RaspberryPi 4 Python使用SIM900发送彩信

Question

我正在尝试使用此代码发送彩信，但它不起作用。 我用了一些代码来发送短信，这很有效，只是彩信

APN设置很好，我检查过了。 也许添加一些输出可以帮助我解决问题，但我不知道如何以及在何处添加

我在网上搜索过，但什么也没找到

这是我的密码：

import binascii

import serial
import RPi.GPIO as GPIO      
import time
    

def img_to_hex():
    with open("/home/pi/Desktop/imagee.jpg", 'rb') as f:
        content = f.read()
        
    img_hex = binascii.hexlify(content)
    
    return img_hex
        

def send_mms():
    phone = serial.Serial("/dev/ttyS0", baudrate=9600, timeout=1)
    dataphoto = img_to_hex()

    phone.write('AT\r\n')
    time.sleep(1)

    phone.write('AT+CMMSINIT\r\n')
    time.sleep(2)

    phone.write('AT+CMMSCURL=\"mmsdebitel\"\r')
    time.sleep(1)

    phone.write('AT+CMMSCID=1\r')
    time.sleep(1)

    phone.write('AT+CMMSPROTO=\"10.143.156.003\",8080\r')

    phone.write('AT+CMMSTERM\r')
    time.sleep(1)
