WSKIT4BLTE-AT

Wireless Short-Range Device (WSRD) devices or short range devices (SRDs) are becoming increasinglyimportant components in the growing enterprise wireless ecosystems. They are used for severalapplications such as automation, industrial process control, healthcare, asset management, andsurveillance. This article examines the WSKIT4BLTE-AT application field and working principle.

WSKIT4BLTE-AT is a short range radio frequency transceiver device designed to provide interoperable wireless sensing solutions based on Bluetooth Low Energy (BLE). WSKIT4BLTE-AT is developed by WNetwork Technology, a professional RF Wireless Solution supplier. It offers both a transceiver and a protocol stack to simplify development and reduce time needed to achieve BLE solutions. The WSKIT4BLTE-AT is based on the ATmega2560 microcontroller, and is developed as per the 4.1.2+ EDR BLE protocol.

The WSKIT4BLTE-AT is designed to deliver an easy-to-use, reliable short-range wireless solution for applications that require low-power, low-latency data transmission. It consists of an RF transmitter-receiver pair that operates in the 2.4 GHz range. The device is suitable for numerous applications such as home automation, industrial monitoring, healthcare applications, asset monitoring, and surveillance. WSKIT4BLTE-AT is compatible with multiple RF modules and radio technologies such as BLE, Z-wave, and ZigBee. It is capable of reaching radio transmit power of up to 22 dBm and provides an extended signal range of up to 1200m in open areas. The device also supports various modes of operation such as broadcast, shared, and point-to-multipoint.

WSKIT4BLTE-AT also offers a comprehensive open source software development kit that simplifies the development of BLE-enabled applications and eases integration. This includes a series of C and Python libraries that allow developers to connect modules to a personal computer and exchange data over the air, and provide BLE services and characteristics. Additionally, the WSKIT4BLTE-AT provides a user-friendly graphical programming environment that enables users to quickly create and modify complex BLE applications with no prior programming experience.

In addition to being an ideal RF Evaluation and Development Kit, WSKIT4BLTE-AT can also be used as a baseboard for reference designs and as a Booster Pack to create an RF Platform. The device can easily be incorporated into an existing solution, and it provides a simple, low-cost way to reduce development time and cost.

The working principle of WSKIT4BLTE-AT is quite simple. The device operates in a master-slave architecture in which the user is the master and the BLE devices are the slaves. All communication and data transactions between the master and the slave take place via radio transmission. The master device sends data requests to the slave in a specific format known as BLE advertisement, which includes a header, data, and footer. When the slave receives the request, it responds with the required data. The communication between the master and slave is encrypted using BLE protocol, which ensures secure data transmission and data integrity.

In conclusion, WSKIT4BLTE-AT is a highly capable, yet easy-to-use short-range wireless device that provides an excellent platform for development and integration of wireless data transfer solutions for applications such as home automation, industrial monitoring, healthcare, asset monitoring, and surveillance. The device is designed to be simple and straightforward, offering a comprehensive set of tools needed to develop and maintain BLE applications with a high degree of accuracy and assurance. With the reliability and scalability provided by the WSKIT4BLTE-AT, developers can now create RF Evaluation and Development Kits and boards with greater efficiency and cost savings.
