1. A control method, comprising:
detecting first noise and determining at least one control parameter, wherein the first noise is noise affecting wireless communication between a stylus and an electronic device, and the at least one control parameter comprises a parameter controlling the wireless communication between the stylus and the electronic device;
sending first indication information to the stylus, wherein the first indication information comprises at least one parameter value, each parameter value corresponds to one of the at least one control parameter, and the first indication information is configured to adjust the at least one control parameter to the corresponding parameter value; and
controlling the wireless communication between the stylus and the electronic device in response to the adjusted control parameter;
wherein the at least one control parameter comprises both voltage and frequency, and sending the first indication information to the stylus comprises:
sending voltage indication information corresponding to the voltage and frequency indication information corresponding to the frequency to the stylus, wherein the voltage indication information comprises a voltage value corresponding to the voltage and instructs adjustment of the voltage to the voltage value; and the frequency indication information comprises a frequency value corresponding to the frequency and instructs adjustment of the frequency to the frequency value,
wherein sending the voltage indication information corresponding to the voltage and the frequency indication information corresponding to the frequency to the stylus comprises:
sending the voltage indication information to the stylus; and
in response to receiving information on successful voltage adjustment returned by the stylus and detecting second noise meeting a first condition, sending the frequency indication information to the stylus, wherein the second noise meeting the first condition comprises that a signal-to-noise ratio corresponding to the second noise is less than a preset threshold.
