The description of the BG95 module only specifies 15 options as shown in the picture above.
In addition to these, I want to use Observ 6 and Block2 27, etc.
In particular, for Block2, the octet-type data format must be used, so it would be nice to see an example of writing Block2 options using AT+QCOAPOPTION.
For the format of Block2, see RFC 7959.
