[BC660] Check SSL connection state?

IoT Modules LPWA Module
1

Hi, I am working on firmware for the BC660.

I have successfully opened an SSL connection, sent, and received data. But I need to know the way to check the SSL connection state. For plain TCP connections, we have AT+QISTATE, and in other modules, there is the AT+QSSLSTATE, but none of them seems to work for the BC660 or are documented.

Should I assume that the connection is established until I receive an AT+QSSLURC with “closed”?

Thanks!

Yes, it is currently only through this URC return to determine whether to disconnect
