Help the community by sharing your opinion.Many tutorials on the internet are done with command-line tools with the now deprecated tools of hcitool and hcidump.

This 'HowTo' looks at how to scan for beacons without using those tools. The go-to tool when using Bluetooth from the Linux command-line is bluetoothctl.

It is also a good idea to clear all filtering options. My session looked like this:. For example:. In this example it has not made any difference. However, if you have other Bluetooth devices advertising nearby it will be very helpful to reduce how much is reported.

To view all the activity on the RPi's Bluetooth controller there is a Bluetooth monitoring tool from BlueZ called "btmon".

This has a very verbose output as it does tell us everything that is happening with the Bluetooth controller and is typically used for debugging low-level issues. With bluetoothctl scanning in the first terminal, btmon will report such things as an "LE Advertising Report" which will contain information about nearby devices that are advertising. Our beacon should be in amongst all the output in btmon. This is because the BlueZ tools are filtering duplicate adverts.

This is done because of concerns about the machine resources being consumed in doing such activity. The BlueZ project has deprecated the command-line tool hcitool that did allow this. This is because the tool used the Host Controller Interface HCI which is a very low-level interface and did not protect the user from being able to do very bad things to their system.

The new BlueZ tools give the user more protection however it does mean the tools do not report duplicates. Some of the Bluetooth libraries that act as scanners can read all beacon broadcasts. One of the best Python libraries I've found for scanning for beacons is aioblescan. Much of what is described above should work for any BLE beacons. I've focused on Eddystone as it is an open specification and most widely supported. One interesting place that has Eddystone support is the MakeCode editor for micro:bit which supports very easy access to programming Eddystone beacons.

Jos Ryke josryke has posted on Twitter a great summary on how the packets vary between the different beacon types.Add the following snippet to your HTML:. Here's a python example to get you started! Read up about this project on.

In this short tutorial, you will learn how to setup the BeagleBone Green Wireless BBGW for Bluetooth use and create a simple Python script that will trigger an LED to light up when a known Bluetooth-capable device such as your phone or fitness band comes within sensing range.

This demo should be used as a simple starting place for creating systems that require the ability to track or sense known users by their handheld Bluetooth devices. Make sure you are running the latest firmware image for the device. B e sure to use only the images named bone-debian As the platform matures the most up-to-date image will be moved to the official wiki page bu t for now use the latest testing build.

For more information about updating the BeagleBone Green firmware or flashing the eMMC to free up a microSD card, check out the official page on the matter here. In order to proceed, you will require net access so be sure to read section 3.

Before starting any system setup, it is always a good idea to have the latest stable software installed. Now it is time to install the Bluetooth library prerequisites required by pybluez. Finally use the Python package manager to install our Bluetooth framework. With all the libraries and dependencies installed it is now time to finally start up our Bluetooth chipset on the BBGW. This is a little built-in script for wireless-capable BeagleBone models that discovers Bluetooth hardware and sets it up for use.

Head down to the schematic section for an image of how to insert the LED. In general, what we want is a simple loop that requests information from a known Bluetooth device ID and, depending on what it hears back, changes the state of a digital output pin accordingly. The neat thing about polling for public Bluetooth information, we no longer have to worry about pairing with the desired device!

This greatly reduces the complexity of the system down to something that can be implemented in just a few lines of code. To make the script a bit easier to use, I've added some helpful user prompts and a device discovery stage to make identifying your Bluetooth device easier. To see how it works, either run it in cloud9 or just use:. After following the onscreen instructions, the script will then proceed to ping your device for information every few seconds.

Try walking away from the BeagleBone and walking back to see what the detection range is for your specific device. The LED, despite being tradition for intro tutorials, makes it pretty easy to tell what the current detection state is from a distance.

Here's what a typical demo session looks like in terms of debug output:. For my phone, I had to get around 12 feet away before the BeagleBone lost connection and when coming back into range, there were a few false negatives. The script above is just meant as a quick working example of a detection method that doesn't require device pairing. I'll leave the reader with some ideas on how it can be expanded for use in a more serious system. Log in Sign up. Simple Bluetooth Device Detection.

Thread starter Jarret B Start date May 29, Jarret B Active Member Staff member. Credits Bluetooth is a wireless technology mainly for close range.

Most devices have Bluetooth ability such as smart phones, speakers, headphones, laptops, keyboards, mice, printers gaming consoles, etc. Having a basic understanding of Bluetooth will help you when dealing with the devices. In connection, the Bluetooth standard would bring together multiple various devices to communicate together. Bluetooth uses the 2.

The initial Bluetooth standard was created to replace RS connections with a wireless method. Bluetooth allows for a connection of seven devices. For example, headphones may initiate a call from a smart phone. A round-robin method is used as needed.

How To Lock/Unlock GNOME Desktop Using a Smartphone

The round-robin method is where each device is communicated with one after another in succession. Bluetooth Communications Packets are sent by Bluetooth on channels.

On the used band each channel is 1 MHz from the next channel making for a total of 79 channels. Around packets can be sent in a second.

