bluetooth

问题 I am developing an Android app which behaves as Bluetooth peripheral role with a service. When I start advertising, other Android devices searching for devices offering this service, can see my device (and can pair to it without pin) - ok. But how to enable PIN pairing? 回答1: You can force the device has to be paired, when using specific characteristics by protecting them with PERMISSION_READ_ENCRYPTED_MITM or PERMISSION_WRITE_ENCRYPTED_MITM. The client/central side can force pairing by

问题 I tried to search for an answer for my query. It seems trivial, but I cant find an answer yet. I am trying to run a program using Qt Bluetooth on iOS. I am able to use it successfully on MacOS. But even the most basic feature of code like : QBluetoothLocalDevice localDevice; QString localDeviceName; // Check if Bluetooth is available on this device if (localDevice.isValid()) { // Turn Bluetooth on localDevice.powerOn(); // Read local device name localDeviceName = localDevice.name(); // Make

问题 I decided to build a tool to display the battery level of a pair of Bluetooth headphones, since I got this feature on Android, but not on Windows. For some reason, it just doesn't display in the settings. I'm using UWP and with the Device Enumerator I managed to pull a list of connected devices. Is there any way to get the battery level from this point? I've seen that people are using RFCom or GATT, but their issue involves connecting to the device, which I think is redundant since the tool

问题 I'm currently working on an Android app for a proprietary Bluetooth Low Energy device. I decided to use RxAndroidBle and I'm happy with it's relative ease of use compared to the built-in bluetooth stack. Where I'm running into problems: I need to subscribe to two characteristics and continuously read and aggregate their values. Looking at this example page, http://polidea.github.io/RxAndroidBle/, I have been able to read multiple characteristics as per the example, but have been unsuccessful

问题 If I set AudioManager mode to MODE_IN_COMMUNICATION, and set the Media Player stream to STREAM_VOICE_CALL, I can route the audio to the speakerphone or the internal handset speaker just fine. And if it's routed to the internal speaker, and a wired headset is plugged int, it automatically routes to it. However, I can't figure out a way to route the audio to an A2DP headset (without changing the audio mode to MODE_NORMAL, or the stream to STREAM_MUSIC). My problem is that using MODE_NORMAL and
