Let's Control It

Hi,

I have a couple of ESP01, 8266's out on my lan, still running R120 that I'd like to upgrade to current "20111 - Mega" version of EspEasy.

I note an 'Update Firmware' warning on similar devices already running Mega: "Load a new firmware WARNING OTA not possible. Max sketch size: 599 kB (614384 bytes)". OTA likely unsupported by R120 anyways, so manual upgrade is called for.

I also note a 'Settings Load' warning on similar devices already running Mega: "Note: (File MUST be renamed to "config.dat" before upload!)" R120 seems to save as eg: 'Config_ESP1_U1_R120_2021_1_1.txt', so a file rename is in order.

Assuming I heed these two warnings , if I 'save' the settings from the tools page in R120, can I do the upgrade to "mega" manually, and then inhale the saved but renamed R120 settings file to re establish the existing config?

Is this process known to work /abandoned and vestigial, any pitfalls to be aware of, have I misunderstood completely?

Thanks,

R120 didn't have the same settings structure as far as I remember, so I don't think they are settings compatible.

Thanks.

what about OTA upgrade from Mega (builds 20000 or 20103) to latest version - does devices survive and config stays useful?

That should work. (at least that has been my intention to keep settings compatible)

I upgraded one build 20103 (ESPEasy_mega-20181231), OTA reflash was sucessfull, but afterwards I am experiencing problems that ESP node is constantly connecting/disconnecting from WIFI with reason "WIFI : Disconnected! Reason: '(200) Beacon timeout'".

Some (earlier mentioned) suggestions to try and fix this can be:
- Flash the unit via Serial (that will 'reset' some hidden Wifi settings, interfering with proper Wifi operation)
- Flash the unit with a blank.bin (of the right size) to fully clear all settings. Then flash the desired .bin (via Serial) and restore configuration from the backup you made earlier.
