| 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 |
| :ref:`shields` for more details). |
| |
| Programming |
| *********** |
| |
| Set ``-DSHIELD=semtech_sx1271mb1mas`` when you invoke ``west build``. For |
| example: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/subsys/lorawan/class_a |
| :board: nucleo_l073rz |
| :shield: semtech_sx1276mb1mas |
| :goals: build |
