Thanks for your answer Herbert,
I don’t think the issue here are the quotation marks.
I don’t know if this topic is related to this issue I submitted on github, but I hope there is consistency between data formats in AT communication in different communication modes. In that case I found out the commands to send data through TCP and UDP didn’t require quotation marks.
However I tried to send data in multiple formats:
- hex string with and without quotation marks
- Ascii characters with and without quotation marks
- empty string ("")
I had no better results, thus I am wondering what “string of octets” means, because it is first mentioned in the device datasheet for that command in which there are no useful examples in the documentation.
I am also wondering if non ip communication may not be supported by the module I have, maybe because I have the module at the wrong version. I am thinking this because the AT commands manual of the module in question at version 1.0 (Quectel_BC95-G&BC68_AT_Commands_Manual_for_SoftBank_V1.0) says it the command is under development, while it is present at the version 1.5 (Quectel_BC95-G&BC68_AT_Commands_Manual_V1.5).
