In The Hand LtdBluetooth is Big, Really Big Looking back over the different functionality I’ve covered in these past few posts has highlighted that Bluetooth is used for a wide range of scenarios, and it has grown massively from its simple beginnings. It is fair to say that looking at the evolution of each specification version that more […]
When we last looked at Bluetooth Low Energy we looked at the code required to read the battery level from a device. There are two things we didn’t cover – writing values and sending commands to a device. Writing in the Air If you’re familiar with the service that you are writing to the process […]
Bluetooth Classic contains a handful of profiles which use AT commands to work with telephony devices over an RFComm connection. We discussed these briefly in #3 of this series and today will look in more detail and the most commonly implemented one – Hands Free Profile. Look No Hands! Two similar profiles exist in Headset […]
Both Classic and Low Energy devices can provide functionality to unpaired devices or require pairing first before exchanging sensitive information. However, what exactly is pairing? Stick a Pin in it The original mechanism for pairing uses a four digit PIN code. One device would need to be discoverable, and the other device upon discovering it […]
Following on from the last post, which covered the technology of Bluetooth Low Energy, this post will look at how to use it from code using InTheHand.BluetoothLE. We’re going to look at an example using a simple but widely used service – Battery Service. You can probably guess what it is used for. Step One […]
In 2011, Bluetooth 4.0 was introduced and contained the biggest update to the standard yet. It introduced a whole new way of talking to Bluetooth devices which allowed them to use considerably less power. Bluetooth Low Energy works entirely separately from Bluetooth Classic but the two can coexist. For example most mobile phones will support […]
I managed to complete one of those jobs I’d been meaning to get around to for sometime and to celebrate getting the to-do list down to triple figures I thought I’d share the good news! Many years ago I built the documentation for 32feet.NET combined with the other libraries I had at the time:- Pontoon […]
Yesterday’s release of Home Assistant 2022.8 adds built-in Bluetooth support. This allows multiple integrations to share common functionality and (important for non-Linux platforms) share a single Bluetooth adapter. In the release are five integrations built on top of this support, along with Apple HomeKit support for Bluetooth devices (even if you don’t have an Apple […]
Okay, now I’ve drawn you in with a click-bait headline I need to clarify a little! For some time now Windows 10 has had a tightly integrated app called Phone Link (previously Your Phone) which allows you to interact with your phone from the desktop. However, it doesn’t cater for the 50-odd percent of users […]
Microsoft have already announced that Bluetooth HID (keyboard) support is finally coming in Windows 10, but it was quietly added in Windows Phone 8.1 GDR2. The problem is this update won’t be circulated to most phones. It is however present on the new Lumia 640 series. It’s very easy to setup a Bluetooth Keyboard with […]
