My setup is like this:
I have one master arduino, that will transmit broadcast message to all the slave arduinos. This part i have managed to do as i connected my master TX to the slaves RX. But how can i send info collected from the slaves to the master?
The problem it seems to be that when I transmit from one slave TX my message will not arrive to the master's RX pin.
How can i resolve this problem?
I don't want to use I2C connection, because all the slaves will have I2C devices attached and i dont think they can be slave for one device and master for other.
