For decades, the Internet of Things (IoT) has been a buzzword. There are over 10 billion active IoT devices worldwide, and Bluetooth Low Energy is one of the key technologies enabling this market growth.

BLE( Bluetooth low energy) in IOT

– The Bluetooth Low Energy (BLE) is designed to run on very little power.

– Bluetooth Low Energy transmits data using 2.4 GHz radio frequencies.

– BluetoothLE has ultra low power consumption and it is small in size compared to classic bluetooth.

– It also has quicker connection capability and it transmits a small amount of data at low speed.

– BLE is leading IOT technology due to low cost and demand for it in the development community.

– It highly provides security compared to regular bluetooth devices.

– BLE is used in firmware to communicate with other devices that must support BLE.

– Bluetooth LE radio gives developers a significant amount of flexibility in designing products that meet the specific connectivity needs of their market.

– The Bluetooth SIG recognizes a number of low-energy technology markets, primarily in the smart home, health, proximity sensors, and fitness sectors.

BLE VS Bluetooth

When talking about BLE vs. Bluetooth, the major difference is low energy consumption capability. With low-energy consumption applications can run with a battery optimisation for a longer amount of time. Compared to Bluetooth the BLE provides a high range of data connectivity and has a big amount of radio frequency.

Attributes

GATT (Generic Attribute Profile)

The GATT profile is a generic specification for delivering and receiving small data packets known as “attributes” over a Bluetooth Low Energy channel. GATT is the foundation of all existing BLE application profiles.

GATT is based on the Attribute Protocol (ATT). ATT is designed to run on Bluetooth Low Energy devices. To that goal, it makes use of as few bytes as feasible. It is a standardised 128-bit string ID format used to uniquely identify data.

GATT server vs. GATT client

The Server is the device that exposes the data it controls or contains, as well as potentially other aspects of its behaviour that other devices can control.

A Client, on the other hand, is a device that communicates with the Server in order to read the exposed data and control the Server’s behaviour.

Bear in mind that a Bluetooth LE device can function as both a Server and a Client. Once they have established a connection, this controls how two devices communicate with one another.

Imagine you have a BLE-enabled activity tracker and an Android phone in order to better grasp the differences. In contrast to the activity tracker, which supports the peripheral role, the phone plays the central role. When the phone and the activity tracker connect, they begin transmitting GATT metadata to each other. Depending on the type of data being transferred, one or the other may serve as the server.

Common use case

Data transmitted in chunks(20 bytes at once) between devices:-

A communication channel needs to be established before any data can be sent between BLE-capable devices. After receiving authorization to use Bluetooth, your programme must access the BluetoothAdapter to check whether Bluetooth is turned on for the device.

Using proximity sensors to provide consumers with a personalised experience:-

We simplified it in three steps for easy comprehension:

Once Bluetooth is enabled, the device will search for nearby Bluetooth Low Energy (BLE) devices.
Connecting to the GATT server on the BLE device enables the discovery of a device’s capabilities when it is first found.
After a connection is made, depending on the features and services that are offered, data can be sent via the linked device.

Central vs. peripheral

This is the most standard method in BLE. A central device which is intended to be the BLE device that initiates outgoing connection requests to a peripheral device.

A Peripheral device that accepts incoming connection requests after advertising itself. This holds true for the actual BLE connection.

The peripheral device creates the advertisement, while the central device scans for potential advertisements. When compared to peripheral devices, central devices have more resources, such as computing power.

Services

A Service is a collection of Characteristics. A service represents a specific feature of a device, such as buttons or a specific sensor. A UUID identifies a Service. For example, you could offer a service called Heart rate monitor, which includes features like heart rate measurement. Each Service has the ability to define multiple Characteristics.Profile

A Profile is a collection of Services. Each Profile can have multiple Services defined. The Bluetooth SIG defines numerous profiles for Bluetooth Low Energy devices. A profile is a specification for how a device should behave in a specific application. It should be noted that a device can support multiple profiles. A device could, for example, include a heart rate monitor and a battery level detector.

Characteristics

Characteristics are made up of various parts. They have a type, a value, a set of properties, and a set of permissions. A UUID value indicating which type of Characteristic an Attribute is.

Characteristics are data items that relate to a specific state of the environment that the device can measure using a sensor. Internal state data includes the current battery level, which could be measured by a sensor. A characteristic, which stands for a piece of information or data that a server wants to make available to a client, is always a component of a service.

In a nutshell

BLE device requires low power and small data transmission. BLE optimises and reduces power consumption as much as possible and transmit data in chunks. When compared to other similar technologies, BLE modules and chipsets are less expensive and have a greater range. This is due to greater adoption and competition in the marketplace.

We have established our foothold in the IOT industry for more than 13 years, and we believe that by adding value, we can create products that are tremendously valuable.

As a business owner, you should always be searching for innovative strategies to grow your company in this ever changing digital world. In this case, Digital signage is the most effective way to boost business growth.

Emerging courtesy of next generation

Android Digital Signage refers to a smart screen that displays any type of content (informative, interactive, textual, or audio-visual) for business and mass communication purposes.

Digital signage is the most advanced type of advertising from a small display to big video walls. Admin can check the status of each device from their cloud-based Admin Console.

