Updating sdkconfig using OTA
Posted: Wed Sep 16, 2020 7:40 pm
Hi,
I am trying to figure out if it is possible to change the sdkconfig that was flashed onto a device by using OTA. According to a comment made in another thread, recent ESP-IDF versions will reconfigure the SPI flash when the app starts after an OTA update.
However based on my tests, new sdkconfig parameters do not take effect after an OTA update. The device runs the new program, but uses the old sdkconfig.
Is there a way to update the sdkconfig without needing to re-flash the device?
