RF24Network - How set speed to 250KBPS?

Using Arduino Programming Questions

Hello to all!

I'm trying to use the RF24Network library.
First I've played with the RF24 library and tested the simple pingpair example.
I've used the 'radio.setDataRate(RF24_250KBPS);' to reduce speed and increase the range.

Now I would like to do the same with the meshping example but cannot change the speed.

I've set it up here:

(...)
void setup(void)
{
  //
  // Print preamble
  //
  
  Serial.begin(57600);
  printf_begin();
  printf_P(PSTR("\n\rRF24Network/examples/meshping/\n\r"));
  printf_P(PSTR("VERSION: %s\n\r"),program_version);
  
  //
  // Pull node address out of eeprom 
  //

  // Which node are we?
  this_node = nodeconfig_read();

  //
  // Bring up the RF network
  //

  SPI.begin();
  radio.begin();
  
  radio.setDataRate(RF24_250KBPS);                         ######<---------------------------
  
  network.begin(/*channel*/ 100, /*node address*/ this_node );
}
(...)

But I obtain:

Model            = nRF24L01+
CRC Length       = 16 bits
PA Power         = PA_HIGH

Do I use the command in the wrong place? It's the wrong command for the RF24Network version?

Thank's for the help!

Sorry byt, noone has experience with this library? :slight_smile:

Thank's!

It's been a few years, but since I just ran into this problem and this was one of the top Google results...

If you're using the TMRh20 version of the RF24Network library, you can see in the source code that network.begin() seems to overwrite the radio settings. You'll need to move your radio.setDataRate after the network.begin() and you should be back in business.
