Connection ok but no comunication

[MrVince]

Hi everyone :)

I've build a relay to control my Senseo. All seems ok, I power the arduino/relay with a 5V transfo from USB charger, all seems ok, my arduino was add by the GW, but i can't send order to it.

See below my log

Oh, and when I send a request, I see that :

Thanks for your help, and happy new year :)

Can you please post your code?

[gohan]

In the node log, do you see the " Incoming change for sensor:" message?

[MrVince]

Oh, when I plug a nano on computer with USB the GW connect without problem

[gohan]

Did you try different power supplies? Did you put capacitor near the radio module?

[MrVince]

I try 2 power supplies, and I put the radio far away from it.

And I use a decoupling capacitor like says in "Connecting the radio" page

I don't understand what happend wrong with the log, can you explain me? Thank's

[gohan]

You need to debug the node, not the gateway, look in node's log.
