The Wireless SUN Click Board™ is a compact add-on board representing a Wireless Smart Utility Network for Field Area Network (Wi-SUN FAN) solution. This board features the BP35C5, a Wi-SUN FAN-compatible wireless communication module from Rohm Semiconductor. The BP35C5 operates in the 920MHz band and includes a Wi-SUN software stack that enables operation at different transmission modes for high efficiency. Besides, certification under ARIB and the FCC allows immediate use in Japan and the US in large-scale (up to 1,000-node Sub-GHz) multi-hop mesh networks supporting channel hopping. This Click board™ is suitable for social infrastructures such as traffic lights and street lights, smart buildings, and logistics, allowing a remote management system to be built that covers the entire city.
The Wireless SUN Click Board™ is supported by a mikroSDK-compliant library, which includes functions that simplify software development. This Click board™ comes as a thoroughly tested product, ready to be used on a system equipped with the mikroBUS™ socket.
How Does The Wireless SUN Click Board™ Work?
The Wireless SUN Click Board™ is based on the BP35C5, an ultra-compact Wi-SUN FAN compatible wireless communication module from Rohm Semiconductor. The BP35C5 has been certified by the Radio Law of ARIB and FCC, so it can be used in Japan and the United States operating at the frequency of 920MHz with a binary GFSK modulation method. It also includes a Wi-SUN software stack that enables operation at different transmission modes (20, 10, or 1mW) for high efficiency. In addition, since it has a built-in security function and supports communication encryption and security key update on the module side, it can perform secure communication efficiently without complicated control.
As mentioned before, this module uses the Wi-SUN FAN (Field Area Network) mesh networking protocol, consisting of a parent repeater called Border Router, a repeater called Router, and a terminal called Leaf. It can cover a wide range because of its relay function (hopping function). That's why it is possible to build a mesh network of up to 1000 units - multi-hop mesh networks supporting channel hopping with the ability to avoid radio interference by automatic routing (ability to switch routes automatically). This feature makes it suitable for social infrastructure applications such as traffic lights and street lights, building a remote management system that covers the entire city.
The Wireless SUN Click Board™ communicates with MCU using the UART interface with commonly used UART RX, TX, and hardware flow control pins UART CTS and RTS (Clear to Send and Ready to Send). It operates at 115200 bps by default configuration to transmit and exchange data with the host MCU. Besides, additional onboard test points TP1 and TP2 offer users full support of debugging and programming capabilities through a Serial Wire Debug interface for programming and debugging, available through the SWD interface pins (SWCK and SWD).
In addition to the appropriate interfaces, this Click board™ also has some additional features. A Reset button routed to the RST pin on the mikroBUS™ socket puts the module into a Reset state. At the same time, a blue LED indicator labelled STATUS represents a broadcast transmitting status LED indicator.
The Wireless SUN 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. 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.

Additional Notes and Information
Depending on the development board you are using, you may needs a USB UART Click Board™, 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. UART terminal is available in all MikroElektronika compilers.
MIKROSDK
The Wireless SUN 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.
