What is ble bluetooth wireless module?

We are all very familiar with Bluetooth technology as it widely used in daily life. And you will occasionally hear the word Bluetooth Low Energy (BLE). Bluetooth technology has become so familiar to users of technology devices from phones, headphones, smart speakers, etc. So what is a Bluetooth wireless module? What is the difference with Bluetooth? Let SKYLAB（天工测控）tell you about this!

1. What is Bluetooth Low Energy (BLE)?

Bluetooth Low Energy (BLE / Bluetooth LE / Bluetooth Smart) – Translation: Bluetooth Low Energy – low energy wireless networking technology used to connect devices together.

A technology that was originally designed by Nokia in 2006, before being announced and implemented by the Bluetooth SIG in parallel with the release of Bluetooth 4.0 in 2010 called Bluetooth. Low Energy (abbreviated as BLE or also known as Bluetooth Smart).

BLE is a wireless connection and communication technology using the 2.4GHz band with the outstanding feature of consuming very little power while maintaining a stable connection in a wider range than Bluetooth.

BLE Bluetooth wireless module is not seen as an evolution of the Bluetooth standard, new technology into IoT – devices with low data transfer rates.

2. Bluetooth and Bluetooth Low Power: What's the Difference?

Bluetooth and BLE are not the same in terms of working mechanisms and how they are applied. In practice, this technology is used for very different purposes:

Bluetooth is generally suitable for processing, transmitting, and discussing large amounts of data (e.g. audio, video). However, it will be more energy-efficient and more expensive.

Ble Bluetooth wireless module is suitable for the software that does not require large data transmission, so it can receive a small amount of data. And as a result, the device can run out of battery in 5 days at a lower cost than Bluetooth because it does not require a continuous connection.

As a result, BLE technology, on the other hand, is suitable for applications. That does not require the transfer of large amounts of data and thus can only recover some information (such as time or temperature).

3. What are the uses of BLE?

Bluetooth Low Energy is available in the market with the expectation that it will bring full effect to the buyers through IoT devices, as it is commonly used in smart devices with a wide range of software. As:

The setup counter tracks the locations of characters with great accuracy – Samsung SmartTag. This is a device that attaches to different objects so that the owner can simply find it when it is needed.

Let's go with us to discover the answer to the question of what BLE is and how it is different from normal BLE Bluetooth wireless module technology right in the article below.

● Samsung Smart Tag

1 smart home with smart mobile phone control, for example, August Smart Lock will turn a buyer's smartphone into an electronic key.

● August smart lock

Smart Intelligence provides tracking and marking information on user usage and smartphone data synchronization.

● Healthcare

In the field of healthcare, BLE technology is incorporated into the CGMP device by software, helping to monitor glucose levels.

● Dex com G5 Mobile CGM

Beacon, one of the latest developments in local technology and PR, can identify and send product/PR information to customers at the store location through smartphones.

● Bluetooth Measure signal

BLE Bluetooth wireless module's central technology software is usually a smartphone, laptop, or notebook computer with iOS, Android, Windows Phone and macOS, Linux, Windows 8, and Windows 10 software.

4. BLE device models

There are 2 types of BLE devices, Bluetooth Smart and Bluetooth Smart Ready.

● Smart Bluetooth (Single-Mode)

It can only connect to Bluetooth Smart or Bluetooth Smart Ready devices.

● Bluetooth Smart Ready (Dual Mode)

Devices connected to a central location such as laptops, smartphones, and laptops use BLE Bluetooth wireless module Smart Ready chips (Dual Mode).

5. The pros and cons of BLE.

Every technological device is not always excellent in its own way, it will always have its pros and cons, and for us, that is no different, low Bluetooth power.

● BLE Bluetooth wireless module Benefits

Firstly, the ability to use minimal power, allowing the device to run for several months or a few years with a coin battery easily just because the machine opens when data is in / out and closes when not, Consecutive data.

The data models and chips used to design Bluetooth LE are cheap and sophisticated, so the technology is also quite cheap.

BLE Bluetooth wireless module VNG nRF51822 works with the 2.4GHz ISM band, which avoids interference between WiFi and Bluetooth devices.

The process of establishing a connection and transferring data is very fast (approximately 3ms). Most importantly, integrating BLE technology into many smartphones on the market today offers many advantages over other smartphones.

● Small data transmission with BLE Bluetooth wireless module

The frequency of BLE Bluetooth wireless module wavelength in space is 1Mbps. This is the upper limit of the theoretical throughput. However, in practice, this parameter is small due to the impact of many factors.

Conclusion BLE Bluetooth wireless module

The device can run on battery power for several years at a lower cost than Bluetooth, as it does not require a constant connection. This makes BLE Bluetooth wireless module suitable for IoT (Internet of Things).

BLE can establish up to 20 connections at a time. It supports more concurrent connections as it transmits small data packets and establishes fast connections. Bluetooth can only establish 7 simultaneous connections.
