Sending data both ways, how to use Half Duplex

[embeddedDevEnthusisast]

Hello! I have been using this library for a while for my embedded systems projects. I am wondering how to use Half-Duplex data communication with this library, that is sending data both ways but at different times between two transciever modules.

Thanks

So, technically it is pretty simple. You have to call in the two modules this function in the void loop:if (Serial2.available()) {. if you need to send something just make the Arduino some stuff and then use the command:Transceiver.SendStruct(&MyData, sizeof(MyData)); Here's an example: void loop() { if (Serial2.available()) { Transceiver.GetStruct(&MyData, sizeof(MyData)); Serial.print("aperto: "); Serial.println(MyData.aperto); if (MyData.aperto) { passwordGen(5); Transceiver.SendStruct(&MyData, sizeof(MyData)); } } }

I thought I responded--I do this all the time

Have all devices in "listen mode" meaning in a loop keep looking for incoming data, in that loop, send when needed, since others are always listening, they will get the message

something like this....

loop(){

// measure data if (enoughdata){ // build struct needToSend = true; }

If (needToSend){ needToSend = false; // send data as shown in examples } delay(50); // give time for EBYTE to do it's thing

if (EBYTESeria.available()) { // read data as shown in examples // process received data // this could also be a function to process data and send right back out (see measure data section) }
