I have a small question about Broadcaster/Observer pair. I know that Broadcaster/Observer implement unidirectional communication.
My question is "It is possible to receive acknowledge information from observer to broadcaster?"
I have two devices (sensor as broadcaster and receiver as observer), and I want to transmit some data (e.q temperature data) from sensor to receiver . And I want to know that the observer (receiver ) has received the information from the sensor (broadcaster), something like acknowledge.
