As you can see in the code, the bool write( const void* buf, uint8_t len ); of the radio object handle sending. In the example it's sending the timestamp (line 60 and 112) with size of 4 bytes (long). And when receiving you call radio.read() the same way.

So if you want to send an array, simply put the array pointer in and then the length of the number of bytes, you should be able to send you data array.

The package #X sent/recieved is made by the example, i didn't type it in the code if that works. It's the first example called "Getting started" from the TMRh20 library. I can't paste it on a comment due to its length. Library .ino file

Thanks!

It's what printed out on the log or it's actually the data you sent ? And magically on the receiver side "sent" changed to "received" ? :)

Could you post the code ?

Hi there, I did send very simple messages that said something like "package #X sent" and on the other board "package #X recieved" Thanks.

Hi,

Can you send any byte/data between the 2 boards ?
