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 CC2540-datasheet. 3.There is a carrier frequency interference, change the channel. 4.The antenna unmatched to the module RF interface, change another matched antenna. |
