10.5. Running a web page on the radio module
The Calypso radio module offers a secure file system to store files in the radio module. In
combination with the HTTP(S) server function, a custom web site can be run on the module.
This chapter describes how to do so by loading a simple html file (see Code
1
) to the mod-
ule’s flash memory. Furthermore the customization of the web site access is demonstrated
in the subsequent sections.
