Hello all,

I would like to know if its possible to use random data in the  
gr-ieee802-11 module. Currently, a message strobe feeds “Hello World!”  
into  
the module. Any feedback will be appreciated.

Thanks  
kc

Hi Kelvin,

to me, “Hello World!” feels pretty random 😉

Yes, you can do that. You can, for example, use a random source to  
generate random bytes, and feed that sample stream into a message sink  
(maybe after building vectors out of these bytes). Using a throttle  
block, you could limit the rate at which random bytes are generated.

Greetings,
