@jim-p thank you for your suggestions, I lowered the speed from 2M to 250k with the same MAX power and it has improved a lot, the transmission is almsost without delay, some few moments where the transmission is cut off for a very short moment. I put an LED to monitor whether the signal is cut off.
if (myRadio.available())
{
myRadio.read(&dataReceive, sizeof(data
Receive));
digitalWrite(ledSignal, HIGH);
}
else
{
signalTest++;
if (signalTest >= 110)
{
digitalWrite( ledSignal, LOW);
if ( signalTest == 111)
{
signalTest = 0;
}
}
}
ledSignal is ON as long as there's data received by the RX, and it's off when the transmission is cut off.
