I want to send information from arduino e-health sensors to 3 arduino uno boards with xbee S2 module, now i can send information from coordinator(arduino uno) to router/end device(this is a router/end device), but when i connect the third xbee module its not receive data. I thing i must replace the coordinator and the router/end device....(coordinator-e health, and the router/end device to arduino uno with led diod)
