Introduction

X_NUCLEO_IDW01M1 is a mbed library for the Wi-Fi expansion board X-NUCLEO-IDW01M1 compatible with STM32 Nucleo.

The software can be used for building Wi-Fi applications with the SPWF01SA module. It is an implementation of the NetworkSocketAPI library from mbed OS 2 ("Classic").
mbed OS 5 library can instead be found at this link.

Firmware Library

The X_NUCLEO_IDW01M1 library comes with a sample application (HelloWorld_IDW01M1v2) and a NSAPI test suite application (SpwfInterface_NSAPI_Testsv2).

This library is only supported on NUCLEO platforms and any platforms with Arduino connector. However connection to arduino needs to be done manually using 4 wires for Vdd, Gnd, Rx and Tx. Example applications have more specific details on exact connections to be used.

The features of the library are :

  • Supports mbed OS 2 ("Classic") NetworkSocketAPI
  • Supports both client sockets
  • Configuration of USART pins to be used

Class SpwfSAInterface is intended to represent the X-NUCLEO-IDW01M1 expansion board with the SPWF module.

The expansion board is basically featuring the component:

  1. a SPWF01SA Serial-to-Wi-Fi module
