When looking at the deep sleep stuff, I found there is a way to tag a global variable as ‘rtc’. That should survive a deep sleep (or reboot).
Unfortunately, it does not survive a reboot:
* Data in RTC memory is initialised whenever the SoC restarts, except when waking from deep sleep. When waking from deep sleep, the values which were present before going to sleep are kept.
There is an NVS library: https://esp-idf.readthedocs.io/en/v1.0/api/nvs_flash.html …but I've got the impression that could interfere with our own flash usage (?). Also, if flash is the way and as /store is already present at housekeeping init, I think we can just as well use our own config module… Regards, Michael -- Michael Balzer * Helkenberger Weg 9 * D-58256 Ennepetal Fon 02333 / 833 5735 * Handy 0176 / 206 989 26
