[ros-users] [Discourse.ros.org] [TurtleBot] [TB3] problem to connect wiimote to Turtlebot 3

[Kening Ren]

I have two issues:
Issue#1:
In Teleoperation chapter:  http://turtlebot3.readthedocs.io/en/latest/teleoperation.html, for every listed remote controller, all operations are marked as "[Remote PC]". Should it be "[Turtlebot]" instead? We need to connect the remote controller directly with TB3, in order to control TB3 via the remote controller. It has nothing to do with the "Remote PC". Please clarify this. 

Issue#2:
I am not able to connect wiimote to TB3.
Here is what I did:
At first, run:
sudo apt-get install ros-kinetic-wiimote
then:
rosdep install wiimote
then:
rosmake wiimote

Everything is fine. No error found.

Then I try to pair wiimote with TB3. I get the following error:

$ rosrun wiimote wiimote_node.py
Press buttons 1 and 2 together to pair (within 6 seconds.)
    (If no blinking lights, press power button for ~3 seconds.)
Wiimote read error
Read error (nunchuk cal)
/opt/ros/kinetic/lib/python2.7/dist-packages/wiimote/wiistate.py:157: RuntimeWarning: divide by zero encountered in divide
  self.acc = WIIReading((self.accRaw - self._accCalibrationZero) / (self._accCalibrationOne - self.accCalibrationZero), self.time)

Then I added some logs in wiimote_node.py. and I found that the following line is not working:

wiimoteDevice = wiimode.WIIMote.WIIMote()

I went through the source code of wiimote module: WIIMote.py and then found that the following line is causing the problem:
self._wm = cwiid.Wiimote()
See http://docs.ros.org/diamondback/api/wiimote/html/WIIMote_8py_source.html

Anyway, I am able to pair wiimote directly with Ubuntu. But I am not able to pair it with TB3. 
Have you seen similar problem? Any solutions?

Thank you very much.
