This is a bit of a follow on from my last question about PIC communication...
I've got a (potentially unlimited) number of devices that need to talk to each other in a multi master setup, they could be up to 10 metres or more apart. I was planning on linking them with wires but am starting to wonder if some sort of wireless communication would be easier to implement and be more practical.
Now comes the problem, I've got no experience at all with wireless comms so am appealing to the great minds on here for a nudge in the right direction. What are my options? I've seen, bluetooth and ethernet transceivers that might to the job, there's microchips MiWi or just a straight RF Tx\Rx pair.
The only real requirements is that I want it to be as low cost as possible, I'll be sending small packets (currently only 3 bytes but that'll grow when I add in error checking, parity, start\stop signals, so say 10 bytes tops) and data transfer speeds doesn't need to be particularly quick. I've ordered a bunch of cheap RF modules from China to play with but would love to hear other peoples thoughts on my options. Any pros and cons, any gotchas that I need to look out for?
Thanks in advance guys
