5. FTP Upgrade and Image Storage
Image Storage
WiFly contains a built file system for storing the firmware image(s). Files can be viewed with
the ls command. Here is an example result:
File# Size

113 Free, Boot=2, Backup=22.
Multiple files can be stored, and the boot image can be modified per below.
FTP Upload and Upgrade
WiFly contains a built in FTP client for getting files and updating the firmware. The client
uses passive mode FTP, which allows operation thru firewalls and the Internet.
There are 3 fixed settings that need to be used. The username is user. The password
is pass. The default directory is /public.
To setup FTP, the IP address of the remote server is stored using this command:
set ip ftp <addr> sets the ftp server address. .
To use FTP, enter the following command:
ftp upload <name> Retrieves remote file.
Firmware Upgrade - automatic
To use FTP to upgrade the firmware, enter the following command:
ftp upload <name> b
This will overwrite the current backup image, and updates the boot image.
Here is an example of what you should see after a successful update:
File# Size
2 12 wifly-1.05
14 1 config
15 12 wifly-1.06
101 Free, Boot=15, Backup=2.
Firmware Upgrade – manual
If it desirable to keep old images, use FTP to retrieve the file, and then use the
Set boot <sector> command to set the current boot image number.
