Points to Remember
Understanding of how response messages are sent to HOST MCU from GainSpan
•
Data from GainSpan can be:
–
NETWORK DATA
–
COMMAND RESPONSE
–
ASYNCRONOUS MESSAGES.
•
Data from GainSpan to S2W is not discrete. From S2W perspective, each type of data
which is to be sent to HOST MCU is a separate WRITE (on serial interface
UART/SPI/SDIO). But if HOST MCU delays in reading the data, then it can receive
multiple messages at a time. For example, it can read ASYNCHRONOUS MESSAGE
+DATA or COMMAND R DATA or 2 ASYNCHRONOUS MESSAGES.
•
HOST MCU should parse the received data in such a way that it should separate all 3
types of data (mentioned above) and process accordingly as the HOST can receive the
data which contains.

ASCII String
Meaning
1
\r\nIP2WiFi APP\r\n
Normal IP-to-WiFi adapter boot
message with internal PA.
This boot message is also applicable
when reset is triggered from external
reset pin.
2
\r\nAPP Reset External Flash
FW-UP-SUCCESS\n\r\r\n
Boot message for an adapter reset with
firmware update success
NOTE:
a.) If the asynchronous message format is enabled in the saved profile, the boot
messages are sent in the asynchronous message format.
b.) If the asynchronous message format is disabled in the saved profile, the boot
messages are sent in the format of standard responses depending on the verbose
mode.
c.) After the boot message has been received, the GS module is ready for
commands.
