for example.
AT+ wlanconnect = calypso , , P2P_PBC , , , ,
In case of the group owner, the output is as follows.

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.
< html >

< meta h t t p − e q u i v = " Content − Type " content = " t e x t / h t m l ; c h a r s e t = u t f − 8" >
