I've setup some costumes controlled wirelessly using arduino and XB24 pro s1 w/ RPSMA antennas, point to multipoint, using AT. They work great, but in some instances (for example using them for a convention gig) they don't receive a serial signal. I'm guessing that it's because of a lot of 2.4GHz noise. Is there a better solution, so that there is no loss of transmission? Would the Xbee Pro 900 work in this situation?
I send serial data to five costumes and sync it to music, so transmission is paramount.
