Connection Refused Android Localhost
only takes a minute: Sign up Android BLUETOOTH connection refused up vote 2 down vote favorite 1 I'm fighting with the craziness of Android 2.3.6 and Bluetooth. From Android bluetooth settings I linked another device. So far, so good. The problem is when I try to connect the device via Android code, I get the error: connection refused Example code

Join them; it only takes a minute: Sign up Android Bluetooth IOException:connection refused up vote 7 down vote favorite 3 Alright here's the deal. I got two Galaxy Nexus phones both with bluetooth enabled. I've written a bluetooth connection management app that I use for device discovery and connectivity. It http://stackoverflow.com/questions/12486695/android-bluetooth-ioexceptionconnection-refused also outputs all the available UUIDs the devices can support. Looking from http://www.bluetooth.org/Technical/AssignedNumbers/service_discovery.htm the following standard UUIDs are exposed from Galaxy Nexus devices. 0x1116 - NAP 0x112f - PBAP (Phonebook Access Profile) 0x111f - HFP (Hands free) 0x1105 - OPP (Object Push Profile) 0x1112 - HSP (Headset Profile) 0x110c - AVRCP 0x110a - A2DP I am trying to connect via the OPP profile (UUID 00001105-0000-1000-8000-00805F9B34FB) and push objects (files) between the devices. I've gone though the entire Android API documentation on how to discover, pair/bond (threading etc.) and manage all bluetooth connections. I've managed to successfully connect and talk to a legacy board device via the SPP (0x1101) profile. However, when I try to use socket.connect() between the two galaxy nexus phones, the pairing dialog shows up and I click Pair button on both devices. After that, I immediately get a Connection Refused IOException. Note that after pairing has occurred once I never get asked again which makes sense since the secure link is cac
Likes Received: 0 I am trying to connect my Droid X2 to my Windows 7/BlueCove Bluetooth server. I previously had my Droid X2 connecting to an ASUS Transformer so I know its possible http://androidforums.com/threads/bluetooth-connection-refused.522154/ to connect my Droid X2 to another system. However, when I try to connect https://www.b4x.com/android/forum/threads/io-exception-error-connection-refused.21111/ to my Windows machine, my Droid X2 sees the machine, but when I try to connect to a service that my laptop is running I get IOException: Connection refused My BlueCove server has been tested using other computers and works fine. Any idea what might be causing this? If it matters I am using: connection refused Code (Text): device.createInsecureRfcommSocketToServiceRecord(SERVICE_UUID); Thanks.

Although, I connection refused android didn't do any pairing or anything before that....do I need to do any special pairing for a secure connection? I thought that was the point. Mar 28, 2012 #3 mcindafizzy Member This Topic's Starter Joined: May 16, 2011 Messages: 6 Likes Received: 0 Ok....after a couple weeks of dealing with this issue I just found a workaround based on another post I found somewhere online: I went and unpaired my windows laptop from my phone and retried an insecure connection. It worked immediately. Now I'm no longer sure what being "paired" means - I never entered any code or asked the system to pair with those devices....yet there they were, all of my computers were shown as being paired devices.... Obviously I cannot ask users to continuously unpair devices to make my app work....does anyone have a clue why pairing/unpairing would have anything to do with the success of a connection? I am very perplexed here. Mar 28, 2012 #4 alostpacket Over Macho Grande?

Erel, Sep 6, 2012 #2 alvinmb Member Licensed User Yes the device was paired prior to connecting to the app I have found a solution if I use : serial1.ConnectInsecure(admin,connectedDevice.MAC,1) it works on the GalaxyS, Galaxy Player and Galaxy Tab. If I use serial1.Connect(connectedDevice.Mac) it only works on the Galaxy S. I don't understand why - however I would like to find out. alvinmb, Sep 6, 2012 #3 Erel Administrator
