An active capacitive stylus (100, 101, 102) configured to perform communication with a sensor controller, wherein the stylus (100, 101, 102) is configured to, if a discovery packet (D_UP) from the sensor controller is received, send a discovery response packet (D_DP) to the sensor controller, wherein the stylus is further configured to, if a channel change requests packet (CC_UP) from the sensor controller is received, acquire a second communication channel, wherein at least a portion of the communication channel is designated by the channel change request packet (CC_UP), wherein the stylus (100, 101, 102) is further configured to, in response to receiving a first request in response to receiving a first request packet (CD_UP) from the sensor controller, transmit a first packet (CD_DP) to the sensor controller, wherein the first packet (CD_DP) includes static configuration data, which does not vary depending upon an operation state of the stylus (100, 101, 102), wherein the stylus (100, 101, 102) is further configured to, in response to receiving a second request packet (OD_UP) from the sensor controller, transmit a second packet (OD_DP) to the sensor controller, wherein the second packet (OD_DP) includes operation state data, which varies depending upon an operation state of the stylus (100, 101, 102), and wherein the second packet (OD_DP) does not include the configuration data, wherein the stylus (100, 101, 102) is further configured to acquire a local identifier included in the first request packet (CD_UP) and to set the local identifier in a communication setting table of the stylus, wherein the stylus is configured to transmit the second packet (OD_DP) including the local identifier to the sensor controller, wherein the local identifier is an identifier for uniquely identifying the stylus from among multiple styluses. wherein the stylus (100, 101, 102) is configured to, if a discovery packet (D_UP) from the sensor controller is received, send a discovery response packet (D_DP) to the sensor controller, wherein the stylus is further configured to, if a channel change requests packet (CC_UP) from the sensor controller is received, acquire a second communication channel, wherein at least a portion of the communication channel is designated by the channel change request packet (CC_UP), wherein the stylus (100, 101, 102) is further configured to, in response to receiving a first request in response to receiving a first request packet (CD_UP) from the sensor controller, transmit a first packet (CD_DP) to the sensor controller, wherein the first packet (CD_DP) includes static configuration data, which does not vary depending upon an operation state of the stylus (100, 101, 102), wherein the stylus (100, 101, 102) is further configured to, in response to receiving a second request packet (OD_UP) from the sensor controller, transmit a second packet (OD_DP) to the sensor controller, wherein the second packet (OD_DP) includes operation state data, which varies depending upon an operation state of the stylus (100, 101, 102), and wherein the second packet (OD_DP) does not include the configuration data, wherein the stylus (100, 101, 102) is further configured to acquire a local identifier included in the first request packet (CD_UP) and to set the local identifier in a communication setting table of the stylus, wherein the stylus is configured to transmit the second packet (OD_DP) including the local identifier to the sensor controller, wherein the local identifier is an identifier for uniquely identifying the stylus from among multiple styluses.
