BLE 8 Click

BLE 8 Click is fully embedded stand-alone Bluetooth 5.0 Energy connectivity module, equipped with the ANNA-B112, an ultra-small, high-performing, standalone Bluetooth low energy module for easy integration of Bluetooth low energy connectivity (BLE) into various electronic devices. This module combines a high-performance Arm® Cortex®-M4 CPU microprocessor with FPU, and state-of-the-art power performance. Reliable and easy to use, BLE 8 Click is a perfect solution for development of various IoT applications, smart home applications, BLE enabled toys, advanced robotics, and other similar applications.

Click library

• Author : MikroE Team
• Date : jul 2020.
• Type : UART GSM/IOT type

Software Support

We provide a library for the Ble8 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Ble8 Click driver.

Standard key functions :

• Config Object Initialization function.

void ble8_cfg_setup ( ble8_cfg_t *cfg );

• Initialization function.

BLE8_RETVAL ble8_init ( ble8_t *ctx, ble8_cfg_t *cfg );

Example key functions :

• This function allows user to reset a module.

void ble8_reset ( ble8_t *ctx );

Examples Description

This example reads and processes data from BLE 8 clicks.

The demo application is composed of two sections :

Application Init

Initializes driver and wake-up module.

void application_init ( void )
{
    log_cfg_t log_cfg;
    ble8_cfg_t cfg;

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );

    //  Click initialization.

    ble8_cfg_setup( &cfg );
    BLE8_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ble8_init( &ble8, &cfg );

    ble8_reset( &ble8 );
    Delay_1sec( );
    
    log_printf( &logger, "Configuring the module...\n" );
    Delay_1sec( );
    
    ble8_set_dsr_pin( &ble8, 1 );
    Delay_ms ( 20 );

    do {
        ble8_set_echo_cmd( &ble8, 1 );
        Delay_100ms( );
    }
    while( ble8_process( ) != 1 );
    
    do {
        ble8_set_local_name_cmd( &ble8, "BLE 8 Click" );
        Delay_100ms( );
    }
    while( ble8_process( ) != 1 );
    
    do {
        ble8_connectability_en_cmd( &ble8, BLE8_GAP_CONNECTABLE_MODE );
        Delay_100ms( );
    }
    while( ble8_process( ) != 1 );
    
    do {
        ble8_discoverability_en_cmd( &ble8, BLE8_GAP_GENERAL_DISCOVERABLE_MODE );
        Delay_100ms( );
    }
    while( ble8_process( ) != 1 );
    
    do {
        ble8_enter_mode_cmd( &ble8, BLE8_DATA_MODE );
        Delay_100ms( );
    }
    while( ble8_process( ) != 1 );
    
    ble8_set_dsr_pin( &ble8, 0 );
    Delay_ms ( 20 );
    data_mode = 1;
    log_printf( &logger, "The module has been configured.\n" );
}
  

Application Task

Reads the received data.

void application_task ( void )
{
    ble8_process( );
} 

Note

The all possible commands, module configuration and specification can be found in the 
related documents:
    [1] ANNA-B112 System Integration Manual, document number UBX-18009821

    [3] ANNA-B112 Getting Started Guide, document number UBX-18020387 
    [4] ANNA-B112 Declaration of Conformity, document number UBX-18058993

The full application code, and ready to use projects can be installed directly from compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Ble8

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.
