BLE 10 Click

BLE 10 Click is a compact add-on board that provides BT/BLE connectivity for any embedded application. This board features the PAN1780-AT, a Bluetooth® 5 Low Energy Module based on Nordic's nRF52840 single-chip controller from Panasonic.

Click library

  • Author : Stefan Filipovic
  • Date : Sep 2021.
  • Type : UART type

Software Support

We provide a library for the BLE10 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 BLE10 Click driver.

Standard key functions :

Example key functions :

  • ble10_set_device_name This function sets the local device name.
    err_t ble10_set_device_name ( ble10_t *ctx, char *dev_name );
  • ble10_factory_reset This function factory resets the device.
  • ble10_get_temperature This function executes get temperature command which returns the current temperature of the module's internal temperature sensor.

Example Description

This example reads and processes data from BLE 10 clicks.

The demo application is composed of two sections :

Application Init

Initializes the driver, then performs a factory reset and sets the local device name.

void application_init ( void )
{
log_cfg_t log_cfg;
ble10_cfg_t ble10_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
ble10_cfg_setup( &ble10_cfg );
BLE10_MAP_MIKROBUS( ble10_cfg, MIKROBUS_1 );
err_t init_flag = ble10_init( &ble10, &ble10_cfg );
if ( UART_ERROR == init_flag )
{
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
ble10_default_cfg ( &ble10 );
ble10_process( );
ble10_clear_app_buf( );
app_buf_len = 0;
app_buf_cnt = 0;
log_printf( &logger, " - Factory Reset -\r\n" );
ble10_factory_reset ( &ble10 );
ble10_display_rsp ( EVT_RESET );
log_printf( &logger, " - Set Device Name -\r\n" );
ble10_display_rsp ( RSP_OK );
log_info( &logger, " Application Task " );
}

Application Task

Logs all the received events/responses on the USB UART. Then checks if there's a specific command string (defined by the GET_TEMP_COMMAND macro) received from the GATT Server, and if so, it executes temperature reading command and logs the results.

void application_task ( void )
{
ble10_process( );
if ( app_buf_len > 0 )
{
Delay_ms ( 100 );
ble10_process( );
for ( int32_t buf_cnt = 0; buf_cnt < app_buf_len; buf_cnt++ )
{
log_printf( &logger, "%c", app_buf[ buf_cnt ] );
}
if ( strstr( app_buf, EVT_GATT_VAL ) )
{
char get_temp_cmd[ ] = GET_TEMP_COMMAND;
const char * __generic msg_ptr = strrchr ( app_buf, ',' ) + 1;
uint8_t msg_len = *( msg_ptr - 2 ) - 48;
if ( msg_len == strlen ( get_temp_cmd ) )
{
char get_temp_hex[ 64 ] = { 0 };
uint8_t get_temp_hex_chr[ 3 ] = { 0 };
uint8_t cnt = 0;
for ( cnt = 0; cnt < strlen ( get_temp_cmd ); cnt++ )
{
uint8_to_hex ( get_temp_cmd[ cnt ], get_temp_hex_chr );
strcat ( get_temp_hex, get_temp_hex_chr );
}
if ( 0 == memcmp ( get_temp_hex, msg_ptr, strlen ( get_temp_hex ) ) )
{
ble10_clear_app_buf( );
log_printf( &logger, " - Get Temperature -\r\n" );
ble10_display_rsp ( RSP_OK );
}
}
}
ble10_clear_app_buf( );
}
Delay_ms ( 1 );
}

Note

We have used the nRF Connect smartphone application for the test. Make sure to configure the GATT Server properly in the nRF Connect application, then you will be able to send a desired command from it, once you connect to the Click board. You can use the Sample configuration for GATT Server which comes with the application installation and then send a command via Test Service from the Server.

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.BLE10

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.
