How to read and write file with M95

IoT Modules GSM Module
1

Hi,
I am using stm32 and m95 module for an IOT device. M95 does call and sms functions.
I want to write Key and Certificate file to RAM for SSL Server connection. But I didn’t understand how to command include file path.
In GSM_SSL_Application_Note_V3.3 document,
Part of 3.1. SSL Function with Certificate and Key in RAM,
this command is used first:

AT+QSECWRITE=“RAM:ca_cert.pem”,1614,100

But I use this function for AT command in my firmware:

gsm_command(“AT+QSECDEL="RAM:ca_cert.pem"\r”, 300, msg, 100, 1, “\r\nOK\r\n”, “\r\n+CME ERROR:”);

  • So how does M95 find the file path?
  • Where is ca_cert.pem?
  • Where should be it?

And another example in
GSM_FILE _AT_Commands_Manual_V1.5
5. Examples:

file atörnek

How does M95 find test2.txt file?

Please run the following command and upload the result. Preliminary judgment may be that M95 does not support SSL.

AT+QSECWRITE=?
AT+QFUPL=?
AT+QSECDEL=?

Thank you for answer.
Yes I tried this commands, M95 supports SSL and file functions.
I find the solution. I send binary data to RAM with uart as AT-command.

gsm_command("AT+QSECWRITE=\"RAM:clt.pem\",1500,100\r", 10000, msg, 100, 3, "\r\n+QSECWRITE:", "\r\nCONNECT", "\r\n+CME ERROR:");
Return file size and checksum: QSECWRITE: 1334,6e7c\r\n\r\n

gsm_command("-----BEGIN CERTIFICATE----- MIIDrDCCApQCCQDap/pt+urfQzA .....

gsm_command("AT+QSECREAD=\"RAM:clt.pem\"\r", 1000, msg, 100, 2, "\r\n+QSECREAD:", "\r\n+CME ERROR:");
Return 1 and checksum: QSECREAD: 1,6e7c

gsm_command("AT+QFLDS=\"RAM\"\r", 300, msg, 100, 1, "\r\n+QFLDS:");
Return free storage and total storage size: QFLDS: 642556,647668,642556

Configure CA certificate.
gsm_command("AT+QSSLCFG=\"cacert\",0,\"RAM:ca.pem\"\r", 1000, msg, 100, 2, "\r\nOK", "\r\nERROR"); // OK

Configure client certificate.
gsm_command("AT+QSSLCFG=\"clientcert\",0,\"RAM:clt.pem\"\r", 1000, msg, 100, 2, "\r\nOK", "\r\nERROR"); // OK

Configure client key
gsm_command("AT+QSSLCFG=\"clientkey\",0,\"RAM:key.pem\"\r", 1000, msg, 100, 2, "\r\nOK", "\r\nERROR"); // OK
