No, in RF24.cpp is the following function, and I patched the last line as shown,
void RF24::begin(void)
{
....
if( setDataRate( RF24_250KBPS ) )
{
p_variant = true ;
}
// Then set the data rate to the slowest (and most reliable) speed supported by all
// hardware.
// MODIFIED - 02/26/13.
// setDataRate( RF24_1MBPS ) ;
setDataRate( RF24_250KBPS );
....
}
Don't ask me what the comment means, I don't know.
