The BLE Tiny Click Board™ as its foundation uses the DA14531MOD, SmartBond TINY™ module based on the world's smallest and lowest power Bluetooth 5.1 System-on-Chip (SoC) from Dialog Semiconductor. The DA14531 is based on the powerful 32-bit Arm Cortex-M0+ with integrated memories and analogue and digital peripherals. It comes with next-generation Codeless software that allows the design of Bluetooth applications without Bluetooth knowledge or advanced programming skills, using a comprehensive set of AT commands.
This module is supported with software to lower the threshold of using BLE technology. The DA14531 comes with configurable DSPS (serial port service) and next-generation Codeless software to design Bluetooth applications without Bluetooth knowledge or advanced programming skills. It is specifically optimized to significantly reduce the cost of adding Bluetooth low energy functionality to an IoT system. The SmartBond TINY module is certified for worldwide operation, with Federal Communications Commission (FCC) certification for the Americas and CE certification for Europe.
The BLE Tiny Click Board™ communicates with MCU using the Single-Wire UART interface as its default communication protocol for exchanging AT commands with the host and data transfer. A switch labelled as 1WIRE EN is used to activate this communication, which allows the module to establish communication via the Single-Wire UART Receive and Transmit pin, or only via the standard UART TX pin.
For that purpose, this Click board™ uses the 74LVC1G3157 multiplexer to avoid conflict with other functions driven by the same GPIOs. In this way, the user is given the option of using the P0_6 pin, which carries a dual function, a UART TX pin, or a pin to be used for the ADC's analogue pin. The function of this pin is selected by populating the appropriate jumper labelled as P0_6 SEL.
The DA14531 comes in with a predefined default configuration. However, due to the low GPIO pin count, several functions are multiplexed and can be enabled as needed through onboard jumpers. The users can also use other interfaces such as SPI or I2C to configure the module and write the library by themselves by populating the appropriate jumpers (P0_11 and P0_9 SEL).
The BLE Tiny Click Board™ also provides a JTAG interface with SWDIO data and SWCLK clock signals available on header J1. This way, the user has the opportunity to program a particular version of the CodeLess software via the JTAG interface, which is required by the DA14531 module itself. Also, this Click board™ can be reset through the Hardware Reset pin, labeled as RST on the mikroBUS™ socket, by setting this pin to a high logic state.
The BLE Tiny Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
The integrated next-generation Codeless firmware v2.0 is programmed in the built-in Flash of the DA14531 module and allows you to quickly get started with wireless IoT applications without developing a single line of code. It uses the well-known concept of AT Commands that can be used to perform various tasks; in particular, control of BLE connectivity (connect/disconnect, scan for nearby devices, report BLE address...), interaction with the environment/sensor readout (set GPIOs, read external interfaces, report GPIO status...), and more. For the complete information on available AT commands supported with firmware, please refer to the CodeLess User Manual, which covers all the information related to CodeLess.
