BLE Bluetooth module for IOT data transmission

As everyone knows, in the age of things, wireless connection has become a basic requirement. In this era, more and more objects will be connected to the Internet, and eventually achieve a connection to the host / cloud.

With the rapid development of wireless technology, the entire market has stood on the eve of the new era of the Internet of Things. No matter in life, work, or business scenarios, everything connected through the Internet of Things will provide user-centric intelligent services, which will also create a huge market.


At the core of the Internet of Things are millions of devices that will focus on transmitting data to the system. The information contained in these data may be various variables, such as temperature and humidity, the location of the user, the movement of the goods, and so on. The captured information is then transferred to the cloud or other devices (i.e., various "things") for data exchange or analysis. This also means that the market demand for high-performance, high-quality IoT wireless modules will also show a growing trend.

In the process of successfully connecting devices, the role of connectivity is crucial and the options are wide: such as Bluetooth Low Energy (BLE), Wi-Fi, RFID, NFC, and more. We will consider several factors in the selection of the solution, including environmental factors, sensor density, required connection distance, and transmission speed.


According to market share estimates, by 2021, 60% of wireless devices will use Bluetooth, and at the same time, 16% of devices will use Bluetooth Low Energy (BLE). Most of the growth will occur in applications such as smart homes, wearables, beacons, automotive electronics and medical electronics.
