I guess the question is whats the best way to have 2 way communication wirelessly? I bought 2 rx/tx modules (different frequencies)from sparkfun.com and was trying to use them to communicate 2 ways. The attached jpg is one of the 2 boards. The other board is identical except the Rx and Tx frequencies are opposite.
Basically I wanted one board in my car and another outside of it attached to my transmission. I first wanted one board to send a signal which the other would receive and retransmit back to the original one to turn an led on to indicate they were linked. I just tried to get this to work on a bread board and it worked for a few minutes but was really really slow. It wont do it anymore but Im going to bed and will look at it tommorow. Is there a better way for me to do this? Wireless isnt neccesary for my transmission project but would make it a lot easier to install/remove and of course the cool factor
I really need 4 byte communication both ways (or more ) so if you guys have a better Idea, let me know. Im not even sure it would work through the body of the car but I havent gotten that far to test it yet. Thanks for the help
