Please note, that you now have to flash 2nd binary to a different adress 0x9000 instead of 0x40000.

Hi Necromant,

The layout in irom SDK suggested leaved a few big gaps, that were hard work with. That sucked.
Now the firmware's layout is organised in way that everything fits in the lower 256K of flash, leaving just one huge chunk of free flash before wireless config data, used by blobs. That's easier to work with and easier to understand. As side effect .irom0.text can now be extended to occupy up to ~450K (if you sacrifice OTA updates and you can ever code THAT much).

Yep. Turns out espconn_disconnect/espconn_delete can't properly terminate once a server started listening (sic!). For testing - use netcat, e.g.

Code: Select allecho hello | nc 192.168.1.234 8080


Line break terminates connection.
