Bluetooth Components and Modules

Envistia Mall stocks a variety of Bluetooth modules designed for OEM and other applications requiring compact, high-performance Bluetooth communications solutions. These components and modules are available in Surface Mount (SMD) packages for high-volume OEM applications, or for applications requiring automated assembly, low cost or small size. They are also offered in Dual In-Line Pin (DIP) packages with chip antennas ("D" packages), or with connectors for external antennas. 

CHIPSEN Bluetooth Modules

CHIPSEN Bluetooth modules, available in both Bluetooth Low Energy (BLE) and Bluetooth Classic*, are designed for OEM and other applications requiring compact, high-performance Bluetooth communications solutions. The modules are available in Surface Mount (SMD) packages with integrated chip antennas for high-volume OEM applications, or for applications requiring automated assembly, low cost or small size. They are also offered in Dual In-Line Pin (DIP) packages with chip antennas ("D" packages), or with connectors for external U.FL ("DU" packages) and SMA antennas ("DS" packages).     

RF Certification Fee Exemption

If you create a wireless product using an uncertified module, you must obtain your own wireless certification. CHIPSEN Bluetooth modules already have multiple certifications (typically SIG, KC (including wireless EMC), FCC, CE and TELEC), reducing the cost and certification process of manufacturing your wireless products.

What is the Difference Between Bluetooth Classic and Bluetooth Low Energy (BLE)

Bluetooth Low Energy (BLE), introduced in Bluetooth 4.0, is optimized for ultra-low power consumption in battery-powered devices requiring infrequent data transfers, while Classic Bluetooth (BR/EDR) supports higher data rates for continuous streaming like audio.

Key Differences Between Classic Bluetooth and Bluetooth LE

Aspect Classic Bluetooth Bluetooth Low Energy (BLE)
Power Consumption
Higher; always on or off, drains battery quickly for streaming.
Much lower; sleeps until needed, lasts months/years on coin cells.
Data Rate
Up to 2-3 Mbps (ideal for audio/video).
Up to 1-2 Mbps (small packets only).
Latency
Higher (slower response to input).
Lower (faster response).
Use Cases
Streaming audio (headsets, speakers), file transfers, phone calls.
Sensors, fitness trackers, IoT, medical devices (periodic data).
Range
Typically longer (up to 100m+).
Short-range (~100m), extendable.
Connection
Continuous, requires pairing.
Intermittent, often no pairing needed.
Compatibility
BR/EDR modes; not interoperable with BLE.
Separate protocol; devices must match.

BLE complements rather than replaces Classic Bluetooth, prioritizing energy efficiency over speed. Both operate in the 2.4 GHz band.

It’s important to note that each mode has different physical layer modulation and demodulation methods. This means that Bluetooth LE and Classic Bluetooth devices cannot communicate with each other. If the master device is a Bluetooth LE device, the slave device must also be a Bluetooth LE device.

Modern Smartphones can work with both

There are a dual-mode Bluetooth devices which support both Bluetooth LE and Classic Bluetooth. Cell phones are the most common example. Most modern smartphones can communicate with both Classic and BLE devices.

To achieve this, smartphones use a time-sharing mechanism to communicate using both Bluetooth modes. Smartphones allow dual-mode Bluetooth chips to continuously switch between modes to support both Bluetooth LE devices and Classic Bluetooth devices.
