Purchasing and Licensing

  1. Click Settings and more button () and select Purchase license... (or Activate License... depending on the version of the software you are using) from the menu.
    This will lead you to the license purchasing web page.
  2. If you are using an old version of the Bluetooth Battery Monitor, Activate License... item may not be in the menu.
    If this is the case, please select About... and click Visit activation page link in the opened dialog box instead.
This method may not be suitable for everyone. Please use this method only if you understand what you are doing and feel comfortable about the steps.

Yes, you can. Please follow the steps listed below.

  1. Start the license purchase process from the PC.
  2. A web browser window opens and fails to show the license purchase page because your PC is not connected to the Internet.
  3. Copy the URL in the address bar to a file.
  4. IMPORTANT: Altering the URL may cause the generation of an invalid license file.

  5. Copy the file to another PC that has an Internet connection.
  6. Open the URL with a browser and continue the purchase process.

Type of the license we currently offer is perpetual. You pay once and the license is valid forever.

IMPORTANT: This does not mean that the software is guaranteed to work with future versions of the operating systems.

After completing the purchase process and your payment is verified, you will receive the license file via email. Once you receive the license file, please:

  1. Save the license file (which is attached to the email) to your PC's local disk.
    • Make sure that you will not modify it. Even the slightest modification will make the license file invalid.
    • Please save the license file to a safe location. You will need it when you re-install the program.
  2. Click Settings and more button () and select Apply Purchased License File... from the menu.
  3. If you don't see Apply Purchased License File... in the menu (which happens if you are using old version), please select About.... Then, click Apply activation file link in the About dialog box.

  4. Select the license file and click on Open button.

Unfortunately, no. You need valid license for each computer you activate.

But we offer a discount for additional licenses. When you activate additional computer, please enter the e-mail address you used to activate the first computer. Current discounted license is $2.99.

Unfortunately, the license is tied to the specific hardware (more specifically, to the motherboard) and not transferable to another computer.

We wish we could make it transferable, but doing so requires much more resource (development effort and maintenance cost) and, as a result, increases the license fee.

So, we decided to keep it simple, and instead of that, provide a discount for the additional computers. We hope it will make up for the lack of transferability. If you want to take advantage of that, please start the license purchase process from your new computer and look for the “Discount for additional license” section (bottom half) of the page.

We currently accept Debit/Credit cards, PayPal and Alipay.

If these methods are not available in your country and/or you have a recommendation to another payment method, please let us know.

First of all, thank you for purchasing the license.

You should receive a license file in an e-mail from support@bluetoothgoodies.com soon after the payment is completed. If you do not receive the e-mail in one hour, please:

  1. Check PayPal payment transaction status.
  2. Please check the e-mail from PayPal or login to your PayPal account and check the status of the transaction first. Sometime transaction remains in "pending state" for some time (up to couple of days). If this is the case, we cannot issue license until the transaction's state changes to "complete".

  3. Check if the e-mail was mistakenly marked as a SPAM mail.
  4. Unfortunately, an e-mail sent from a small company like us using an automated system that has an attachment are often considered suspicious and marked as a SPAM mail.
    Please check your junk/spam mail folder.

    This problem seems to happen more frequently if you are using Microsoft's e-mail services such as outlook.com or hotmail.com.

  5. If you don't find it in your junk mail folder, please contact us.
  6. We will get back to you as soon as possible. Please allow us up to one business day to respond.

Troubleshooting

This FAQ topic applies to all classes of Bluetooth devices. If you are having a problem with audio devices (including headsets, headphones and speakers), please check another FAQ topic first.

  1. Make sure that your Bluetooth device is paired to the computer where Bluetooth Battery Monitor is running
  2. Turn off your Bluetooth device and turn it back on
  3. Many Bluetooth devices don't report their battery level frequently. Toggling device power usually forces such Bluetooth deices to send the report and helps Bluetooth Battery Monitor to show the information.

  4. Check if your Bluetooth device is capable of reporting its battery level
  5. Bluetooth Battery Monitor is not a magic program. It relies on each Bluetooth device to report its battery level.

