High latency with raspberry
Hi,
I have a raspberry connected to a kobuki base and a lidar, I connect to it by ssh to run all my nodes. It has always been running fine but since this week there is a high latency between my computer and the raspberry. For example, when I try to run only the lidar node it starts spinning after 5 seconds when it took no time before. Same for the kobuki that can take for more than 2 minutes (!) to start.
I've always been using my computer as the master (so ROS_MASTER_URI is correctly set on my PC and rasp to the IP adress of my PC).
I'm a little bit confused about this and I thought it could be a clock synchronization issue but if I run the roscore on the raspberry there isn't any latency. It's only happenning when roscore is running on my PC, if I use another computer I don't have latency.
I also thought it could be a network issue but pinging the raspberry didn't reveal any problem.
Do you know what could be the issue ?
Delib, was wondering if the problem has been resolved. Also, if you also notice the control dead time gives large latency as shown in here: https://github.com/yujinrobot/kobuki/...
