Note:

1. The module transmission data rate will affect transmission distance and receiving sensitivity, the higher the data rate , the closer the distance, and the lower the receiving sensitivity.

2. The supply voltage to the module will affect TX power, in the operating supply voltage range, the lower the voltage, the lower the TX power.

3. The module central frequency will change as the operating temperature change, use it under suggest temperature, the module can work well.

4. The antenna will strongly affect the communication distance, please select matched antenna and connect it correctly.

5. The module mount will affect the communication distance.

Operation States

CC1110’s operation states contain: Sleep State, Idle State, Active State,Sleep State is the lowest power mode. After wake up from Sleep State, the module get into Idle State. Except the Sleep State, each state can be switch by SPI interface, also programmed to auto-switch. CC1110’s radio control state diagram is shown as below, for detail information in the CC1110 datasheet.

Data Transmission

The CC1110 contains a 64 byte FIFO for data to be transmitted, built-in hardware support for packet oriented radio protocols, e.g. Preamble bytes, Synchronization Word, Whitening the data, CRC checksum, Interleave and Forward Error Code, Address checksum. The SPI interface is used for sending commend control and writing to the TX FIFO.

The format of the data packet can be configured and consists of the following figure:

In addition, CC1110 supports fixed packet length protocols, variable packet length protocols and infinite packet length. Details refer to the CC1110 datasheet.

Configuration Registers

The configuration of CC1110 can be done with software SmartRF Studio7. Complete descriptions of the registers are given in the CC1110 datasheet. We can provide evaluation board and demo code to the customer to develop and evaluate the module’s capability.

Dimension

Questions and Answers

Description	Reason and Solution
Can’t communication	1.The power supply connect not well, check the module VCC whether it is out of maximum rating. 2.The signal line connect not well, check the module SPI interface. 3.The settings of the transmitter module and receiver module are not the same. Check these modules’ register configuration. 4.Signal block. If the transmitter work with a high TX power, and the receiver was put at a short distance(<0.5m), maybe there is a signal block to make no communication.
Communication distance is too short	1.The application environment is too bad or the antenna is shield. Put the antenna to a better place outside or higher throw a coaxial line , replace it with a higher gain antenna. 2.The work space contains a same frequency interference source, or a strong magnetic field interference, power source disturbance. Try to change the carrier frequency or get far away from the source of the disturbance. 3.The power supply is not strong. Check the voltage and the current whether it is enough.
High data error	1.The power supply ripple is too big, Change the power supply. 2.Check the module register configuration, it is recommended to set as the CC1110-datasheet. 3.There is a carrier frequency interference, change the channel. 4.The antenna unmatched to the module RF interface, change another matched antenna.
