Selecting a wireless module

Wireless & IoT
1

I’m planning to integrate some wireless communications between two of my robots. However, I have no experience or knowledge in wireless stuff. Basically, I just want to send some data from one ATMega32 to another ATMega32, which are always at the most 3 metres apart.

I don’t know which modules are suitable for my use. How do I communicate with the modules? Also, If I get two transmitters and two recievers with the same frequency, will I have to get some sort of channel thingy going on to distinguish between the two transmitters and recievers? Would it be better to get a transciever?

for simplicity

consider

http://maxstream.net/products/ $20@1ea module. Transparent serial port extension via RF. Each radio has a MAC address. Or you can run ZigBee routing.

Similar, from

or the Jennic modules on this website.

also Bluesmirf or another bluetooth setup would be great, there’s some cool bluetooth serial modems in the SFE product listing which I highly recommend.
