Figure: OTA-FTP plugin
Firstly, there are three possibilities to be chosen:
•
Select NO_FILE to inform Waspmote that no OTA is necessary
•
Select a new file generated by the Waspmote platform IDE so as to update the Waspmote’s program.
•
Select an existing binary if the user needs to update to an older program. The files are stored in the following
path: /mnt/user/ota.
Secondly, the program version is always set by the user before generating the new UPGRADE.TXT file. There is a
specific input to indicate the program version. It must be defined as a 1-unsigned-byte number (range: from 0 to
255).
Finally, there is a button to generate the new UPGRADE.TXT file.
Once these steps have been completed, the binary file and the proper UPGRADE.TXT file will be ready for the
Waspmote devices deployed which try to perform OTA via FTP transmission. This file is shown in the window of
the application representing the actual binary prepared for OTA.
