knxlib.ping over KNX IP

[savaskorkmaz]

Hi,

In one of our project , knxlib.ping is working over KNX TP but it's not working over KNX IP. 
Do we need to use another command or should we do something in LM settings ?
Or do you suggest to change something in KNX IP Router ?
Or it's just not working over KNX IP ?

Regards
