directly operated via the built-in MCU control register and the transceiver buffer, which can complete the
receiving function of wireless data. The read-write operation timing sequence of the module register is
shown in the drawing. For more operation information, please refer to the latest data manual CC2510.

4. Frequently Asked Questions
4.1 The communications cannot be made if the module is at close range
To verify whether the sending and receiving configurations are matching and the communications
cannot be made if the configurations are different.
The voltage is abnormal; and the transmission will be abnormal if the voltage is too low.
The battery is low; and the transmission will be abnormal if the voltage is lowered due to the low
volume battery.
The RF signal does not reach the antenna or π circuit soldering occurs error if antenna welding is
abnormal.
4.2 Module communication distance is not enough
The power transmitted is small due to bad antenna impedance matching.
Objects such as metal around the antenna or the metal inside the module may cause serious signal
attenuation.
Any other interference signals in the test environment may cause the module to communicate
close.
