I am currently using the NRF24l01+ but i want to know if I should be using a different product for my application.
I am sending very small amount of information (such as hex color codes) from one device to another. I want to have a stable connection in noisy environments like tradeshows, but I think I may be getting a lot of interference in from other people connecting to wifi and using bluetooth nearby.
I want to know if there is a different product that would be recommended to avoid interference and preferably with a longer range. Should I be looking at sub 1ghz?
Also it needs to be legal for use in Japan.
Any help is greatly appreciated!