This signage is remotely controlled and used to display various contents. It saves money by decreasing the demand for printed materials and the personnel required. It is also primarily concerned with enhancing sales and client retention. Android Digital Signage is gaining ground into the world of digital advertising industry.

80% of firms that use digital signage report an increase in sales, with 33% of those sales coming from impulse purchases. Customers can view available products, their features and acquire further information without having to wait for a staff member. As a result, it is cutting perceived wait times by 40% on average and improving line management.

Leading Digital Signage to New Heights

By including interactive features that give users power over the experience, artificial intelligence elevates digital signage to new heights. With this technology, it is now feasible to obtain customised information about individual tastes, interests, and needs. Customers seek out products and services that are pertinent to them. They can see content that is more beneficial to them thanks to digital signage.

Yes, it is possible with the help of emerging technologies, business owners can detect which advertisement has received more views and from which floor. They can also determine the facial expression of each person who’s viewing the advertisement.

As we observe from our surroundings,

Malls and shopping centres are putting a lot of effort into developing fresh and enjoyable shopping experiences that are fuelled by digital signage for malls in order to draw in and keep new customers. Retailers are placing digital signs in high traffic areas like the food court and entrances to generate additional marketing and promotion opportunities.

Without further ado, let’s review its aspects.

Modes of Android Digital Signage

POS (Point of Sale):

Android, Windows, and Linux are supported by POS Systems. It is crucial to take into account the extensive use of technologies at every touchpoint because selecting a POS system influences technological selections made throughout the store. POS touchscreen computers that are all-in-one and potent tiny PCs that offer performance, flexibility, and style. Make a stack that works for your company.

Point-of-sale (POS) terminals are present everywhere, emerging from the typical cash wrap in the form of self-checkout kiosks, mobile device scanning at the curb, and even pay-with-your-face technologies. These devices run the Android operating system.

Kiosk Mode:

Self-service kiosks let customers take charge of their experiences by enabling self-ordering, self-checkout, and guest check-in. Self-ordering kiosks quickly identify consumer demand, enabling quicker fulfilment and greater client satisfaction. It contributes to quick response times, precise ordering, liberating experiences, and higher revenues.

In general, Android-powered kiosks are less expensive than conventional kiosks, and businesses can cut costs while bridging the gap for customers by converting an existing mobile app for kiosk use.

FEATURES of Android Digital Signage

High-definition image galleries

Because today’s shoppers are busy, you must grab their attention by displaying exciting images on your digital screen. Photos are visually appealing and one of the quickest ways to reach out to modern consumers. You can share your own images, as well as those of your advertisers and sponsors, as well as images shared by your customers.

VIDEO

videos like (AVI, MPEG, MP4, MOV, WMV, MKV) displays with the audio format capture more attention instantly than pure text alone.

Essential notices

Use digital signage for malls to share important on-demand information with mall visitors. The digital signage can be used to announce the opening of a new store, parking hours, and mall events.

Website

Share your website or any other URL in one section of the screen. You can display your website, blog pages, or any other interesting site. This is especially useful if you have an impressive landing page, an ongoing online campaign, or a new product that is about to be released.

Assessment

With Performance Monitoring, you can quickly identify performance issues and view the full end-to-end distributed trace to see the exact poor-performing API call and what caused it. Measure everything from warm starts to frozen frames to improve Android performance with maximum efficiency rather than maximum effort.

Display the weather, and RSS news.

Slideshow’s web interface allows you to add different panels to the screen in addition to displaying files, current date and time, weather information for the next few days, and RSS news for your favourite provider.

Remotely Overhaul Anytime & Anywhere

You can manage the system remotely, and any changes you make are automatically synchronised across all displays. This remote management facility enables quick troubleshooting and saves the high costs associated with delays and incorrect digital signage.

OTA update

In a manual Over-The-Air software update, either the device is initially configured to check for updates on a regular basis, or the user must explicitly click on a link to check for updates. To upgrade several devices anytime anywhere we use automatic OTA. Automatic Over-The-Air software updates are best suited to devices that are not operated by a human. The update is managed by an MDM hub.

Detection of bugs

Improve workflow by having a complete view of releases, allowing you to mark errors as resolved and prioritise live issues. Even when devices are offline or in aeroplane mode, record Android stack traces and send errors as soon as the connection is restored. which version a bug first appeared in, merge duplicates, and determine whether things will regress in a future release. Add commit data to automatically suggest an owner for each application error and send deploy emails immediately.

Benefits of Android Digital Signage

Easy to use across multiple devices

Simply install our Digital Signage software on your Android smartphone, tablet, TV, stick, or box, launch it, and through, router admin can control and custom files anytime anywhere.

Next-generation Digital Signage

The primary purpose of Digital Signage is to disseminate information. Nowadays, it has emerged to the point where you can collect data with the help of AI. Retailers can analyse which advertisement has received the most attention from customers by using next-generation digital signage solutions that include features like facial recognition.

The term “artificial intelligence” refers to much more than just a face recognition system. Since digital signage AI uses consumer data to choose which advertisements to show to each individual, based on their interests. Since digital signage AI uses consumer data to choose which advertisements to show to each individual, based on their interests. This information can help digital signage to display specific advertisements.

Some products may be preferable to others on a rainy day or in colder weather. Ads could be displayed based on not only analytics but also based on weather report. Furthermore, digital signage content can also be automatically adjusted, shopping decisions are likely to be influenced by weather information.
