI and I2C there, but i'm sure you could use just one of the Interfaces...
I discovered that there is an arduino sketch that allows to update the firmware on the Nina Module.
Does anyone here have knowlege what the minium pins are for operating this module? The Processor should just communicate with the module for WIFI. GPIO functionality is not needed. For updating the firmware i can use a programmer or something else.
Is the library communicating by UART or SPI?
Thanks for any info..
