In this article, we will walk you through the process of checking your Bluetooth version on an Ubuntu laptop using the command line. This can be particularly useful when troubleshooting connectivity issues or when you’re trying to determine if your system supports a particular Bluetooth device.
To check the Bluetooth version on an Ubuntu laptop from the command line, you can use the hciconfig -a command to display the Bluetooth version of your laptop. Additionally, you can check the Bluetooth version of a peripheral device by pairing it with your laptop and using the hcitool info <mac address> command.
Introduction
Bluetooth technology has evolved significantly over the years, with newer versions offering improvements in range, speed, and power consumption. Knowing the Bluetooth version of your Ubuntu laptop can help you optimize your Bluetooth devices’ performance.
Prerequisites
Before we get started, ensure that you have:
