They're definitely duplex, rather than simplex - but whether they're full or half duplex I don't know ... I haven't had need to pass data simultaneously in both directions.Do the units work as simplex or have they got to be used half duplex?

Yes you can do that. The only real difference is that the HC-12 parcels-up the data into packets - so the gaps between the characters will be different. Also the HC-12 presumably has a finite buffer size (and there's no flow-control), so there would come a point where you have to stop sending data, and wait for the HC-12 to deal with it. (I seem to recall that this varies with the mode the HC-12 is in).him as well said:Don't suppose its possible to simulate any of this?, can two picaxe communicate serially hardwired, the info seems to imply that the HC-12 just replaces a serial link?
