An active capacitive stylus configured to perform communication with a sensor controller , wherein the stylus 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 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 (CD), which does not vary depending upon an operation state of the stylus , wherein the stylus 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 (OD), which varies depending upon an operation state of the stylus , and wherein the second packet (OD_DP) does not include the configuration data (CD), wherein the stylus is further configured to acquire a local identifier (LID) included in the first request packet (CD_UP) and to set the local identifier (LID) in a communication setting table of the stylus , wherein the stylus is configured to transmit the second packet (OD_DP) including the local identifier (LID) to the sensor controller , wherein the local identifier (LID) is an identifier for uniquely identifying the stylus from among multiple styluses. wherein the stylus 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 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 (CD), which does not vary depending upon an operation state of the stylus , wherein the stylus 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 (OD), which varies depending upon an operation state of the stylus , and wherein the second packet (OD_DP) does not include the configuration data (CD), wherein the stylus is further configured to acquire a local identifier (LID) included in the first request packet (CD_UP) and to set the local identifier (LID) in a communication setting table of the stylus , wherein the stylus is configured to transmit the second packet (OD_DP) including the local identifier (LID) to the sensor controller , wherein the local identifier (LID) is an identifier for uniquely identifying the stylus from among multiple styluses. <EOS>
