Requirements
This shield can only be used with a board that provides a configuration for Arduino connectors and defines node aliases for UART and GPIO interfaces.
An NBIOT SIM, NanoSIM format, should be plugged in the SIM card holder to enable modem network connection.
Build and Programming
To compile, set --shield st87mxx when you invoke west build.
Then compile a sample, e.g.,
west build -b your_board --shield st87mxx samples/net/sockets/http_client
west flash
