- Mon Oct 10, 2022 11:35 am #95358 Hey,
I have an app to run a power switch, which I could update via OTA until recently.
Written in C++ against the rtos sdk.

Suddenly (after build system updates?) I find that the OTA doesn't work any more. I think I see two things : only a packet per second, and frequent timeouts. Both phenomenons are new : I used to be able to OTA my app in 30 seconds from start to reboot.

This shows some of that :

My source is at https://sourceforge.net/p/serre/svncode ... Server.cpp .

Any clues ?
Thanks,

- Tue Oct 11, 2022 11:43 am #95367 Solved by copying a file "sdkconfig.works" to the regular one.
This habit has saved my ass more than once before.

Not clear to me which of the settings below can cause this.
Some of them (number of sockets, etc) were edits from after the problem occurred.