Each slot is micro-seconds. Bluetooth Classes Each Bluetooth device may be listed under a specific Class. The Class is not to be confused with the Bluetooth Version which describes the protocol standards and abilities. The Class is mainly used to specify the hardware ability for connection range.One of the most basic and common security measures that you can adopt in your working environment is to protect your computer by automatically locking the screen after a certain period of inactivity, so that it is necessary to enter a password to unlock.

But there is a more effective way, and that is to configure your Linux machine so that the distance or proximity of a Bluetooth device you own, for example your cell phone or a smartwatch, automatically causes locking or unlocking the screen without having to enter any password on keyboard. In an ideal world you would always remember to lock the screen when you leave your workplace to prevent another person from manipulating your computer during your absence. However, sometimes it will happen that you will neglect and forget to do socompromising your information security.

But even though you always remember to lock the screen, unlocking it regularly over and over again in the presence of other people or in uncontrolled environments is also a major security risk, as you will be exposing your password every time you type iteither because someone next to you sees you writing it or because a surveillance camera records the password you enter on your keyboard. Thus, with the solution I propose here you will minimize both risks: forgetting about manually lock the screen and exposing your password every time you type it.

Blueproximity is an application that constantly monitors signal strength of a Bluetooth device linked to your computer, so that if you move away from your workplace carrying your smartphone and the signal strength falls below a given threshold for a given period of time both parameters can be configured as you likea command of your choice will runnormally one whose purpose is to lock the screen.

Otherwise, when the signal level recovers because you get closer to the computer, the screen unlock command will be executed without you having to do anything. Installing Blueproximity application is very easy because there are packages available for main Linux distributions and they can be installed in the usual way:. The third command in the configuration dialog box Proximity command runs periodically according to the selected time interval as long as your Bluetooth device is within range.

This can be used to run a command that simulates user activity so that the session will never be locked even if there is no user activity but you are nearby. You can use here just the same command as for unlocking.

Blueproximity is originally a Gnome application, so by default it will be configured with the following commands:. In this case there are two commands because the second one corresponds to older versions of KDE prior to version 4. If your computer has a physical button to enable or disable Bluetooth then it is the Hard blocked parameter which could be set to yes. In other cases, even if you unblock the driver, it remains off power off.

This happens for example if you are working on a laptop that is not plugged into its power adapter and is running on battery. It may happen that the power-saving settings that your Linux distribution brings by default cause the Bluetooth driver to power off automatically when the system boots and you have to power it on by hand:. Since the above command is interactive, you might better prefer the following one that will not require any user intervention so it can be used within a script:.

There are other interesting things you can do when your linked Bluetooth device is approaching or moving away from your box other than locking or unlocking the screen. You can configure Bluproximity to run more sophisticated locking and unlocking commands, or even create your own scripts to do many things at once. Here are some ideas that may be useful:. Apart from performing locking or unlocking, the screen can also be turned off when you move away and turned on again when you approach in order to save energy.

Sounds nice and easy, will try it immediately.Even so, I always lock my laptop before I go grab another drink, if only to stop anyone posting something to my social media! It requires various feats of finger-flexing aerobics to enter correctly. I always fudge typing it, having to retry again.

Is it security prudent? Heck no! Consider this app a curio, an interesting thing to play around with, rather than a viable, predictable or even sensible unlocking mechanism.

BlueProximity is an old, old app. It is crazy how many people forget to do this step! Follow the on-screen prompts for the rest. To fetch it via the command line run:. You can get it to show up, however, by using a third-party patch. This should hopefully list connected Bluetooth devices. Here is where you set up how close your device has to be in or out of range to trigger the lock screen. If this line is maxed out at it means something has gone wrong and you need to skim back a few steps and reconnect.

To unlock I simply need to move my device to within 2 metres of my laptop. Refer to the Blueproximity manual for more detailed instructions, and be sure to share your own experiences — and frustrations — in trying to get it to play nice with modern Linux distributions. Tweet Share 0 I work out of a coffee shop most days. I wondered if there was a similar app or tool for Linux. Apps How To.Author : Andrew Posted: May 24, Tagged with: blueproximity Bluetooth linux mobile ubuntu.

You can configure the proximity distance this is just an approximation because the signal strength is not always the same and duration and when you move away from your computer, the screensaver is triggered and your computer is locked. When the bluetooth device phone is in range, it automatically unlocks the computer, without requiring any input on your side.

This is useful for instance if you use Linux at work and want your computer to lock automatically when you leave for a few minutes, etc. Install BlueProximity. Ubuntu If you want, you can whitelist all applications to use the Systray - see this post for details. Install Dconf-Tools. Enable bluetooth on your device and make sure it's discoverable usually there's an option for this in your phone's settings.

After a few seconds, your phone should show up in the list - add it to BlueProximity:.

You can then tweak the settings in BlueProximity Preferences but the default settings should be enough and your computer should now automatically lock when you move away from it. Don't worry though: if you forget your device, you can still unlock the computer by entering you password as usual. You can also pause BlueProximity by right clicking the icon on the notification area and selecting "Pause".
