openmv在IDE上可以运行，但是脱机之后为什么没反应？我程序设置了他会闪绿灯，连IDE可以正常运行，但是脱机之后灯会亮，但是openmv没反应了

我扫了一个112的二维码，然后使用bytearray转码不了，用的是uart通讯，不知道使用什么转码方式，希望能尽快解决

已解决，谢谢你的回复

报错是：uart(1) doesn't ecist

import sensor, image, time
import json
from pyb import UART
# For color tracking to work really well you should ideally be in a very, very,
# very, controlled enviroment where the lighting is constant...
yellow_threshold   = ( 46,  100,  -68,   72,   58,   92)
# You may need to tweak the above settings for tracking green things...
# Select an area in the Framebuffer to copy the color settings.

sensor.reset() # Initialize the camera sensor.
sensor.set_pixformat(sensor.RGB565) # use RGB565.

uart = UART(1,115200)

while(True):
    clock.tick() # Track elapsed milliseconds between snapshots().
    img = sensor.snapshot() # Take a picture and return the image.

    blobs = img.find_blobs([yellow_threshold])
    if blobs:
        #print('sum : %d'% len(blobs))
        data=[]
        for b in blobs:
            # Draw a rect around the blob.
            img.draw_rectangle(b.rect()) # rect
            img.draw_cross(b.cx(), b.cy()) # cx, cy
            data.append((b.cx(),b.cy()))

        #{(1,22),(-3,33),(22222,0),(9999,12),(0,0)}
        data_out = json.dumps(set(data))
        uart.write(data_out +'\n')
        print('you send:',data_out)
    else:

@kidswong999 谢谢已解决了

只打印前几个字节，怎么打印bytearray里面全部的字节啊，搞不明白呀，求大佬解答
