IoT Modules HL78

Hello, I’m using the HL7810 module.
I want to publish an MQTT message with a JSON payload using the AT+KMQTTPUB command.
I couldn’t find any descriptions of the escape character in the AT Command Guide.
How can I escape double quotes in the payload string for AT+KMQTTPUB?

Thanks

Hi @bolt,

What firmware is HL7810 running?
Based on the description, I understand that you want to publish data that includes double quotes “”, is that what you mean?
If not, please provide a clearer description or provide the data format you want.

Thanks,
