Library Description

The library contains a generic command parser, adopted for AT command based modules.

Key functions

wifinina_cmdSingle - Sends provided command to the module

wifinina_setHandler - Handler assignation to the provided command

wifinina_modulePower - Turn on module

Examples Description

The demo application is composed of three sections:

• System Initialization - Initializes all necessary GPIO pins, UART used for the communication with GSM module and UART used for information logging.
• Application Initialization - Initializes driver, power on the module, and it enables hardware flow control. Commands sent after initialization are checking communication with the module, disabling echo and checking the firmware version. Finally, a command for WiFi networks in area scan is sent.
• Application Task - Running core state machine necessary for successful message parsing.

void applicationInit()
{
// MODULE POWER ON
    wifinina_hfcEnable( true );
    wifinina_bootMode( true );
    wifinina_modulePower( true );

// MODULE INIT
    wifinina_cmdSingle( "AT" );
    wifinina_cmdSingle( "ATE0" );
    wifinina_cmdSingle( "AT+CGMR" );

// SCAN NETWORKS
    wifinina_cmdSingle( "AT+UWSCAN" );
}

Additional Functions :

Timer initialization, timer ISR, and default handler.
 

Other MikroElektronika libraries used in the example:

• UART
• String
• Conversion

Additional notes and information

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.
