Special characters

I am using the BX320x WiFi - BT module successfully.
In the comunication from the CPU to the module communication I had to consider the “Special charaters” to be converted in HEX with the “\ox” format. By now the converted characters are: ‘"’ ’ ’ ‘!’ ‘#’’ ‘,’
I have a question, are there other characters we have to convert?
In the AT command Ref we can found the sentence :“Special characters (if present) appear as hex values (e.g. “\0d”)”
Were do I found an exastive list of “special chracters”?


Hi @paolo.ferretti

I have attached the ASCII table for your reference.

Hope it helps.
