I am using AMW037 module in machine mode, I have been trying to find a document that presents the meaning of the response codes, e.g. R000003 when tcpc is sent. I would like a list of expected codes, not all command descriptions seem to give this information and what the error codes are.
The response format is described here:
So basically, R000003 means command successful, and the response data length is 3 bytes coming after (one bytes, the \r\n). This will be the stream handle (0, 1, etc).
