pairing

android noob here! Is there a difference between when two android devices (smartphones) are 'paired' and when they're 'connected'? If so, what is the difference when transferring data from one to the other? mariopce Please imagine yourself in such a situation: You come to car with BT audio system first time. You are not paired and not connected. You pair the devices and because you are close to the car you immediately connecting. But when you go to home and you are away from car you are disconnected but paired. When you come close to the car again, you don't need pair, you don't need put pin

I've been searching the internet and haven't seen anything in the way of how to exactly implement OOB pairing. I was hoping somebody here could point me to some example code to help me out. The chat example in the Android developers site didn't really dive into this type of pairing at all. Basically, I have an Android tablet that I want to securely pair with a device, written in C++, that has no built in display/IO mechanism. The tablet to be paired will act as the GUI/IO interface and I'll send message back and fourth over Bluetooth. Thus I want to securely pair the tablet with each device

I am having trouble connecting two Android devices via Bluetooth, which happens only when they have been paired before. I am running one as the server and the other as the client. Here is the sequence of things on the server side: Check various Bluetooth statuses (adapter available, is enabled, etc). call listenUsingRfcommWithServiceRecord() with a pre-defined UUID that I chose. request to make device discoverable since being discoverable happens asynchronously, I call accept() and wait for an incoming connection. On the client side: Check various Bluetooth statuses (adapter available, is

I implemented a GATT Server and Client App on Android. The connection is working and I forced pairing by adding PERMISSION_READ/WRITE_ENCRYPTED_MITM to all of the GattCharacteristics. But the pairing behavior differs on different clients: 1) Pin is shown on the client/central (Android 5 on Samsung Galaxy S3) and should be insert on the server/peripheral (Android 7 on Nexus 5). 2) Passkey is shown on both devices client/central (Android 5 on Samsung Galaxy S3) and server/peripheral (Android 6 on Nexus 7) 3) Pairing with Windows or iOS fails with server/peripheral expecing a pin for input. What

Recently I tried to get a pairing process to work programatically and I succeded. But I recently found out that the users of my application can be connected to several of "interesting" devices. So I have to prompt the user to choose a device to connect to So I have to connect the user to a already paired bluetooth device. But none of my efforts work. I tried running the pairing process again using the: tmp = device.createRfcommSocketToServiceRecord(MY_UUID); and also the following: Method m = mmDevice.getClass().getMethod("createRfcommSocket", new Class[] {int.class}); mmSocket =

I'm a beginner in Android programming since I only started 3 months ago. I'm doing a project which connects the android app to arduino using bluetooth. I already have a code for the android app (bluetooth.adapter,sockets,.etc.). The code for connection is already working. One of the goal is for the android app to automatically input the password when pairing with the bluetooth device without asking user to input the PIN. The old posts on this forum do not help much. (many suggested using insecure mode, but I do need secure mode, also in my case, the arduino is the server while cellphone app is

In the Android 2.3.3 BluetoothChat example with with createInsecureRfcommSocketToServiceRecord() API, users are still prompted to accept the pairing request, even though no PIN code is presented. Is there a way to automate Bluetooth pairing request without user intervention? Or is this never possible due to security concerns? I have been looking online for 2 days now and haven't really found much, so if anybody knows, please post. Thanks! Not with the standard API, no: if the MAC address is not already in the pairing database there will always be the prompt. I'm told that if you have a device