    If you have a smartphone that can show Bluetooth devices' battery level (iPhones and many new Android phones can), please try with it.

    You can also find "rule of thumb" battery level support in the other FAQ item – Does my Bluetooth device have a capability to report battery level?

  6. Still having a problem?
  7. Please contact us using the contact form. Please make sure to include the following information.

    • Name of the device as it appears in the Windows user interface.
    • If you have verified the device's capability of reporting battery level and, if so, with which smartphone.
    • If you are willing to help us by collecting additional information if it is necessary.

Bluetooth Battery Monitor requires Bluetooth adapter of your computer to be in the active (working) state to:

  • Properly install the software.
  • Recognize the new Bluetooth devices.
  • Get the up-to-date battery level of the Bluetooth devices.

If you see the warning message about disabled Bluetooth, please turn on the Bluetooth adapter with the following steps.

1. Click the Action Center icon located on the right-hand side of the taskbar. Click the Action Center icon
2. If the buttons are collapsed and the Bluetooth button is not shown, click the Expand link. Click the Expand link
3. If the Bluetooth button is gray, it means Bluetooth is turned off. Click the button to turn it on. Click the Bluetooth button
4. When the Bluetooth is on, the Bluetooth button is highlighted. Button is highlighted when Bluetooth is enabled

Bluetooth Battery Monitor relies on each Bluetooth device to report its battery level. But, not all Bluetooth devices have that capability. Device manufacturers usually do not advertise this feature either. As a result, when a device is not recognized by the program, it is hard to tell which to blame – device or program.

This FAQ item provides "rule of thumb" about Bluetooth device's battery level support so that you will be able to decide which to suspect in case of a problem.

Phones, Tablets, PCs
These devices do not report battery level via Bluetooth.
Audio devices (such as headphone, headset or speaker)

Battery level information is communicated through Hands Free Profile (HFP). Most Bluetooth audio devices support HFP, but some (such as speakers or Bluetooth to analog converter) do not support it, hence no battery level reporting for them.

Bluetooth Classic HID (Human Input Devices – such as keyboard or mouse)

If your HID device is a Bluetooth Classic device, the chance that it reports battery level is not so good. Bluetooth Battery Monitor's anonymous usage data shows that only 10 to 20% of HID devices report battery level using well-known method.

It is also known that some major companies (namely Apple and Logitech) use proprietary method to report battery level. Current version of Bluetooth Battery Monitor does not support them, but future version might do.

Update: Starting version 1.3.0, Bluetooth Battery Monitor supports most of the Logitech keyboards and mice.

Bluetooth Classic Game Controllers

Technically, game controllers are the part of the HID devices and there is a well-known method to report battery level. If your game controller uses that method, Bluetooth Battery Monitor should be able to support it automatically. But, so far, we have not seen any Bluetooth game controller that uses well-known method.

Sony Dualshock 4 and Microsoft Xbox One controller do implement proprietary methods to report battery level. Starting version 1.3.0, Bluetooth Battery Monitor supports Dualshock 4 controller. Xbox One controller support might be added in the future version. If you are interested in Xbox One controller support, please contact us.

Bluetooth Low Energy (Smart) Devices

Generally speaking, you can expect much better battery level reporting support with Bluetooth Low Energy devices. Most Bluetooth Low Energy HID devices (such as keyboard, mouse and pen) do support battery level reporting.

In addition, unlike Bluetooth Classic devices, Bluetooth Low Energy devices have a definitive way to check its battery level reporting capability.

  1. Open device manager.
  2. Select View menu > Devices by connection
  3. Locate the Bluetooth LE device in question in the tree view
  4. Look for the Bluetooth LE Generic Attribute Service node(s) under the Bluetooth LE device node. (Fig.1)
  5. If there is no such node, this Bluetooth LE device does not report battery level.

    If there are one or more such nodes, repeat the following steps for each node.

    1. Double click the node to open its Property dialog box.
    2. Select Details tab.
    3. Select Hardware Ids property.
    4. Check if the Value contains ...{0000180f-... (Fig.2)

    If you find a node with ...{0000180f-..., this device can report battery level.

Fig.2 Hardware Ids property values

Bluetooth audio devices, such as headphones, headsets, and speakers make two types of connections. One is called A2DP (also known as "headphone", "music", or "media audio") and the other is called HFP (also known as "hands free", "headset", "voice", or "phone audio"). As the name suggests, HFP is used when you make a phone call, but it's not the only role of the connection. Audio device uses an HFP connection to transmit its battery level information. Because the A2DP connection doesn't have that capability, you need an HFP connection to monitor the battery level even if you do not use your device for a phone call.

To check which connection is established between your audio device and Windows 10 PC, please open the Bluetooth control panel. If you see "Connected voice, music", it means HFP and A2DP connections are established. On the other hand, if you see "Connected music", it means only A2DP connection is established and you cannot make phone call or read battery level of this device. If this happens to your device, please check another FAQ topic.

(If you are not familiar with HFP connection, please check the FAQ about HFP first.)

One of the most common reasons for this problem is:

  • Your audio device's A2DP is connected to your PC. So, you can listen to music through it.
  • But, your audio device's HFP is connected to another device, such as your phone.
  • And, your audio device can make only one HFP connection at one time (device's limitation).
  • As a result, your PC cannot establish an HFP connection with your audio device and fails to obtain battery level information.

This problem can be addressed in several ways.

1) Unpair from the other device

If you don't need to connect the audio device to the other device, this is the most straight forward solution.

Limitation: Obviously, you cannot use this solution if you occasionally need to use the audio device with the other device.

2) Prevent the other device from making an HFP connection

If you don't need to use the HFP connection with the other device (i.e. you don't make a phone call using the audio device), you may be able to permanently disable the HFP connection between the audio device and the other device.

Exact steps may vary depending on the device, but if you are using Android:

  1. Open Bluetooth Settings.
  2. Open "Device details" of the audio device (tap on the gear icon).
  3. Uncheck "Phone calls".

Limitation: You cannot use this solution if you need to use the audio device to make a phone call through the other device.

3) Manually disconnect the audio device from the other device

After manually disconnecting the audio device from the other device (you can do it from the Bluetooth settings page of the other device or turning the Bluetooth of the other device off), your PC can take back the HFP connection.

Limitation: Your PC may get an HFP connection temporarily, but there is no guarantee that, when the audio device reconnects, your PC can get the HFP connection automatically. If it fails to do so, you need to repeat this operation.

4) Use a multipoint capable device

This problem occurs because your audio device cannot make multiple HFP connections at one time. This is a limitation of the device you are using and not all Bluetooth audio devices have this limitation. Many Bluetooth audio devices (often marketed as "multipoint" devices) can make multiple HFP connections at one time. If you want to seamlessly share the audio device with your PC and another device, this is the best solution.

(If you are not familiar with HFP connection, please check the FAQ about HFP first.)

By default, Windows enables HFP for all Bluetooth audio devices, but if Bluetooth Battery Monitor's Troubleshooter led you to this FAQ topic, it's disabled on your computer. Please follow the steps below to enable it.

1. Go to the Windows search bar and type "mmsys.cpl" (without double quotes) and hit ENTER. This will open a Sound control panel. Then, select the Playback tab.

2. Right-click on the device list area and enable Show Disabled Devices option and Show Disconnected Devices option in the popup menu.

3. Look for Headset or Bluetooth Handsfree Audio (or similar name) icon for your Bluetooth audio device. (Black down arrow means the device is disabled) Then right-click on the device and select Enable in the popup menu.

4-1. If the black down arrow on the icon disappears and the icon is not grayed, it's ok. You may or may not see a green mark on the icon, but it's ok either way.

4-2. If the black down arrow on the icon changes to a red down arrow, it means Windows tried to establish a connection but for some reason, it failed.

If this is the case, please continue to the other FAQ topic – How to connect disconnected HFP connection

These devices usually do not report their battery information and, to monitor them, you need to install software on them.
