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 CC2500-datasheet.
3
．
There is a carrier frequency interference, change the channel.
4
．
The antenna unmatched to the module RF interface, change another matched antenna.
