BC66: AT+QSSLCFG=? failing with ERROR response

SSL related commands are responded back with ERROR from BC66 module.

  2. AT+QSSLCFG=1,5,“seclevel”,2

Software version on BC66: BC66NBR01A07

What could be the reason?

Hi Vimal
The new version can support the SSL function.
In the future, it is judged that the module does not support this function or command. After the command, =? , There is a return parameter description is supported.
