Bluetooth Serial Errors
Hi,
1. I am trying to run an Arduino ROS node connected with a bluetooth serial link. I can get it connected, (with rosrun rosserial_python serial_node.py /dev/rfcomm0) but it won't stay connected for very long. I get the following error (repeatedly):
[ERROR] [WallTime: 1350185780.476810] bad callback: <bound method="" subscriber.callback="" of="" <rosserial_python.serialclient.subscriber="" instance="" at="" 0xa2b65cc="">> Traceback (most recent call last): File "/opt/ros/electric/stacks/ros_comm/clients/rospy/src/rospy/topics.py", line 581, in _invoke_callback cb(msg) File "/opt/ros/electric/stacks/rosserial/rosserial_python/src/rosserial_python/SerialClient.py", line 121, in callback self.parent.send(self.id, data_buffer.getvalue()) File "/opt/ros/electric/stacks/rosserial/rosserial_python/src/rosserial_python/SerialClient.py", line 473, in send self.port.write(data) File "/usr/lib/python2.7/dist-packages/serial/serialposix.py", line 485, in write raise SerialException('write failed: %s' % (v,)) SerialException: write failed: [Errno 5] Input/output error
Has anyone seen this before and knows what to do about it?
2. Also, does any one know what this error means? I get it as I run my program, but I can receive messages from my Arduino regardless of if its showing...
[INFO] [WallTime: 1350185758.107044] Packet Failed : Failed to read msg data
