Half-Duplex Communication

Discussions center on half-duplex versus full-duplex communication methods, including transmit/receive switching, in-band signaling, multiplexing, and protocols like CAN in constrained hardware or wireless environments.

Transmit with anus receive with eyes, full duplex!

Wouldn't infrared be acceptable for data transmission?

If they're not communicating, how are they sending back lots of data?

The eternal struggle with in-band signalling...

Didn't know that! Do they switch between transmitting and receiving constantly to keep up a 2-way data stream?

I like this. It sort of simulates requiring a wired connection for communication.

It's like dual porting but twin half duplex!

It's up there with the accepted Tx/Rx for transmit and receive.

what is your suggestion for duplex communication?

fnord77 • May 20, 2021 • View on HN

communication through them should be possible, though, no?
