Re: [Paparazzi-devel] No serial communication between PC & XBee?

[Bernard Davison]

Thanks Alston,

The doc was a good read though I think that the wiki now contains a  
little more data though I must say that some of your wordings were a  
little less confusing so I'll take a look at updating the wiki.

I got a couple more XBee-PRO modules today and once I configured one  
as a coordinator and tried to connect to the plane everything worked  
as it should have. :-)
I'm now up and away which is great.

The question is now... what exactly can I update the wiki with so that  
others who find themselves in a similar situation can learn from.
Will have to put my thinking cap on.

Thanks all,

Cheers,
Bernie.
