Topic: How do I compare the received data from a nRF24L01 module? (Read 60 times) previous topic - next topic


I can PRINT the received data, but I can't compare them with something else.

I use RF24 library.

On transmitter side I send the array of chars char text[] = "porta"; like this:

Code: [Select]
void porta_function() {
  char text[] = "porta";
  radio.write(&text, sizeof(text)); }

On receiver side I receive and print this array with no problem:

Code: [Select]
void loop() {
  while(radio.available()) {
    char text[32] = "";
    radio.read(&text, sizeof(text));
    Serial.println(text); }

But when I add in the loop this:
if(text == "led") {

the whole loop stops working although it compiles. I don't even get the print of Serial.println(text)

What is my mistake?
