With a PA+LNA module (+7dBm TX, LNA gain): Script RF24- alcance de arranque- alcance de GK...

| Strategy | Implementation in script | Range gain | |----------|-------------------------|-------------| | Dynamic payload reduction | Use enableDynamicPayloads() + send only essential data | +15% | | Forward Error Correction (FEC) | Send each byte twice and majority vote | +20% (but halved throughput) | | ACK with payload | Use writeAckPayload() to confirm and send data simultaneously | +10% | | Channel hopping | Change channel every 50ms to avoid interference | +25% in noisy environments | | Low-power listening | Gateways listens for 99% of time, device transmits short bursts | +30% range (due to lower noise floor) | Using a standard nRF24L01+ PCB antenna:

| Symptom | Likely cause | Fix | |---------|--------------|-----| | No startup connection | Low voltage / bad capacitors | Add 100 µF electrolytic + 0.1 µF ceramic | | GK mode unstable | Insufficient current | Use separate 3.3V regulator (500 mA+) | | Short range even at PA MAX | Wrong antenna / missing uFL connector | Check antenna type (PCB vs external) | | Interference | WiFi on same channel | Set channel < 20 or > 80 | With a PA+LNA module (+7dBm TX, LNA gain):

The RF24 library abstracts the complex SPI communication of the nRF24L01+. It allows Arduino, ESP32, Raspberry Pi, and Linux-based systems to send data with configurable:
