Apparatus and methods of active stylus to host device data transmitting are described. One method receives, at a stylus, an indication that a host device is performing a first coordinate measurement operation to determine a coordinate of the stylus proximate to a capacitive sense array of the host device. The set of coordinate measurement operations includes a first measurement operation of a first set of electrodes of the capacitive sense array and a second measurement operation of a second set of electrodes of the capacitive sense array. While the host device is performing the set of coordinate measurement operations, the stylus transmits a data packet of stylus data to the host device. In particular, the stylus transmits a first bit of the data packet during the first measurement operation and transmits a second bit of the data packet during the second measurement operation. |
