-To compile Nucleo X WiFi configuration, you need to tell mbed NOT to compile mesh files for example. To do that, set up a `.mbedignore` file. An example file is available in the `configs` folder.
+Currently, two STM WiFi expansion boards are available:
+- `X-NUCLEO-IDW01M1`, which is the Morpho form-factor board, and
+- `X-NUCLEO-IDW04A1`, which is the Arduino form-factor board.

-If you have issues with the `IDW04A1` board you might have to define also a macro `IDW04A1_WIFI_HW_BUG_WA`. This can be added to the same `.json`file to the `macros:` section.
