WICED SDK has two snip applications:
- apps/snip/ota_fr : This creates a webserver that a remote device can log to and upload the new version
- apps/snip/tftp: This have a TFTP application that can run as a client or server and can be used to do OTA as well.
I have WICED SDK 3.1.2. And I could not find any TFTP application. If you can share the TFTP snippet, we can use it for the OTA. Thanks for the information shared.
