RYB080I Click

How does it work?

RYB080I Click is based on the RYB080I, a 2.4GHz Bluetooth 4.2/5.0 Low Energy (LE) module from REYAX. Featuring an integrated antenna, this module is designed for seamless connectivity with smartphones and various Bluetooth-enabled devices. This module is based on the TI CC2640R2F ARM® Cortex®-M3 microcontroller, an industry-standard chip known for its efficient performance and reliability, and supports a dual-connection feature, enabling it to maintain simultaneous communication with two Bluetooth devices. It also supports both Host and Client roles, making it highly adaptable for various wireless communication scenarios. With its robust functionality, this Click board™ is ideal for remote monitoring and control applications, smart home systems, and indoor positioning solutions.

One of the module’s key advantages is the integrated metal cover, which protects against electromagnetic interference (EMI), ensuring stable and reliable operation even in environments with significant signal noise. It operates on the widely adopted Generic Attribute Profile (GATT), enabling smooth interaction with Bluetooth Low Energy devices. Control and configuration are easily managed using REYAX-developed AT commands, simplifying setup and integration into various projects. Certified under FCC CFR47 Part 15 (US), NCC (Taiwan), and MIC (Japan), the RYB080I meets rigorous international standards, offering compliance and reliability for global applications.

This Click board™ is designed in a unique format supporting the newly introduced MIKROE feature called “Click Snap.” Unlike the standardized version of Click boards, this feature allows the main module area to become movable by breaking the PCB, opening up many new possibilities for implementation. Thanks to the Snap feature, the RYB080I can operate autonomously by accessing its signals directly on the pins marked 1-8. Additionally, the Snap part includes a specified and fixed screw hole position, enabling users to secure the Snap board in their desired location.

Regarding the board’s connectivity features, this Click board™ uses a UART interface for communication with the host MCU, using standard UART RX and TX pins to exchange AT commands. By default, it communicates at a baud rate of 115200bps. Additionally, unpopulated JTAG header pins provide full support for debugging and programming. This header allows users to use a Joint Test Action Group (JTAG) industry standard for programming and debugging via these JTAG pins. Along with the communication and control pins, this Click board™ also includes a reset pin (RST) and a RESET button, enabling easy module resetting and a six test point that connects to the module general-purpose I/O pins, allowing further customization.

This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. It also comes equipped with a library containing functions and example code that can be used as a reference for further development.

Click Snap

Click Snap is an innovative feature of our standardized Click add-on boards, introducing a new level of flexibility and ease of use. This feature allows for easy detachment of the main sensor area by simply snapping the PCB along designated lines, enabling various implementation possibilities.

Software Support

We provide a library for the RYB080I Click as well as a demo application (example), developed using MIKROE compilers. The demo can run on all the main MIKROE development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager (recommended), downloaded from our LibStock™ or found on MIKROE github account.

Library Description

This library contains API for RYB080I Click driver.

Key functions

• ryb080i_cmd_run This function sends a specified command to the click module.

• ryb080i_cmd_set This function sets a value to a specified command of the click module.

• ryb080i_cmd_get This function is used to get the value of a given command from the click module.

Example Description

This example demonstrates the use of RYB080I Click by processing data from a connected BT device.

void application_task ( void ) 
 { 
     switch ( app_state ) 
     { 
         case RYB080I_POWER_UP: 
         { 
             if ( RYB080I_OK == ryb080i_power_up( &ryb080i ) ) 
             { 
                 app_state = RYB080I_CONFIG_EXAMPLE; 
                 log_printf( &logger, ">>> APP STATE - CONFIG EXAMPLE <<<rnn" ); 
             } 
             break; 
         } 
         case RYB080I_CONFIG_EXAMPLE: 
         { 
             if ( RYB080I_OK == ryb080i_config_example( &ryb080i ) ) 
             { 
                 app_state = RYB080I_EXAMPLE; 
                 log_printf( &logger, ">>> APP STATE - EXAMPLE <<<rnn" ); 
             } 
             break; 
         } 
         case RYB080I_EXAMPLE: 
         { 
             ryb080i_example( &ryb080i ); 
             break; 
         } 
         default: 
         { 
             log_error( &logger, " APP STATE." ); 
             break; 
         } 
     }
