The top long-range Bluetooth modules of 2023

By Nikhil Agnihotri September 5, 2023

Bluetooth, which offers short-range wireless technology, is now standard on most smart devices, including wireless headphones, smart watches, remote controls, game controllers, and many more. Most of these devices are designed to operate with smartphones or computers. 

Audio streaming, file sharing, peripheral devices, the Internet of Things (IoT), and smart home devices are some common Bluetooth applications. 

Bluetooth allows devices to communicate wirelessly over short distances. The wireless interface is known for its low power consumption, wide range of coverage, encrypted data transfer, high compatibility, and ease of use.

The latest version of Bluetooth is Bluetooth 5.3, released in July 2021. While the maximum range of Bluetooth 4.x was 60 meters in ideal conditions, Bluetooth 5.x provides a maximum range of 1350 meters. The indoor range of Bluetooth 4.x was limited to 10 meters with the use of an antenna, and that has increased to 30 meters with Bluetooth 5.x. 

Although Bluetooth was developed for short-range communication, that’s changed with the latest version. Now, Bluetooth can facilitate electronic applications with a descent range indoors and outdoors, which has opened new potential for the technology. It also supports faster data rates of up to 2 Mbps, allowing for simultaneous connections of up to eight devices. 

A few notable features of Bluetooth 5.3 include: 

  • Periodic Advertising Enhancement – improves Bluetooth advertising, which is how devices find one another
  • Channel Selection – lets devices select the best channel for communication, which has improved the range and reliability of the connection
  • Message Authentication Code (MAC) 3 – significantly increases security to ensure conversations are private

Bluetooth has become an integral part of several mainstream microcontroller boards and microcomputers. While microcontroller boards and microcomputers are excellent for prototyping, production models are often built on standalone microcontroller chips, where peripherals are explicitly integrated onboard. The same is true with the addition of Bluetooth. Most production devices rely on a specific chip or board to add Bluetooth. 

Although Bluetooth has become standard, the Bluetooth chips and modules from different vendors differ. Some applications demand high-speed data communication over range capacities and vice versa. So, the latest Bluetooth modules accommodate these requirements. 

In this article, we’ll cover the top Bluetooth modules that offer the most extended range. We’ll also review some of the more popular Bluetooth 5.3 modules. 

Long-range modules
The top Bluetooth modules with the longest range include: 

1. Fanstel BT832XE
2. Semtech SX1308
3. MikroElektronika RN4871
4. SparkFun Bluetooth LE Long Range Module 

These are some of the best long-range Bluetooth modules currently available. However, the actual range of a Bluetooth module also depends on the environment in which it is used. For example, it’s typically shorter in an urban area with many buildings and infrastructure. The ideal module will depend on specific needs and applications. 

Fanstel BT832XE

The Fanstel BT832XE is a Bluetooth 5.3 module with a range of up to 1350 meters and an external +6 dBi antenna (the range can also be extended by using the external antenna). It’s based on the nRF52832 chip and is ideal for industrial automation, asset tracking, and remote monitoring applications. Overall, the BT832XE and BT832X offer improved range, speed, and efficiency. 

The Fanstel module operates on a supply voltage of 3.3~4.2V, with a power consumption of 100 microamperes in active mode (it’s reduced to one microampere in sleep mode). The BT832XE low-power design makes it ideal for battery-powered applications. The module can operate in a temperature range of -40˚ to 85˚ C. It weighs only two grams and dimensions of 25 x 17 x 3 mm. 

The BT832XE is available in various packages, including a development kit, a module, and a breakout board. The development kit includes the module, an antenna, a USB cable, and software. The module is a ready-to-use solution that can be easily integrated into an application. The breakout board provides access to all of the module’s pins, making connecting it to other devices easy.

Semtech SX1308

The Semtech SX1308 is a Bluetooth Low Energy (BLE) radio transceiver module having a range of up to 800 meters with an external antenna. It’s ideal for asset tracking, remote monitoring, and environmental sensing applications. 

This 25 x 17 x 3 mm chip has operating frequencies of 868 MHz, 915 MHz, or 2.4 GHz, with an operating voltage of 3.3~5V.  The module offers data rates up to 2 Mbps for up to 800 meters. Its power consumption ranges from 100 microamperes in active mode to one microampere in sleep mode. The chip weighs two grams. The operating temperature range is -40˚ to 125˚C.  

Semtech SX1308 is a digital baseband chip that’s designed to offer breakthrough gateway capabilities in the ISM bands worldwide. It integrates the LoRa concentrator IP, which allows it to support LoRaWAN communication. However, it’s not a LoRa module. Some LoRa modules include the SX1308 chip and components such as an antenna, a power supply, and a microcontroller. As a ready-to-use device, it can be easily integrated into a LoRaWAN application.

MikroElektronika RN4871

The MikroElektronika RN4871 is a Bluetooth Low Energy (BLE) module for easy integration into embedded systems. Based on the Microchip RN4871 chip, this MikroElektronika module supports Bluetooth 5.0. and offers a range of up to 600 meters with an external antenna. 

The GATT (Generic Attribute Profile) profile allows the RN4871 to exchange data with other Bluetooth devices. It uses a GATT Client to connect to and interact with other Bluetooth devices and a GATT Server to share its services and features with other Bluetooth devices. The protocol also allows the RN4871 to participate in a mesh network, creating a low-power, low-cost network of devices.

The RN4871 is 12 x 15 x 3 mm and weighs about two grams. Its operating voltage is 3.3V, and its power consumption ranges from 100 microamperes to one microamperes. The module offers a data speed of 2 Mbps to up to 600 meters with an external antenna. The operating temperature range is -40˚ to 125˚C. 

This module is ideal for smart homes, industrial automation, inventory management, customer tracking, medical implants, wearables, asset tracking, and fleet management applications.

SparkFun Bluetooth LE Long Range Module  

The Sparkfun NanoBeacon module offers the InPlay IN100 NanoBeacon Bluetooth 5.3 beacon SoC, a Qwicc connector, and GPIOs. Designed to work with Bosch Sensortec BME280 3-in-1 humidity and the BMA400 ultra-low power accelerometer sensors, the IN100 NanoBeacon SoC offers an extended range of up to 500 meters with an external antenna. Based on the nRF52832 chip, this module supports Bluetooth 5.0. 

The basic version of this breakout is made for mass production but lacks a reset button and power LED. However, it has male headers connected to the board’s through-hole pins. The Lite version is made for prototyping and has a reset button and power LED. It’s ideal for applications like indoor positioning, geofencing, asset tracking, inventory management, and delivering targeted marketing messages.
