Requirements

This shield can only be used with a board which provides a configuration for Arduino connectors and defines node aliases for SPI and GPIO interfaces (see Shields for more details).

Programming

Set -DSHIELD=semtech_sx1271mb1mas when you invoke west build. For example:

# From the root of the zephyr repository
west build -b nucleo_l073rz samples/subsys/lorawan/class_a -- -DSHIELD=semtech_sx1276mb1mas
