Basic Structure of Replies to AT Commands
The WSA responds to commands received with a status message and requested
actual values if necessary. The content of the response depends on the settings of
the output format (see section “Reference AT Commands”> … >“AT SYS
OUTPUT”). However, each response generally starts with a 2-digit success or
error code and ends with the console character “
>
”.
Success or error codes:
