I would like to configure SSL connection BG96 TLS v1.2 with PSK (pre-shared key).
There is an example in your “BG96 SSL Application Note” documentation. An example can be found in chapter 3.6.
In this example, two parameters “dtls” and “dtlsversion” are used for the AT + QSSLOPEN command, which my BG96 does not have.
In which firmware version these parameters have been added?
Firmware version of my BG96: BG96MAR02A07M1G_01.017.01.017
Where can I find the appropriate files for the upgrade?
I changed the firmware to BG96MAR03A07M1G_01.001.01.00
Now I have the dtls and dtlsversion parameters in QSSLCFG
Now I want to open an SSL connection with PSK Encryption.
I uploaded the 0_server.psk file with the necessary data.
I set up SSL context as shown in chapter 3.6 of “BG96 SSL Application Note”
I executed the AT+QSSLOPEN command, but I am not getting the +QSSLOPEN confirmation.
When I execute AT+QSSLSTATE the value of the field local_port = 0 socket_state = 1 (“Opening”)
In this state, the port remains forever.
When I execute the AT+QSSLCLOSE command, I get confirmation +QSSLOPEN with the error code 567 - “Socked has been closed”.
What do I have to do to make it work?
Why am I not receiving the +QSSLOPEN confirmation after open ?
2. After you changed to the new fw , based on the descirpition ， it seems cerification issue ，
could you test your certification with your PC first ， or send your certification to support@quectel.com ，we can test it for you ， and follow your case until it be resovled
