SP1ML-915 custom firmware

I'm wanting to load a custom firmware onto the SP1ML-915, as I'd like to implement abilities I can't get through the existing AT command set.

Where can I find documentation about how the STM32L151RB is connected to the Spirit1 chip? i.e. which spi on what pins?

Also, does STM32CubeMX offer any help in setting up a base for a this type of firmware? Would appreciate any pointers, as I'm fairly new to all of this.

I'm also interested about the possible answers to this question.

That would be a huge benefit to use the stm32 inside the module for our own application (gather some simple acquisitions from a sensor) rather that including another mcu only for that purpose.

Thank you.

Simply use the P2P example included in STM32CubeExpansion_SUBG1_V1.0.0.

Then you should know that:

PA5 ------> SPI1_SCK

PA6 ------> SPI1_MISO

PA4 ------> SPI1_NSS

PA7 ------> SPI1_MOSI

PA1 ------> SPIRIT_SDN

PC4 ------> SPIRIT_IRQ0
