however,
s uart baud 115200 is NOT valid.
Numbers can be entered as either decimal, (like 115200 above) or hex. To enter hex, use “0x” before the value: 0x<value>.
For example, the hex value FF would be entered as 0xFF.
4.2 Command Organization
Commands fall into 5 general categories:
 SET COMMANDS - Changes settings immediately and permanently (save command issued).
 GET COMMANDS - Retrieve the permanently stored information for display to user.
 STATUS COMMANDS - See what is going on with the interface, IP status, etc.
 ACTION COMMANDS - Perform action such as scan, connect, disconnect, etc.

FILE IO COMMANDS - Upgrade, load and save configuration, delete files, etc.
 NOTE: You must save any changes made or the module will load the previous settings upon reboot or power up.
When the system boots, all configuration data is loaded into RAM variables from the file called “config”. The set commands
actually only modify the RAM copy of variables in the system. In general, the IP, WLAN and UART settings need a save and
reboot to take effect, since they operate at boot up time.
For example: At power up, you will only associate, set the channel
and get your IP address once.
Most of the other commands take effect immediately like the COMM settings and timers. This allows temporary change of
parameters “on the fly” to test features, minimize power usage and save on flash re-write cycles.
Once all configuration is complete, the user must save the settings using the save command to store the configuration data,
otherwise it will not take effect upon reboot or reset. Multiple configurations can be stored by using the save <filename>
command, and these configurations can be loaded using the load <filename> command.
5 SET Commands
These commands begin with set. There are 11 major categories.
 AD-HOC - controls the ad-hoc parameters
 BROADCAST - controls the broadcast hello/heartbeat UDP message

COMM - communication and data transfer, timers, matching characters

DNS - DNS host and domain

FTP - FTP host address and login information
 IP - IP settings

OPTION - optional and not frequently used parameters

SYS - system settings such as sleep and wake timers
 TIME - timer server settings
 UART - serial port settings such as baud rate and parity

WLAN - wireless interface settings, such as SSID, channel, and security options
