android-bluetooth

I have two different bluetooth apps. The first provides a service and listens to commands from the other commander app. I have a GT-I9100T phone and a GT-P5210 tablet. The tablet when acting at the listener works fine and the phone can see the UUID for my app. But when I run the phone as the listener, the UUID of the listener is not listed. I filter the devices by my application UUID so that I know I am talking only to those devices with my application running. My listening app looks like this (I get the same result if I use an insecure connection as well): private final UUID GUID = UUID

I'm trying to have my app's service listen for Bluetooth connection and disconnection attempts, so I can dynamically check/support Bluetooth tethering network communication. First I have two Samsung S4s (running CyanogenMod 10.2, which is Android 4.3.1 based) which I can pair just fine. If I set one device to Bluetooth tether, when the other connects, a new bt-pan network interface is created and DHCP is used to assign IPs. I confirmed this using iwconfig and ifconfig in shell. I have the following perms in my app: (there's more, I'm just pointing out the BT perms I added) <uses-permission

I would appreciate an example of BLE peripheral mode for Android-L. The code that I have gives me strange errors (i.e too many advertisers) which makes no sense as there are no advertisers that i can see from scanner like Lightblue on ios. https://github.com/geoaxis/BluetoothTest works on my nexus 5 running L. At first when initializing advertising I was getting: public static final int ADVERTISE_FAILED

I am working on BLE Applications, I have tested with different devices like Nexus, Moto, Samsung, LG. I am getting the GATT Error 133 in Samsung Devices alone(Samsung A5 2016). Trying to connect 10 times it gets connected only 2 or 3 times.Please Help me out. 来源： https://stackoverflow.com/questions/40465373/android-ble-gatt-error-133-getting-often-with-samsung-devices

I need to turn on Bluetooth in an android device programmatically and wait till it on to proceed to next line of code. My code is as below if (!mBluetoothAdapter.isEnabled()) { Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE); ctx.startActivity(enableBtIntent); } When doing like this, the code continue to execute from nect line without waiting for bluetooth completely on. Is there any way to solve this? Can I add a look to check if bluetooth is on? You can register a BroadcastReceiver to listen for state changes on the BluetoothAdapter. First create a

We are developping a custom bluetooth low energy peripheral and we need to define our custom service. Based on this link: https://www.bluetooth.org/en-us/specification/assigned-numbers/service-discovery All short UUID (16 bits) are reserved pending future revisions of the BT services specs. And it seems that current version of Android (4.4) doesn't support the 128 bits UUID. So basically i can't use a 16 bits UUID for defining my service, but i can't filter my services with Android for a 128 bits UUID. Anyone got an idea on the best way to implement it ? Thanks M to the K I'm still not sure if
