Library Description

The library contains a basic functions for using WiFi 11 click.

Key functions:

• void wifi11_set_conect_to_ap( char *username, char *password ) - Connect to AP
• void wifi11_send_command ( uint8_t *cmd ) - Send command

Examples description

The application is composed of three sections :

• System Initialization - Initializes UART module and all necessary GPIO pins
• Application Initialization - Initializes driver module and stert sends AT comands.
• Example : TCP client - Please, before the uploaded program you should write network parameters and TCP server parameters.

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
