1. A stylus comprising:
a first sensor configured to receive a first receive signal from a touch sensor of a device;
a second sensor configured to receive a second receive signal from the touch sensor of the device; and
a controller configured to:
decode information encoded in the first receive signal and the second receive signal;
determine whether a complete header is received based at least in part on the decoded information; and
responsive to determining that a complete header is received, controls transmitting a response to the touch sensor of the device.
