I’m confused as to how to actually upload my certificates to the modem using AT+QFUPL.
Seen below is an image of an example in the documentation, but I don’t understand how to actually input my certificate file. What do I have to do once the terminal responds with “CONNECT”?
1、Display “connect ” information;
2、Select your CA certificate file and import it;
3、Display your CA certificate file path and file name;
4、Send and upload CA file.
I’m communicating with the BG95 with a Linux device via USB. I’ve tried the QFUPL command using both atcom and minicom. When I use atcom, it just sends a command and doesn’t prompt sending a file. I end up with CME ERROR 407.
When using minicom, after sending the QFUPL command, I get receive “CONNECT” then I go to send the file using ctrl+a z s. After about a minute, I get back
+QFUPL: 0,0
+CME ERROR: 421
Using QFLST, I can see that the file was created on the BG95 but the size is 0. I’m unsure of what I’m doing wrong or step that I’m missing.
