failed to fill bcap buffer

[Booooooosh]

So I've been successfully connecting to the DENSO VS6577 for a few times. But during one of the execution, the program failed and the roscore is aborted, and after that, there is a ERROR saying that 'failed to fill bcap buffer' whenever I tried to reconnect to the robot. Is there something wrong with the BCAP layer?

Here is the output:

[FATAL] [1512072501.667538111]: failed to fill bcap buffer
[ERROR] [1512072501.667599961]: failed to initialize denso robot

Update 1

So I was able to reconnect after I shutdown the robot for a while and restart my PC. I guess it has something to do with the network communication?

Many thanks!
