Download the Latest Before You Start

Always use the latest versions of the module firmware and an up-to-date example code set.

Go to the Wi-Fi module’s page www.parallax.com (search for 32420S) and click the Documents and Downloads section.
Download the most recent (highest version number) 32420-Parallax-ESP…zip.
Unzip to a folder and make sure the words Parallax ESP and the version number are in the folder name.
