I managed to prepare for myself a template for OtA updates as a base for my project.
It was working ok as far as everything was on my desk , with nodemcu board.
But after I uploaded firmware to generic ESP12 board and moved it away, OtA is just not working anymore... (main application itself is ok, but I cannot perform updates anymore).
Seems (from what I can tell from web server logs) it downloads 1st file (ROM_0_URL) but is not trying to get SPIFFS_URL, and even main app is not storing to flash.
Im not sure what can be wrong... is it my application or some settings ? (I basically followed to and extended the example from Basic_rBoot). Or ESP12 needs some HW tweaking to perform flash update itself ?
Im trying to get some advises before I dive deeper with debugging, maybe solution is simple and someone get trough it yet ?
Thanks in advance.
