nrf24l01 receiving trash

Projects Networking, Protocols, and Devices
1

These are my first steps with the nrf24l01. I have tried to establish a connection between two chips,
but I did not succeed. Even if there was no transmitting chip these lines caused my serial monitor to overflow.

if (radio.available())
{
char text[32] = "";
radio.read(&text,sizeof(text));
Serial.println(text);
}

It had mostly empty lines in it but sometimes something like this:

}o?????'aaa
~N?????

I tried to change the channel and the pipe and even turned off my wifi but it didn't change anything.

I don't know what to do.. please help!

Maybe

radio.read(text,sizeof(text));

The subtitle of this forum is "For problems with Arduino itself, NOT your project" (emphasis added) so why do you post it here? I will ask a moderator to move it to a more appropriate section.

Check your wiring.

Have a look at this Simple nRF24L01+ Tutorial.

The examples are as simple as I could make them and they have worked for other Forum members. If you get stuck it will be easier to help with code that I am familiar with. Start by getting the first example to work
