Bluetooth tasks with Termux changed how I handle my connections—no more manual toggles.
I used to waste five to ten minutes a day fumbling through Bluetooth menus—connecting headphones, switching to car audio, forgetting to turn it off again.
Multiply that over a week, and you’re looking at hours lost to button taps and swipes. That’s when I discovered the power of Bluetooth tasks with Termux—and everything changed.
In the spirit of FOSS, I set out to automate these mundane Bluetooth interactions using nothing but a terminal emulator, some shell scripts, and the mighty Termux. No root, no bloatware, just pure command-line magic.
If you’ve ever wished your Android could “just do it” when you walk into your room or start your car, you’re about to meet your new favorite workflow.
Let’s build something powerful, local, and open. Keep reading.

The steps outlined in this article were based on my personal setup and were working at the time of writing. Due to the ever-changing nature of Android, Termux, and package support, your experience may vary. Termux has limited or no native support for certain hardware features like Bluetooth, depending on your device and Android version. Use these instructions as a reference, not a guarantee.

How Bluetooth Works on Android (Without Root)
Before we automate Bluetooth tasks with Termux, it helps to understand what’s going on behind the scenes. On Android, Bluetooth is managed by system services that require elevated permissions to control directly. Without root, you won’t be able to access everything, but thanks to the Termux:API add-on and Activity Manager (am) commands, we can interact with many core functions safely.
For example, am start
allows us to launch Bluetooth settings or even simulate taps, while svc bluetooth enable
can toggle Bluetooth on and off. These aren’t Termux-specific—they’re built into Android—but Termux gives us a programmable terminal interface to string them together in powerful ways.

Getting Started: Installing Termux and Required Tools
Before diving into Bluetooth tasks with Termux, let’s set up your environment. This guide assumes you’re working with an Android device that doesn’t require root access—just your thumbs, your brain, and a love for open-source tools.
Prerequisites
Before you start automating Bluetooth tasks with Termux, ensure you have the following:
- An Android device with Bluetooth capability.
- Termux installed from the Google Play Store or F-Droid.
- Basic familiarity with using Termux and shell scripting.
Step 1: Install Termux
To begin automating Bluetooth tasks with Termux, you need Termux installed. If you haven’t done this yet:
- Open the Google Play Store or F-Droid.
- Search for Termux.
- Install and open the app.
Termux provides a Linux environment that’s essential for scripting and automating tasks on your Android device.
Step 2: Update Termux Packages
Updating Termux packages ensures that you have the latest tools and security patches. Run the following command in Termux:
pkg update && pkg upgrade
This prepares your environment for installing additional tools needed for Bluetooth automation.
Step 3: Install Required Tools
To automate Bluetooth tasks with Termux, you need to install some essential tools. Start by installing bluez
and blueman
:
pkg install bluez blueman
bluez
provides Bluetooth management tools, and blueman
offers a graphical Bluetooth manager.
Step 4: Install and Configure bluez
bluez
is a Bluetooth protocol stack for Linux that includes utilities to manage Bluetooth devices. To install and configure bluez
, use the following commands:
pkg install bluez
Configure bluez
to suit your automation needs. For example, you might need to set up Bluetooth permissions and configurations in Termux.
Step 5: Automate Bluetooth Tasks with Scripts
Now you can create scripts to automate various Bluetooth tasks. For instance, you can write a script to turn Bluetooth on or off, connect to a specific device, or scan for nearby devices. Here’s an example script to turn Bluetooth on:
#!/data/data/com.termux/files/usr/bin/bash
# Script to turn Bluetooth on
bluetoothctl power on
Save this script as bt_on.sh
and make it executable:
chmod +x bt_on.sh
Similarly, you can create scripts for other Bluetooth tasks, such as connecting to devices or handling Bluetooth profiles.
Step 6: Create and Schedule Scripts
To run your Bluetooth automation scripts at specific times or intervals, you can use cron
or Termux:Tasker
:
Using cron
:
Install cronie
for scheduling tasks:
pkg install cronie
Edit the cron jobs file:
crontab -e
Add a cron job entry to run your script at a desired time. For example, to run bt_on.sh
every day at 8 AM:
8 * * * /data/data/com.termux/files/home/bt_on.sh
Using Termux:Tasker
: Integrate with Tasker to schedule and manage tasks more visually.
Step 7: Testing Your Automation
Test your automation scripts to ensure they work as expected. Run your scripts manually to verify functionality:
./bt_on.sh
Check for any errors and make necessary adjustments to ensure reliable automation of your Bluetooth tasks.
Step 8: Troubleshooting
If you encounter issues while automating Bluetooth tasks with Termux, consider the following troubleshooting steps:
- Ensure that Bluetooth permissions are correctly configured.
- Check script permissions and paths.
- Verify that
bluez
and other required tools are properly installed.
Refer to Termux and Bluetooth documentation for further assistance if needed.
