Library Description

The library covers all the necessary functions to control BLE 6 click board. Library performs a standard UART interface communication.

Key functions:

• uint8_t ble6_read_byte( void ) - Read Single Byte.
• void ble6_write_byte ( uint8_t input ) - Write Single Byte.
• void ble6_send_command ( uint8_t *tx_data, uint8_t n_bytes ) - Send command function.

Examples description

The application is composed of three sections :

• System Initialization - Initializes UART, sets RST, CS and PWM pin as outputs and begins to write a log.
• Application Initialization - Initialization driver enables - UART, sets handlers initialize and enable UART interrupt, reset and configures BLE module, initialize BLE Server Profile ( Services and Characteristics ).
• Application Task - (code snippet) This example demonstrates the use of the BLE 6 Click board. The app starts by checking the system ready flag and returns the Bluetooth device address. After that, the chain of commands creates Primary Server Profiles: Device Information, Generic Access and Custom Service to Start Advertising. For transmit messages, we use Generic Access Primary Service with Write permissions of the characteristic Element. In this example, transmitting message is limited to a maximum of 11 characters. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( )
{
     ble6_event_handler( );
     
     while ( device_connected_flag )
     {
        if ( ble6_strncmp( &rx_response[ 0 ],&hci_le_serverwrite_event[ 0 ], 1 )
             == 0 )
        {
            ble6_response_handler( );
        }
     }
}

Additional Functions :

• void ble6_handler ( ) - Default handler.
• void ble6_connect_handler ( ) - Connect handler.
• void ble6_response_handler ( ) - Response handler.
• void ble6_event_handler ( ) - Event handler.
• void ble6_local_version_info ( ) - Display local version information.
• void ble6_fw_details ( ) - Display FW details.
• void ble6_le_meta_event ( ) - Meta event.
• void ble6_aci_gap_init ( ) - Display ACI GAP init. information.
• void ble6_display_log ( ) - Display log.
• ble6_module_init ( ) - Module initialization.

Other mikroE Libraries used in the example:

• UART
• Conversions

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.
