Why Bluetooth Modules?

Bluetooth modules are a wireless solution to mobile devise or machine-to-machine communication

, the simple answer is why Bluetooth Modules - because they are an easy alternative for wireless point-to-point communication across distances up to 60 feet and cost effective to boot. However, there are more reasons for Bluetooth modules being so popular.

Bluetooth modules will fit into any project or budget, Bluetooth modules are designed specifically to meet the cost, power consumption and small form factor requirements of mobile applications. If you need your new device to communicate with other devices wirelessly - why wouldn't you design it around a Bluetooth Module when Bluetooth Modules clearly tick all the usual design factor boxes?

Laird Technologies offers a diverse product line of Bluetooth modules that includes an embedded stack for instances where internal space is at a premium, and also Bluetooth modules that can be mounted directly to an external stack, where workable space is available. In addition to the expected RF and baseband functionality, some Bluetooth modules offer a dedicated microcontroller, antenna and connector integration, as well as on-board flash memory, voltage regulators, filters and crystals. Bluetooth has come on in leaps and bounds since it has been introduced a few years ago and there are many Bluetooth modules available on the market.

Low power Bluetooth modules provide robust, short-range data connectivity using embedded Bluetooth stacks, while supporting the latest Bluetooth Version 2.1 Specification with EDR (Enhanced Data Rate).

Bluetooth modules typically communicate with a host via a UART or Universal Serial Bus (USB) interface. In order to minimize power consumption, the Bluetooth module is activated only upon alert from a proximity sensor when the person is detected near the device.

Bluetooth modules of varying power class and brand can be interchanged at any time without any changes to the underlying hardware. This makes the change over to Bluetooth modules easy and at no extra cost.

They are short-range, compact and low-cost radio/baseband modules that can be implemented in any kind of electronic device. As the modules are generic products, they can be used for many types of applications that require a Bluetooth capability. The Bluetooth range of Bluetooth modules is around 328 feet standard (depending on the Bluetooth module used) but it may be increased to 3280 feet with different antennas.
