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.
Can't
3 ． The settings of the transmitter module and receiver module are not the same. Check these
communication
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.
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.
Communication
2 ． The work space contains a same frequency interference source, or a strong magnetic field
distance is too
interference, power source disturbance. Try to change the carrier frequency or get far away from
short
the source of the disturbance.
3．The power supply is not strong. Check the voltage and the current whether it is enough.
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 CC1121-datasheet.
High data error
3．There is a carrier frequency interference, change the channel.
4．The antenna unmatched to the module RF interface, change another matched antenna.
