Product information "BLE 9 Click"

BLE 9 Click is a compact add-on board that provides BT/BLE connectivity for any embedded application. This board features the BGM220P, an RF performance Bluetooth Low Energy solution for IoT developers from Silicon Labs. Based on the EFR32BG22 SoC, the BGM220P enables Bluetooth Low-Energy (BLE) connectivity while delivering RF range and performance, firmware updates, enhanced security features, and low power consumption. It is optimized for wireless performance supporting Bluetooth 5.2, direction-finding, and Bluetooth Mesh Low Power Node protocols to deliver industry-leading accuracy. This Click board™ is suitable for wireless networking in applications such as portable medical, connected home, asset tags and beacons, and more.

BLE 9 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.

BLE 9 Click 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.

BLE 9 Click 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, labeled 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).

This 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.

Software Support:

We provide a library for the BLE 9 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 BLE 9 Click driver.

Key functions:

  • 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.

Examples description

This example reads and processes data from BLE 9 clicks.

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:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Ble9

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB 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.

MikroSDK:

This 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.

For more information about mikroSDK, visit the official page.
