How do I compress a bin file for OTA updates

[MichaelS]

I have a development project for ESP32 using IDF ver 5.5.0 in the vscode environment and have it working including support of OTA updates. I have read online that the project.bin file can be compressed for OTA transfer using the command:

Code: Select all

idf.py gen_compressed_ota

But when I run it I get the following error.

Code: Select all

ninja: error: unknown target 'gen_compressed_ota'

Any ideas?

Any ideas?

ESP Delta OTA maybe?
Or bootloader support plus?
