Bluetooth Modules

1.What is Bluetooth module?

• Bluetooth module is a chip's basic circuit set with an integrated Bluetooth function that is used for short-range 2.4G wireless communication.

2.What is Bluetooth module used for?

• Bluetooth technology manages the wireless part's communication channel. Bluetooth modules can wirelessly transmit and receive data using two devices. Using the host controller interface, the module can receive and transmit data from a host system (HCI).

3.Where can I buy beacons online?

• You can buy BLE modules online in India from authorized vendors or trusted sellers like Robocraze. Buying from authorized sellers proves the reliability and genuinity of the product and can be used for various IoT projects.

4.What are BLE beacons?

• BLE stands for Bluetooth Low Energy. BLE beacons are wireless communications that are designed for short range communications. Therefore, BLE beacons are devices used for short range communications. Beacon devices are small radio transmitters, strategically mounted throughout locations, to broadcast low energy Bluetooth signals in a given range. 

5.How is a BLE beacon different from a classic beacon?

• There are 2 major types of bluetooth technologies; Classic and BLE technology. The major difference between the two beacon technologies lies in the power consumption in each case. However there are other reasons why people choose BLE over the classic technology:
• BLE Beacons are suited for applications that work smoothly with a periodic transfer of data and cover very little battery usage at the same time. Hence, BLE is an ideal option for IoT and proximity marketing-related applications. 
• BLE can establish upto 20 connections at once. IT is able to support so many connections at once because it transfers small data packets and establishes quick connections. 

6.What are the beacon protocols?

• Eddystone:
  • Eddystone is a BLE (Bluetooth Low Energy) beacon released by Google in 2015.  It is an open format beacon created by Google and designed for complete transparency and freedom to develop creative projects. The eddystone format is built by working from leading industry experts in existing deployments and the wider beacon community. Eddystone includes a configuration service and branding materials.
• iBeacon:
  • Apple developed their own beacon protocol called the iBeacon. It is basically a BLE beacon that broadcasts its identifier to nearby portable electronic devices. The identifier and the several bytes sent, can be used in various real time applications like determining a device's physical location, tracking customers, push notifications and many more. 

7.What is a beacon-compatible app? Do I need an app to send beacon notifications?

• There are different types of beacon compatible apps and mainly depend upon the type of beacon protocol that you have decided to go with. Beacon apps enable you to manage your beacons remotely, integrate google or apple services with your beacon device and provide a better user experience by helping user’s device to discover content and functionality apps and the web.

8.What is the transmission range of beacons?

• The maximum range of beacons is around 70 meters. Additionally it can be adjusted to 7 different levels. The effective range of the beacon depends upon other external factors like specific locations and scale of it depending on the material and size of it.
