我想使用At Command在SIM800c调制解调器中上传SSL证书,并遵循与文档中所述相同的过程。但是我每次都失败了。 AT命令的过程如下:
AT+FSCREATE=C:\IOTHUB.crt<CR><LF>
OK<CR><LF>
AT+FSWRITE=C:\IOTHUB.crt,0,1188,10<CR><LF>

任何帮助都是有意义的

在David Betancourt的comment中:使用Quectel的QCom软件上载.crt
文件。
步骤:
.pem
或.crt
文件。它的大小将显示在中间文本框中,请在命令后面使用此大小。例如:
# Notice: lines with ":::" are results.
# delete the file (if it exists)
AT+FSDEL=C:\User\my.cer
::: OK
# or if not exist
::: ERROR
# create an empty file
AT+FSCREATE=C:\User\my.cer
::: OK
# open created file to write. you must set "size" properly according to your .crt file. In my case it has 1376 bytes.
###### AT+FSWRITE=<path>,<mode>,<size>,<timeout> ####
AT+FSWRITE=C:\User\my.cer,0,1376,30
::: >
`at this point click on the "send file" button`
::: OK
# to view the file
AT+FSREAD=C:\User\my.cer,0,1376,0
::: content of the file ....
# set certificate
AT+SSLSETCERT="C:\User\my.cer"
::: +SSLSETCERT: 0
这些步骤之后HTTPS是否正常工作?对于我来说,答案是否定的。 我成功导入了,但是仍然无法与某些网站建立https连接。
