Re: [Paparazzi-devel] Wireless link

[Gareth Roberts]

Hi Marcio,

Welcome to the mailing list!
I'm using a similar setup to communicate with a small linux SBC.  It's a complete pain which I would avoid if I had any other possible option.  AD-HOC networks are shaky and the range is nothing compared to the XBee's. 
The nice thing about XBees, which I appreciate more and more working with AD-HOC is that once they are set up properly, you plug them in and they just work. 
Unless you desperately need to trade range for bandwidth (which, if you are using it with a standard paparazzi, you won't) I would seriously recommend against it.
A pair of XBee's will cost you about £70 from here:

Your module would be cheaper, but you'll have to sign a fairly horrible looking NDA before buying one, which will mean you can't legally tell anyone else any information about the module (so we won't be able to answer questions about it).  I'm not sure whether the module will operate under Linux properly either.

Others may disagree, but if you're new to the system and autopilots in general, the less weird stuff you have to deal with the better - it can be tricky enough getting everything working if it's standard!

Good luck!

Hi all,

    A newbie question:

Can I use a low cost wi-fi module for wireless link on paparazzi ?

The ground station laptop connects to wi-fi module using AD-HOC.

Course I also need a microcontroller to control the wi-fi module

but it´s easy to do.Thanks.
