ORBIT-USER: changing wireless channel.

[Andrea G Forte]

Dear all,

every time I try to change the wireless channel of a node in master 
mode, I get the following error:
ERROR CONFIGURE_ERROR: Couldn't configure 'net/w0/channel' on 'n_1_10':

The part of relevant code I use is:
node.prototype("test:proto:receiver" , {
    'protocol' => 'udp'
  })
node.net.w0.channel = 1

Your help is as always very much appreciated.
