A short description is here.
The SW for CUBE is: X-CUBE-SUBG1
X-CUBE-SUBG1 is an expansion software package for STM32Cube.
Quick start guide - How to use the P2P example (present into the X-CUBE-SUBG1) on the X-NUCLEO-IDS01A4 ( SPSGRF-868 or SPIRIT1) and NUCLEO-L053R8
The software runs on the STM32 and includes drivers that recognize the
Sub-1 GHz RF communication for SPIRIT1 modules SPSGRF (SPSGRF-868 or
SPSGRF-915). The expansion is built on STM32Cube software technology to
ease portability across different STM32 microcontrollers.
The software comes with examples of implementation of P2P and WM-Bus communication protocols, running on a SPIRIT1 module SPSGRF expansion board (X-NUCLEO-IDS01A4 or X-NUCLEO-IDS01A5) when connected to a NUCLEO-F401RE or NUCLEO-L053R8.
WM-Bus communication protocol is available for X-NUCLEO-IDS01A4 only.
It is also available the: X-NUCLEO-IDS01A5
Sub-1 GHz RF expansion board based on the SPSGRF-915 module for STM32 Nucleo
