Ai-WB2-12F click

Ai-WB2-12F Click is a compact add-on board for easy integration into the Internet of Things (IoT) and smart home applications. This board features the Ai-WB2-12F, a WiFi and BLE module from Ai-Thinker Technology, powered by the BL602 chip supporting WiFi 802.11b/g/n and BLE 5.0 protocols.

Click library

  • Author : Stefan Ilic
  • Date : Nov 2023.
  • Type : UART type

Software Support

We provide a library for the Ai-WB2-12F Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Ai-WB2-12F Click driver.

Example Description

This example demonstrates the use of Ai-WB2-12F click board by processing

the incoming data and displaying them on the USB UART.

The demo application is composed of two sections :

Application Init

Initializes the driver, tests the communication, and after that restarts the device, and performs example configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
aiwb212f_cfg_t aiwb212f_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
aiwb212f_cfg_setup( &aiwb212f_cfg );
AIWB212F_MAP_MIKROBUS( aiwb212f_cfg, MIKROBUS_1 );
if ( UART_ERROR == aiwb212f_init( &aiwb212f, &aiwb212f_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
aiwb212f_process( );
aiwb212f_clear_app_buf( );
aiwb212f_hw_reset( &aiwb212f );
error_flag = aiwb212f_rsp_check( AIWB212F_RSP_READY );
aiwb212f_error_check( error_flag );
// Check communication
error_flag = aiwb212f_rsp_check( AIWB212F_RSP_OK );
aiwb212f_error_check( error_flag );
// Restart device
error_flag = aiwb212f_rsp_check( AIWB212F_RSP_READY );
aiwb212f_error_check( error_flag );
aiwb212f_configure_for_example( );
log_info( &logger, " Application Task " );
}

Application Task

Depending on the selected demo example, it sends a TCP/UDP echo server message and receives it or

creates BLE Client which receives the messages from the connected device.

void application_task ( void )
{
aiwb212f_example( );
}

Note

We have used the BLE Scanner Android application for the BLE Example test

and you can find it at the link: https://play.google.com/store/apps/details?id=com.macdom.ble.blescanner

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.AiWB212F

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. UART terminal is available in all MikroElektronika compilers.
