1. A sewing system comprising:
a device including an image sensor; and
a sewing machine including a movement mechanism configured to hold and move an outer frame of an embroidery frame in a state in which a sewing object is clamped between the outer frame and an inner frame of the embroidery frame, the sewing machine being configured to sew an embroidery pattern on the sewing object,
the device including a processor and a memory storing computer-readable instructions that, when executed by the processor, cause the processor to perform processes comprising:
identifying, on the basis of an image when the embroidery frame is captured by the image sensor, reference point coordinates representing a position of a reference point provided in a range prescribed by the inner frame; and
transmitting, to the sewing machine, first data including the identified reference point coordinates, and
the sewing machine including a processor and a memory storing computer-readable instructions that, when executed by the processor, cause the processor to perform processes comprising:
receiving the first data transmitted by the device;
notifying a notification position, using a notification portion, with respect to the range prescribed by the inner frame of the embroidery frame held by the movement mechanism;
acquiring a relative movement amount of the embroidery frame with respect to the notification portion, for aligning the notified notification position and the position of the reference point provided in the range prescribed by the inner frame of the embroidery frame in the state of being held by the movement mechanism; and
deciding, on the basis of a relationship between the acquired movement amount and the reference point coordinates included in the first data received from the device, a deviation from a prescribed state of a positional relationship between the inner frame of the embroidery frame and the movement mechanism holding the outer frame.
