What is Bluetooth 5.0 Module Ble Module？

PublishTime： 2022-01-20 Article Source：SKYLAB

Bluetooth 5.0 module ble module has now become the standard when it comes to wirelessly connecting mobile or portable devices directly. Thanks to Bluetooth, computers, smartphones and tablets, as well as peripheral devices such as keyboards and mice, communicate without cable clutter - and audio signals also reach speakers and headphones via Bluetooth.

There are definitely differences between different Bluetooth devices.

The development of radio technology was promoted by the Bluetooth Special Interest Group (Bluetooth SIG) in the late 1990s. Its founding members, including Ericsson, IBM, Intel, Nokia and Toshiba, wanted to establish a manufacturer-independent wireless standard.

The initiative achieved its goal within a few years, and today over 8,000 companies are members of the SIG. Moreover, this makes bluetooth 5.0 module ble module the most important wireless radio standard alongside WLAN. One of the greatest advantages of Bluetooth is the very stable connection between stationary and mobile devices.

Furthermore, the range a device has depends on the respective application scenario. With the new low-energy profile, ranges of up to 200 meters are theoretically possible.

What is the range for bluetooth 5.0 module ble module?

It is part of Bluetooth 5 and is especially relevant for the Internet of Things. For audio streams, the range is usually reduced to 10 meters due to the much larger data volume, but larger ranges would theoretically also be possible.

Furthermore, regardless of the type of use, obstacles such as walls have a strong influence on the range of the radio waves.

Bluetooth data rates increase significantly with each version

In terms of data rate, Bluetooth was modest in its early days. But it increased with each new generation: Bluetooth 2.0 already achieved a data rate of up to 2 Mbit / s and with Bluetooth 3 it increased again. The innovations of Bluetooth 4 and Bluetooth 5 were primarily aimed at wearable and data transfer in the IoT.

A particularly energy-saving operating mode for small amounts of data has been integrated. The fourth generation was expanded twice. Bluetooth 4.2 offers even more security than its predecessor. Such ordinal numbers will no longer exist in the course of blue tooth 5.

In the article on bluetooth 5.0 module ble module, we describe the innovations and their significance for the audio sector in detail.

The benefits of bluetooth 5.0 module ble module in streaming audio

Anyone who has ever connected their smartphone to headphones via Bluetooth can confirm that Bluetooth and audio streaming go well together. The range of Bluetooth audio devices has increased significantly again in recent years.

This has to do with the basic strengths of the standard on the one hand and with an important technological innovation on the other.

First of all, the general strengths

In addition to its connection stability and the comparatively high transmission speed, bluetooth 5.0 module ble module also impresses with its low power consumption. This is particularly advantageous for building mobile playback devices with rechargeable batteries.

In addition, little effort is important to establish a Bluetooth connection. In contrast to WLAN, no additional network device is important. It is sufficient if the devices have Bluetooth receivers and transmitters. Since there have also been better and better options for audio compression, the sound quality has also been correct.

Bluetooth profiles and audio compression

Different Bluetooth profiles are used depending on the area of application. For example, a printer needs a different profile than a cordless phone. A separate profile called A2DP is also specified for the transmission of audio data.

In principle, it would be possible to send audio files as MP3 or AAC via the bluetooth 5.0 module ble modules, but the files compress with an audio codec for fast transmission.

For which purpose SBC codec use?

The SBC codec use for this for a long time. Since this is a lossy compression process, this leads to a loss of quality, which was an important argument against Bluetooth transmission, especially for audiophile listeners. With aptX, however, another codec has become increasingly important in recent years, and this makes Bluetooth interesting for hi-fi enthusiasts as well.

Moreover, this codec comes on a different compression method that comes with significantly lower data loss. AptX is less of a new development and more of a rediscovery. The procedure appeared in the 1980s and 1990s. Moreover, it was common primarily in the area of ISDN telephony in order to ensure better voice quality.

What is not possible for blue tooth?

In order for aptX to really come into play, both the sender and the receiver must support the codec. If that's the case, nothing stands in the way of hi-fi quality with bluetooth 5.0 module ble module speakers.

What Bluetooth cannot and will not be able to do in the foreseeable future is the streaming of real surround sound formats for 5.1 configurations or more complex ones.

BT Link Bluetooth adapter

You simply connect this adapter to a free input via mini jack or stereo cinch cable. After pairing with any player, the audio signal is now output on the system.

Moreover, SKYLAB offer a large number of Bluetooth-enabled devices. These systems are easy to connect to a smartphone, netbook or tablet and then enable the best listening pleasure - without cabling.
