    <p>I have a strange issue that I can't seem to figure out what's going on. I am using the Bluetooth chat example as a base and things work fine for the most part, however, when trying to swtich connections from one UUID to another (two different apps). The hardware closes the connection and opens a new one with the different UUID. </p> <p>The problem is that my bluetooth socket isn't getting closed on the app side. I see these messages in the log:</p> <pre><code>11-20 15:00:44.287: I/BTL_IFC(13313): btl_ifc_ctrl_rx: [BTL_IFC CTRL] recv BTLIF_BTS_RFC_DISC_IND (BTS) 11 pbytes (hdl 47) 11-20 15:00:44.287: I/BLZ20_WRAPPER(13313): btlif_ctrl_callback: btlif_ctrl_callback : msg id BTLIF_BTS_RFC_DISC_IND 11-20 15:00:44.287: I/BLZ20_WRAPPER(13313): btlif_process_disc_ind: disconnect ind status 19, rc chan 8 11-20 15:00:44.287: D/BLZ20_WRAPPER(13313): btlif_signal_event: fd (-1:51), bta 5, rc 8, wflags 0x0, cflags 0x6, port 9053 11-20 15:00:44.287: D/BLZ20_WRAPPER(13313): btlif_signal_event: ### event BTLIF_BTS_RFC_DISC_IND not matched ### 11-20 15:00:44.287: I/BTL_IFC(13313): send_ctrl_msg: [BTL_IFC CTRL] send BTLIF_BTS_RFC_DISC_IND_ACK (BTS) 9 pbytes (hdl 47) </code></pre> <p>So I know it's being disconected, however my socket remains open. I would assume when I try to do this it would give me anI/O exception, but it doesnt.</p> <pre><code>mmInStream.available() </code></pre> <p>It just returns 0 and keeps going. I also monitored the mClosed flag in the BluetoothSocket.java class and it never gets set to true in this case.</p> <p>I'm registered for the the normal dissconnect intents, am I missing one?</p> <pre><code> IntentFilter stateChangeFilter = new IntentFilter("android.bluetooth.adapter.action.STATE_CHANGED"); IntentFilter disconnectFilter1 = new IntentFilter("android.bluetooth.device.action.ACL_DISCONNECTED"); IntentFilter disconnectFilter2 = new IntentFilter("android.bluetooth.device.action.ACL_DISCONNECT_REQUESTED"); registerReceiver(mListenForDisconnect,stateChangeFilter ); registerReceiver(mListenForDisconnect,disconnectFilter1 ); registerReceiver(mListenForDisconnect,disconnectFilter2 ); </code></pre>

    1. COThe only thing that can cause it to crash is if I try to do `mmOutStream.write(byte)` but I don't want to just write bytes out constantly to see if there's still a connection.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
