Hello, I've been trying out the Xbee network tutorial from the wiki:

My setup: Raspberry Pi with Xbee Series 1 and Arduino Uno with Wireless SD shield that has a Xbee Series 1 on top of that.

I have configured the Xbee's with XCTU and the xbee is connected to the AMA0 port

When I try to run the command: rosrun rosserial_xbee /dev/ttyAMA0 1 I can see the Arduino flashing as if it is sending the data. When i open Arduino's port monitor i can also see that it is sending the data. So i guess the Xbee connection isn't the problem here?

I get the following error:

Traceback (most recent call last): 
File "/usr/lib/python2.7/", line 552, in __bootstrap_inner
File "/usr/lib/python2.7/", line 505, in run 
   self.__target(*self.__args, **self.__kwargs)
File "/home/pi/catkin_ws/src/rosserial/rosserial_python/src/rosserial_python/", line 434, in run 
   if self.port.inWaiting() < 1:
AttributeError: FakeSerial instance has no attribute 'inWaiting'

I found only one other person struggling with the same problem here; But no obvious fix was found? The marked answer suggests that installing ROS hydro rosserial fixes the problem. Can that actually work?

I found a temporary solution for my problem! I tested different versions/tags (whichever is the right terminology) of the Rosserial git and I found out that the problem was introduced in version/tag 0.5.6. So for now I guess I will use 0.5.5, which works nicely with the xbee.

EDIT: It turns out I came across a lucky bug, because when I tried to do the same again on my other ROS copy, it did not work. Really hope this issue gets fixed soon!

hi, could you please describe the steps in detail to downgrade the rosserial version. That should work because on the answer posted the author said: "The bug would have been introduced in 370f579".

To downgrade rosserial, you need to first go into your rosserial git directory and enter: git checkout CommitCode. For example: git checkout ba83ced96c

After that, you can just go back to your workspace dir and enter the usual commands: catkin_make and after that catkin_make install

Oh and you can get the commit codes from the rossserial github site:

git checkout ba83ced96c is for example rosserial 0.5.5

The correct fix should be to add an inWaiting method to Just like the author said. But I don't have enough knowledge on how that script works or what the method should contain.

I know I look into it also, but it's not an option for me at the moment. Have to deliver my project soon lol. I'll look at it afterwards. @rip24 when you say "go into your rosserial git directory" do you mean /opt/ros/indingo/share/rosserial??

By the git directory, i mean the location where you downloaded the rosserial git with the command git clone . git clone downloads the ENTIRE library, so all the versions are already in there, you just need to tell it to install some other version.

My dir for example: ~/catkin_ws/src/rosserial
