Why BLE SOC is needed for IoT?

Low Power Consumption

BLE SOCs are perfect for battery-powered devices since they are made with minimal power consumption in mind. They include energy-saving functions including sleep modes, effective data transmission protocols, and improved radio frequency performance. This enables gadgets to have longer battery lives, which makes them appropriate for wearable technology, IoT technology, and other portable applications.

Wireless Connectivity

BLE SOCs allow for Bluetooth-enabled devices to connect wirelessly and interact with one another as well as with other Bluetooth-enabled devices, such as computers, tablets, and smartphones. The contact with external devices, control of the gadget, and seamless data transfer are all made possible by this connectivity. BLE is perfect for Bluetooth IoT devices and sensors since it is particularly well-suited for applications requiring intermittent data exchange or low bandwidth.


The Bluetooth Low Energy standard compliance of BLE SOCs ensures compatibility and interoperability with a variety of Bluetooth-enabled devices. Due to this standardisation, devices using BLE SOCs may smoothly connect and interact with one another independent of the maker or platform.

Integration and Miniaturization

By integrating several parts and functions onto a single chip, BLE SOCs help devices become smaller and simpler. Through this integration, the design and production processes are made simpler, the cost is reduced, and smaller, lighter devices are now possible. It is especially useful for wearable technology such as remote patient monitoring wearables, where form factor and size are important factors.

Program Development

BLE SOCs usually provide software development kits (SDKs) and support for a variety of programming languages, which makes it easier to design applications. Designing cutting-edge features like data synchronization, wireless updates, and proximity-based interactions is made simpler by these SDKs’ tools, frameworks, and APIs.

A multitude of hardware development resources, including SDK and burning tools, are provided by Dusun IoT to aid the developer in finding the ideal solution for his particular requirements.

How is a BLE SOC measured?

Taking into account numerous performance metrics, a data-based and thorough methodology is needed to evaluate the quality of a BLE SOC. Here are some important aspects to take into account while assessing a BLE SOC’s level of quality:

Consumption of energy

A BLE SOC’s power consumption is an important consideration, particularly for battery-powered devices. It is crucial to gauge the SOC’s power utilization in a variety of conditions, including active communication, idle mode, and sleep mode. Data like current consumption in various operational modes and the effects of various transmission power levels may be used to evaluate the SOC’s power efficiency.

Distance and Signal Power

The BLE SOC’s capacity to create and sustain connections with other devices depends on its range and signal strength. The performance of the SOC may be determined by analyzing the connection quality, signal-to-noise ratio (SNR), and received signal strength indicator (RSSI) at different locations and at varying distances. Its resilience and dependability may be evaluated by testing under various conditions, such as line-of-sight, blocked surroundings, or interference-prone places.

Throughput of data

The speed of data transmission between devices depends on the data throughput of a BLE SOC. The effectiveness of the SOC in processing data may be determined by measuring the attainable data transmission rate under various conditions, such as varied distances and degrees of interference. To make sure that data transmission is smooth and dependable, factors including packet loss, latency, and data rate variations should be considered.
