Hi All
I'm trying to setup a XBEE RF link between an Uno and a Pi-4. Uno has a HC-SR04 to detect presence of an object....once verified....data sent via XBEE RF to a Pi- Controller. The Pi then will take a photo using embedded Camera......using Tensor Flow Lite....to determine if the detected object matches a Tensor-Flow model....then XBEE responds back to the Uno to drive Outputs based on the result.
My Issue is has anyone setup a Duplex XBEE RF link between an Arduino Uno + a Pi-4? If they have .....would really appreciate sharing how this is configured?

You ask about full duplex, then describe half-duplex communication.

Being fair to the original party, he does not ask about full or half duplex just duplex.
I admit I thought exactly the same until I reread his post twice more.
I took that from the title of his thread. In all cases I ever encountered, full duplex was not necessary or even possible. One case where a customer changed from half-duplex modems between two IBM mainframe computers, to fully capable full duplex modems, it killed their communications because the computer lost the beginning message data as they were still sending the end of the last transmission. Had to implement RTS/CTS pins on the modems to fix the timing.
