We are at the tail end of building the first Bluetooth controlled exercise weight machine. We are seeing some interference issues and stability issues. I'm looking for an RF engineer that has experience in the various methods of RF Signal transmission. If you have worked with RC controllers, Bluetooth, or Wifi on embedded systems, I'd like to get your help. It is our goal to build a reliable and fail safe system. Signal integrity and critical mission protocol would be ideal. Please let me know if you are interested.
