I have a project that requires a main controller and slave controller type of topology. I also need to be able to send commands to each slave individually. Ideally it would need to be wireless as well.
I know I could use Xbee and have a mesh, but how would I send commands to just a single slave controller?
I’m open to other suggestions of wireless technology but would also like to keep the overall cost of the slave units down. The distance will only be up to 10 meters at most. I would think the maximum number of slave controllers wouldn’t exceed 15 either, but would like to future proof it as well.
Thanks in advance!
