Wireless connectivity in electronic products that is, the ability of devices to communicate with one another without being physically connected - is a standard feature. Bluetooth low energy module are a good choice for applications that require a relatively short communication range with a focus on minimizing power consumption. Whether you’re designing a smart sensor, wearable, healthcare, home automation, industrial monitoring or IoT product, the versatility of Bluetooth Low Energy technology is a great solution for connected applications. Campus Components is your go-to for component solutions in wireless communication applications.
Bluetooth intended to allow communication between electronic devices in an energy-efficient fashion. This standard differs from wireless standards that are meant to provide a constant stream of high-volume data, BLE is great for use cases that communicate less data from time to time or triggered events. This standard is appropriate for battery-powered devices that need to operate over long periods of time. This standard supports readings from sensors, set up, status notifications, proximity, and communication with other smartphones, gateways, or networked devices.
A wireless module is obviously a good choice for many, but be sure to evaluate your technical requirements before making a selection, including: frequency, distance, host interface, maximum wireless speed, Bluetooth mode supported, power consumption, firmware features, security, antenna construction, and whether your wireless will operate within your application or be affected by your environment (metal walls, interference from other electronic equipment, the location of your antenna, etc.). Starting your evaluation process up front will pay off in a more reliable connected product.
A BLE module can make development easier as quite a few offer a production-worthy wireless platform in a small form factor. A module may include the radio hardware and antenna, a controller, firmware or firmware load, and a communication interface to a host microcontroller, depending on the specific product. Selecting a module may simplify RF design, but the developer will need to abide by the module vendor’s integration procedures as well as related regulations. This can be advantageous for those developing prototype or production connected devices.
For companies and engineering groups, sourcing is a key criterion for comparing suppliers of electronic parts. Technical compatibility, product datasheets, stock availability and ease of sourcing are factors to be considered. Campus Component offers a dedicated platform for electronic solutions that allows customers to compare the range of components used for embedded development, wireless, automation, learning, repair and manufacturing requirements. A sensible sourcing ensures developers can compare the different products to their intended application, not just by their names.
If you want to automate your house then BLE is a good option. Connected switches, temperature sensors, lighting and monitoring equipment all make use of short-range wireless communication to communicate with other hardware. The advantages of using a wireless communication standard also extend to wearable hardware, as small size and low power consumption are high priorities here. Fitness equipment and personal accessories can use wireless communication to send data, update records, and communicate with smartphone apps.
BLE can also be used in industrial applications. Wireless sensors can provide data on operating parameters, maintenance data or device status to an adjacent gateway or device. This may make a few of those tasks easier, cutting down on communication wiring. Still, industrial designers should consider environmental factors, interference, the necessary reliability of communication, security and the potential effects of lost connectivity before choosing BLE.
Beyond the hardware specification, developers will also need to think about security and software compatibility. The wireless module will need to work seamlessly with the host processor and the host software application. Depending on the type of data being transmitted, there may be requirements around pairing, encryption, authentication, firmware upgrades, access rights and permissions. Sticking to the documentation provided by the wireless module manufacturer and best practices around security will minimise any unnecessary vulnerabilities.
BLE modules are also a good starting point for students and enthusiasts wishing to get to grips with wireless and IoT development. A prototype could be used to harvest sensor data, send the data over a wireless connection to a smartphone, or enable a user to remotely configure a device. Working on something like this can give you a good grounding in everything from serial interfaces to embedded coding, to wireless protocols, to power and system management - the right kit and documentation makes it all much easier to get started.
Campus Component offers our customers the option to specify electronic components by product category and application. As you develop a wearable device, build a smart sensor, design a connected control system, or test a wireless prototype, it’s always important to choose the right hardware. Performing a quick compatibility check, understanding specs and thinking about future sourcing will save you time during the development process.
If you’re designing an electronics project that will require communication capabilities, Campus Component has the selection of wireless communication components you need to compare features and determine requirements to find the ideal solution for your application.
