Who can Debug this GW Messages?

[siod]

when trying to connect one node with my Gateway I get these messages from my gateway:

0;255;3;0;9;TSP:MSG:READ 21-21-0 s=255,c=3,t=24,pt=1,l=1,sg=0:1
0;255;3;0;9;TSP:MSG:PINGED (ID=21, hops=1)
0;255;3;0;9;!TSP:MSG:SEND 0-0-21-21 s=255,c=3,t=25,pt=1,l=1,sg=0,ft=0,st=fail:1

Can someone explain what this exactly means?
