还有还有我想问一下怎么该下面的代码不用等设备链接wifi也能运行

from pyb import UART
import json
x_threshold   = (0, 50, -24,-1, -18, 6)
led = pyb.LED(3)
usb = pyb.USB_VCP()
while(not usb.isconnected()):
	led.on()
	time.sleep_ms(150)
	led.off()
	time.sleep_ms(100)
	led.on()
	time.sleep_ms(150)
	led.off()
	time.sleep_ms(600)
	break
sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QVGA)
sensor.skip_frames(10)
sensor.skip_frames(time = 2000)
sensor.set_auto_gain(False)
sensor.set_auto_whitebal(False)
clock = time.clock()
uart = UART(3, 115200)
uart.init(115200, bits=8, parity=None, stop=1)
while(True):
	clock.tick()
	img = sensor.snapshot().lens_corr(strength = 1.6, zoom = 1.0)
	blobs = img.find_blobs([x_threshold], pixels_threshold=500, area_threshold=1550)
	if blobs:
		for b in blobs:
		    FH = bytearray([0xb3, 0xb3])
		    uart.write(FH)
		    img.draw_rectangle(b[0:4])
		    img.draw_cross(b[5], b[6])
		    print(b[5], b[6])
		    x = b.cx()
		    y = b.cy()
		    print(x, y)
		    data=bytearray([x, y, 0x1])
		    uart.write(data)
	print(clock.fps())
	print(data)
