Instructions for Use:

1. Power Supply Setup:

   • Ensure the supply voltage is within the specified range of 1.8 to 3.6 V.
   • Use a stable power source to avoid fluctuations that can affect performance.

2. Configuration:

   • Configure the CC1140 using SPI interface for setting up frequency, data rate, and other parameters.
   • Use the provided register map in the datasheet for detailed configuration settings.

3. Transmit Mode:

   • Set the desired transmit power level within the -30 to +10 dBm range.
   • Load the data into the FIFO before transitioning to transmit mode.

4. Receive Mode:

   • Tune the receiver to the correct frequency band.
   • Enable automatic packet handling for address filtering and CRC checking.

5. Low-Power Operation:

   • Utilize the wake-up timer for low-power applications to minimize power consumption.
   • Switch to sleep mode when not actively transmitting or receiving data.

6. Antenna Connection:

   • Connect an appropriate antenna tuned to the selected frequency band for optimal performance.
   • Ensure proper impedance matching to maximize signal strength.

7. Testing and Debugging:

   • Monitor the RSSI (Received Signal Strength Indicator) for assessing signal quality.
   • Use diagnostic tools to check for errors in packet transmission and reception.
