无法使用gammu发送SMS（错误500）

Question

问题：

    pi@raspberrypi:~ $ echo "Test" | sudo gammu sendsms TEXT +937********

    If you want break, press Ctrl+C...
    Sending SMS 1/1....waiting for network answer..error 500, message reference=-1
    Unknown error.

甚至我运行脚本，它也失败了 sms.py

    import gammu
    import sys

    # Create state machine object 
    sm = gammu.StateMachine()
    # Read ~/.gammurc
    sm.ReadConfig()
    # Connect to phone
    sm.Init()

    message= {
        'Text': sys.argv[1],
        'SMSC': { 'Location': 1},
        'Number': sys.argv[2]
    }
    print(message)

    sm.SendSMS(message)
    print("Message Sent...")

输出为

    pi@raspberrypi:~ $ sudo python sms.py "Test Message" 00937********
    {'Text': 'Test Message', 'SMSC': {'Location': 1}, 'Number': '00937********'}
    Traceback (most recent call last):
        File "sms.py", line 18, in 
        sm.SendSMS(message)
    gammu.ERR_UNKNOWN: {'Text': u'Unknown error.', 'Code': 27, 'Where': 'SendSMS'}

这里如何知道我们的加密狗连接到哪个ttyUSB0/1/2

gammu——识别

    Warning: No configuration file found!
    Warning: No configuration read, using builtin defaults!
    Device: /dev/ttyUSB0
    Manufacturer: Huawei
    Model: E303 (E303)
    Firmware: 22.157.59.00.00
    IMEI: 864567010180944
    SIM IMSI: 412500242818912

gammu——调试文本AllDate——调试文件/home/pi/gammu.log标识

sudo gammu配置

gammu config命令用于设置配置，这些配置也可以在~/.gammurc文件中找到

sudo gammu——网络信息

sudo gammu getallsms

检查/dev/ttyUSB*的权限

    pi@raspberrypi:~ $ ls -l /dev/ttyUSB*
    crw-rw---- 1 root dialout 188, 0 Jan 15 12:59 /dev/ttyUSB0
    crw-rw---- 1 root dialout 188, 1 Jan 15 12:57 /dev/ttyUSB1
    crw-rw---- 1 root dialout 188, 2 Jan 15 12:57 /dev/ttyUSB2

基于以上详细信息，使用gammu的用户必须是拨号组的成员

    pi@raspberrypi:~ $ id
    uid=1000(pi) gid=1000(pi) groups=1000(pi),4(adm),20(dialout),24(cdrom),27(sudo),29(audio),44(video),46(plugdev),60(games),100(users),105(input),109(netdev),997(gpio),998(i2c),999(spi)

幸运的是，我是拨号组的成员

pi@raspberrypi:~ $ sudo usermod -a -G dialout pi

我发现了问题。这是因为wvdial配置不正确。首先确保为wvdial设置正确的配置，并将其设置为gsm文本模式

要正确配置wvdial模式，请遵循本帖子中的步骤https://stackoverflow.com/a/59697399/8403256
