= Troubleshooting =
No communication:
- Verify transmitter voltage (1.8V to 3.6V) and receiver voltage (3.3V to 5.5V)
- Check antenna length and orientation
- Avoid large metal objects near the modules
Short range:
- Use longer antenna wire (17.3cm for 433MHz)
- Check for signal interference
- Verify data rate matches receiver mode settings
