Bluetooth battery status3/2/2023 ![]() Once two devices are connected, they are free to communicate over a wide variety of communication profiles. Under the Bluetooth Specifications, devices broadcast their MAC address as a unique identifier. Therefore, this is now simpler as both the classic and LE protocols operate at the standard 2.4GHz frequency, meaning they can use the same antenna internally. Since about 2012 most mobile phone manufacturers have provided devices capable of both Bluetooth classic and Bluetooth LE communication. ![]() Bluetooth LE has been designed to consume considerably less power than the classic Bluetooth protocol. One of the largest factors in the prevalence of small Bluetooth enabled devices is the advent of the Bluetooth LE protocol. Just A Quick Mention of Bluetooth LE Protocol Some popular examples of these devices are Bluetooth headphones, health monitors, insulin pumps and even tracking devices. This allows users to control and interface with these peripherals via their phone. More and more we are seeing small low power devices being integrated with Bluetooth. Most of us are familiar with the Bluetooth communications protocol. While this problem may seem simple, for the uninitiated in Bluetooth technology and the nuances of its implementation within Xamarin, there are many factors which need to be addressed. It would be able to communicate over Bluetooth LE to another device. We planned to build a mobile app to target an Android device with a minimum OS version of 4.3 (API Level 18). Basically, nothing more than sending a few bytes of data between the phone and the remote device. The primary function of the mobile app was to communicate with a Bluetooth Low Energy (Bluetooth LE/BLE) device. Here at Enigma Mx, we were recently given the opportunity to work with a client on building a mobile application. All of these devices are capable of reporting battery information, but Microsoft's "Bluetooth Mobile Mouse 3600" is the only device Windows 10 can display the information.How to integrate Bluetooth LE in Xamarin Forms The Xamarin Forms and Bluetooth LE Project Introduction: I also tested the latest Insider preview release for the 19H1 update (build 18252), but it's the same as 1809. But most other devices including headphones, headsets, and Classic mice/keyboards are not supported by Windows 10 and 3rd party software is still needed. If you are using Bluetooth LE mice/keyboards, those devices are probably OK. Windows 10 update 1809 is finalized (build 17763) and I think it's a good time to clarify what it does and what it doesn't.Īs far as I've tested, it supports only Bluetooth LE (Low Energy) devices that use GATT Battery Service to report battery information. So, you can access GATT of LE only devices (such as HID devices), but you cannot access your headphone/headsets's GATT because those devices are connected with Classic only. If your device's vendor doesn't provide such application, you may want to try "Bluetooth Battery Monitor", which is available at: Bluetooth Battery Monitorįull Disclosure: I'm the author of the program.īy the way, you mentioned about GATT battery service, but Windows (again, at least as of 3) supports GATT access only over LE connection, and doesn't allow simultaneous LE/Classic connection either. I saw Microsoft and Logitech do so for their keyboard/mouse products. Some major Bluetooth device vendors provide companion application and it shows battery level. So, to monitor Bluetooth devices' battery level on Windows 10, you do need to install additional software. In Windows 10, they were replaced by Microsoft's code and it doesn't (at least, as of 3) have capability to show battery level for any type of Bluetooth device. That's why some people say that it's supported by Windows, but it may not be the case for everyone. ![]() Some of them did support battery level display for some type of devices (there are multiple way to report battery level). In Windows 7, part of the Bluetooth stack was provided by 3rd party (such as Widcomm, Toshiba, etc) add-on software. How can I get the battery level of my Bluetooth headphone over a Windows PC? ![]()
