# Title: BLE 9 Click Board™ ## Description: How Does The BLE 9 Click Board™ Work? The BLE 9 Click Board™ is based on the BGM220P, an RF performance Bluetooth Low Energy solution that provides BT/BLE connectivity for any embedded application from Silicon Labs. It supports Bluetooth 5.2, direction-finding, and Bluetooth Mesh Low Power Node protocols to deliver industry-leading accuracy. It comes with worldwide regulatory certifications and a fully upgradeable software stack as advanced development and debugging tool. The BGM220P module combines the EFR32BG22 wireless System on a Chip (SoC), required decoupling capacitors and inductors, 38.4 MHz and 32.768 kHz crystals, RF matching circuit, and an integrated ceramic onboard chip antenna. The EFR32BG22 SoC, inside the BGM220P module, includes an Arm Cortex-M33 processing core, up to 32Kb of RAM, up to 512kB of flash memory, and a 2.4GHz radio transceiver, offering up to 8dB output power. This Click board™ offers enhanced performance, security, and reliability to support IoT products running on Bluetooth networks. The BLE 9 Click Board™ communicates with MCU using the UART interface as its default communication protocol with the option for the users to use other interfaces such as SPI and I2C if they want to configure the module and write the library by themselves using these protocols. It also can be used in a stand-alone SoC configuration without an external host processor. In addition to these protocol pins, this Click board™ also has serial UART connections labeled as CTS and RTS, routed on the CS and INT pins of the mikroBUS™ socket, as well as Reset pin provided and routed at the RST pin of the mikroBUS™ socket. An additional GPIO pin, labeled as IO routed on the PWM pin of the mikroBUS™ socket, is left for configuration purposes as desired by the user. An onboard jumper selects the function of the CS mikroBUS™ pin between the SPI or UART communication pin. Selection is performed by positioning the SMD jumper to an appropriate position, labelled as CTS or CS. At the bottom of the BLE 9 Click is an additional header, the Mini Simplicity Debug Connector, which offers full support of debugging and programming capabilities. With this header, the user can use a serial wire debug interface for programming and debugging, using SWCLK and SWDIO pins, with Virtual UART COM port and Virtual UART-SWD-based interface also available through the SWD interface (SWDIO, SWCLK, and SWO). The BLE 9 Click Board™ is designed to be operated only with a 3.3V logic voltage level. A proper logic voltage level conversion should be performed before the Click board™ is used with MCUs with different logic levels. SPECIFICATIONS Type BT/BLE Applications Can be used for wireless networking in applications such as portable medical, connected home, asset tags and beacons, and more. On-board modules BGM220P, an RF performance Bluetooth Low Energy solution that provides BT/BLE connectivity for any embedded application from Silicon Labs. Key Features Bluetooth 5.2 Low-Energy (BLE) solution, firmware updates, enhanced security features, low power consumption, direction-finding, Bluetooth Mesh Low Power Node protocols to deliver industry-leading accuracy, and more.

We provide a library for the BLE 9 Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
The package can be downloaded/installed directly from NECTO Studio Package Manager (recommended), downloaded from our LibStock™ or found on Mikroe Github account.
This library contains API for the BLE 9 Click Board™ driver.
void ble9_cfg_setup ( ble9_cfg_t *cfg ); - function initializes click configuration structure to initial values.BLE9_RETVAL ble9_init ( ble9_t *ctx, ble9_cfg_t *cfg ); - function initializes all necessary peripherals.This example reads and processes data from the BLE 9 Click Board™.
The demo application is composed of two sections :
void application_task ( void )
{
ble9_process( );
}
The full application code, and ready to use projects can be installed directly form compilers IDE (recommneded) or found on LibStock page or mikroE GitHub accaunt.
Other mikroE Libraries used in the example:
Depending on the development board you are using, you may need a 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.
The BLE 9 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
