Notes
„
You can use the command to change current / settings for a socket already opened in command
mode or in online mode after suspending it. You must set AT#SKIPESC=1.
„
To use #BASE64 in command mode, if data to send exceeds maximum value for #SSENDEXT command, you must
divide the data into multiple parts.
These parts have to be a multiple of 57 bytes, except for the last one, to distinguish EOF condition.
(Base64 encoding rules)
For the same reason if #SRECV command is used by the application to receive data, a multiple of 78 bytes has
to be considered.
„
To use #SRECV to receive data with enabled, it is necessary to consider that:
reading bytes from socket, user gets less due to decoding that is performed.
„
Values are automatically saved in non‐volatile memory.
„
Read command returns the current / settings for all the six sockets, in the format:
#BASE64:,,0,0
. . .
#BASE64:,,,0,0
Examples
AT#SKIPESC=1
OK
AT#SD=,,,
CONNECT
//Data sent without modifications. Default.
………
+++ (suspension)
OK
at#base64=,1,0
OK
AT#SO=
CONNECT
// Data received from serial port is base64 encoded before sent on the socket.
