Programming via Bluetooth/WiFi

[stubb0rn]

Hi

While working with my ESP I tangled myself a couple of times in cables #cablemanagement. That gave me the (not new) idea of programming the ESP wireless over BT/WiFi.
Now my question is: Has anyone seen a toolchain set-up for this? I searched a bit through google but couldn't find anything matching. I guess one could exploit the OTA feature somehow or modify the bootloader but both seems like a lot of work and any knowledge/code-reuse would pay off.
