Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Start the server with roscore running on the phone
2. Connect the client to the server.
3. Click images and try to get data by connecting to the server from another 
laptop..

What do you see?
Server goes unresponsive and the client disconnects as soon as an attempt is 
made to retrive the images. Not able to reconnect the client after.

In log 2, the pictures filled up the SD card:

Exception in photoCallback\

java.io.FileNotFoundException: /mnt/sdcard/20110821_032100.jpg (No space left

We need to check for an exception when we do the file saving, I think.

In log 1, some sort of weird hostname is being used:

Failed to invoke method registerPublisher in class 
org.ros.internal.node.xmlrpc.MasterImpl: java.net.UnknownHostException: bull\
E/XmlRpcErrorLogger( 8514): org.apache.xmlrpc.common.XmlRpcInvocationException:

E/XmlRpcErrorLogger( 8514): Caused by: java.lang.RuntimeException: 
java.net.UnknownHostException: bull\

Was some computer named "bull" broadcasting an invalid URL to itself?

bull is set to 127.0.0.1 so that shouldnt be an issue

The problem is that while bull is set to 127.0.0.1 on Balajee's machine, that 
doesn't really mean much to the DNS lookup on the android phone.

Closing this as _wontfix_ because it applies to pre-UDP infrastructure.
