The BLE 8 Click Board™ is a 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 Floating Point Unit (FPU) and state-of-the-art power performance. Reliable and easy to use, BLE 8 Click Board™ is a perfect solution for the development of various IoT applications, smart home applications, BLE enabled toys, advanced robotics, and other similar applications.
The BLE 8 Click Board™ provides Bluetooth Low Energy connectivity for any embedded application. It features the ANNA-B112, an integrated wireless connectivity solution. The ANNA-B112 module itself is based on the nRF52832 chip, a flexible, efficient Bluetooth 5 and Bluetooth mesh multiprotocol SoC. Armed with such a powerful processor, the ANNA-B112 can achieve data rates of up to 2 Mbps and up to 5 dBm maximum radiated output power using internal antenna, ensuring a reliable connection and good signal coverage. BLE 8 Click Board™ is ideal for small smart devices like home automation sensor and fitness applications that need to require really low-power consumption and long battery life.
How Does The BLE 8 Click Board™ Work?
The BLE 8 Click Board™ is equipped with the ANNA-B112, Stand-alone Bluetooth 5 low energy module by u-blox, which is based on the nRF52832 chip. The nRF52832 is the mid-range member of the nRF52 Series SoC family. It meets the challenges of a broad range of applications that need Bluetooth 5 feature sets, protocol concurrency and a rich and varied set of peripherals and features. In addition, it offers generous memory availability for both Flash and RAM. It is operated by a set of AT commands, over the UART interface, which makes the BLE 8 Click Board™ very easy to use.
By integrating most of the critical components on the chip, the ANNA-B112 allows the module to overcome any imperfections of external discrete components, allowing signal transmission power of up to 5dBm, and -92 dBm sensitivity for the receiver, using the on-chip antenna.
The ANNA-B112 module is built around an ARM® Cortex-M4 CPU with floating point unit running at 64 MHz. It has NFC-A Tag for use in simplified pairing and payment solutions, as well as numerous digital peripherals and interfaces such as PDM and I2S for digital microphones and audio. It is also fully multiprotocol capable with full protocol concurrency. It has protocol support for Bluetooth 5, Bluetooth mesh, ANT and 2.4 GHz proprietary stacks.
Besides the mikroBUS socket, the BLE 8 Click Board™ also features two optional 6-pin header mounts, with marked pin labels. All of these pins can be externally connected and used for various purposes. SWDCLK and SWDIO pins are reserved for the SWD interface, which the ANNA-B112 series modules uses for flashing and debugging. The rest of the external pins, labelled as IO1-IO10 are general purpose IO type and can be programmed according to the users needs.
The onboard buttons T1 and T2, as well as the RGB LED LD2 (labelled SYS), are also user programmable and can be used for various purposes for basic user interaction without any external components required besides the BLE 8 Click Board™.
The BLE 8 Click Board™ is designed to be operated only with 3.3V logic level. A proper logic voltage level conversion should be performed before the Click Board™ is used with MCUs with logic levels of 5V.

Software Support
We provide a library for the BLE 8 Click Board™ on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Library Description
This library allows user to perform a full control of the ANNA-B112 module. With this library user can send a commands to the module to perform the desired module configurations, connection with the other device, data transferring, and also can check the response from the module. User also can check the all necessary information about module. This library consists of the some predefined commands witch can be helpful to user to configure the module. For more details check full documentation.
Key Functions
void ble8_uartDriverInit( T_BLE8_P gpioObj, T_BLE8_P uartObj )- This function initializes UART driver.void ble8_response_handler_set( void ( *handler )( uint8_t* ) )- This function sets handler on the function which should be performed, for example function for the results logging.void ble8_uart_isr( void )- This function reads response bytes from the module and sets flag after each received byte.void ble8_send( uint8_t *tx_data, uint8_t term_char )- This function allows user to transmit data and send commands to the module.
Example Description
The application is composed of three sections :
- System Initialization - Initializes peripherals and pins.
- Application Initialization - Initializes UART serial interface, UART interrupt, and executes a module reset. Allows user to enter command mode.
- Application Task - (code snippet) - This function has two segments. First segment allows user to enter a commands, module configuration, data which will be transmitted, also to check all module and connection status by using the serial terminal. Press 'Enter' when you want to send the entered command (data). Press 'Backspace' to delete the wrong entered character before you send the command. Press 'Up-Down' or 'Left-Right' to see and enter a 3 last sent commands. Press 'Esc' and then 'r' or 'R' to execute a module reset. Press 'Esc' and then 't' or 'T' to enter command mode. Second segment allows user to check and get response from the ANNA-B112 module when response was ready.
