Controller with NodeJS

[Fl0rian]

Hi,

I want to work with NodeJsController.js file.
Can you help me, and give me responses of :

• What is the role of "loadFirmware" method ?
• Why "saveProtocol" method is called only if sensor = 255 ?
• When I connect a new node relay, I can see this :

send: 105-105-0-0 s=255,c=0,t=18,pt=0,l=5,sg=0,st=ok:1.5.1
send: 105-105-0-0 s=255,c=3,t=6,pt=1,l=1,sg=0,st=ok:0
read: 0-0-105 s=255,c=3,t=6,pt=0,l=1,sg=0:M
repeater started, id=105, parent=0, distance=1
send: 105-105-0-0 s=255,c=3,t=11,pt=0,l=5,sg=0,st=ok:Relay
send: 105-105-0-0 s=255,c=3,t=12,pt=0,l=3,sg=0,st=ok:1.0
send: 105-105-0-0 s=1,c=0,t=3,pt=0,l=0,sg=0,st=ok:

I don't understand good these steps.
Why the node send all information with "s=255" and send the latest with "s=1" ? In the controller, I must save only the latest version, so "s=1" ?
Actually, the "saveSensor" is called 2 times :

send: 105-105-0-0 s=255,c=0,t=18,pt=0,l=5,sg=0,st=ok:1.5.1
send: 105-105-0-0 s=1,c=0,t=3,pt=0,l=0,sg=0,st=ok:

Thanks for your help.
