问题 I would like to receive an event for detecting whenever bluetooth gets paired or unpaired in my device. In the beginning i found http://developer.android.com/reference/android/bluetooth/BluetoothServerSocket.html. I followed this blog : http://android-er.blogspot.co.il/2014/12/make-bluetooth-connection-between.html which is quite usefull, but, isn't detecting when a new connection is made. Needless to say, I have no use for bluetooth implementation, which i'm well aware of : final

问题 On My Addroid app I'm trying to add some extra data when I try to start ble advertising, and as I've read, advertise data must be <= 31 bytes. That's how I do it: var testData = "abcdefghij" var data = AdvertiseData.Builder().apply { addServiceData( ParcelUuid(MY_UUID), testData.toByteArray(Charsets.UTF_8) ) } bleAdvertiser.startAdvertising( settings.build(), data.build(), advertiseCallback ) In this way everything works well. Now if testData fields become var testData = "abcdefghijk"

问题 I'm currently trying to use rxandroidble in order to replace the native BLE API of Android of one of our app. How to disable a notification? I'm able to enable it with the sample code, this one: device.establishConnection(context, false) .flatMap(rxBleConnection -> rxBleConnection.setupNotification(characteristicUuid)) .doOnNext(notificationObservable -> { // OK }) .flatMap(notificationObservable -> notificationObservable) .subscribe(bytes -> { // OK }); But in my product I have a use case

问题 In an Android app in central role - how do you please get a hold of the latitude and longitude stored in the org.bluetooth.characteristic.location_and_speed characteristic in the org.bluetooth.service.location_and_navigation service of a BLE peripheral? I am trying the following Java-code - private float mLatitude; private float mLongitude; private static final UUID LOCATION_AND_NAVIGATION = UUID.fromString("00001819-0000-1000-8000-00805f9b34fb"); private static final UUID LOCATION_AND_SPEED

问题 I am trying to read/write these ble characteristics: Right now, I'm trying to read AA01* I am using this library to do it. Here's my code: private void connectToSensorTag(RxBleDevice rxBleDevice) { rxBleDevice.establishConnection(getApplicationContext(), false) .doOnError(new Action1<Throwable>() { @Override public void call(Throwable throwable) { int i = 0; } }) .flatMap(rxBleConnection -> rxBleConnection.readCharacteristic(UUID.fromString("AA01*"))) .subscribe(new Subscriber<byte[]>() {

问题 I have an android app to connect to a BLE device and write to it. I can successfully connect, read and write to it. As a part of testing, we are trying different disconnection scenarions. Sometimes, if ble device disconnect the connection, i get the connection change as disconnect with status value as 19. Also if there is any bond error, status equals 22. If i programmatically disconnect the connection, this status gives me 0. But none of these states except 0 are specified in android

问题 I have a custom piece of hardware with a bluetooth low energy chip. I have set it up with an array with 500 u32s such that array[n] == n. I'm working on an android app that can connect to the device, request the length of the array, and then request the datapoints in the array one at a time. The android app appears to be mostly working fine. It connects to the device, requests the length, and continues to request the next piece of data AFTER the previous piece was received. However, partway

问题 I am trying to connect to AnD UA-651BLE blood pressure monitor and get the values in an android app. The app is able to find the device but I am getting Type_Gatt_Error in 'onConnectionStateChange'. This is working fine for certain devices like samsung galaxy S5, Moto G4 etc. but not for certain phones like redmi 3s prime, etc. This works well and i am able to read data, when i unpair the device and re pair it everytime. I am not able to understand anything as i am new to android-ble
