BLE 9 click

BLE 9 Click is a fully embedded stand-alone Bluetooth 5.2 Energy connectivity module, equipped with the EFR32BG22 Series 2 Modules, 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®-M33 CPU microprocessor with FPU, and state-of-the-art power performance. Reliable and easy to use, BLE 9 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 : Dec 2020.
  • Type : UART type

Software Support

We provide a library for the BLE9 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 Ble9 Click driver.

Standard key functions :

Example key functions :

Examples Description

This example demonstrates the use of BLE 9 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 and performs the click default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
Delay_ms( 100 );
// Click initialization.
ble9_cfg_setup( &cfg );
BLE9_MAP_MIKROBUS( cfg, MIKROBUS_1 );
ble9_init( &ble9, &cfg );
Delay_ms( 1000 );
log_printf( &logger, "Creating advertising point...\n" );
Delay_ms( 100 );
ble9_adv_create_id ( &ble9 );
log_printf( &logger, "Starting module advertising...\n" );
Delay_ms( 100 );
log_printf( &logger, "The module has been configured.\n" );
Delay_ms( 100 );
}

Application Task

Reads and processes all incoming data and displays them on the USB UART.

void application_task ( void )
{
ble9_process ( &ble9 );
if ( app_buf_len > 0 )
{
for ( uint16_t cnt = 0; cnt < app_buf_len; cnt++ )
{
log_printf( &logger, "%.2X ", ( uint16_t ) app_buf[ cnt ] );
}
ble9_clear_app_buf( );
}
}

Note

For more information on the chip itself and the firmware on it,
please visit the following page:
    [1] https://docs.silabs.com/bluetooth/3.1
  • Take into condideration that the library itself is designed to work with GSDK version 3.1.0 If you wish to use a different version of firmware, take into consideration that some functions might not work.
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.Ble9
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.
