Flash with JS Code

Hi @dlashua,

Check this page, it is nice overview of what you get with Espruino on ESP8266's.

there is no access point established by default.

Have a look at this section and use wifi.save(); to store the connection information.
The startup sequence will look for that stored information and tries to restore the wifi setup as stored (connect to AP, setup AP, or both).

flash firmware using an OTA method

Yes you can, it is implemented, check wiflash for details.
There is just one issue to fix, see #1507.

Can someone point me in the right direction?

What about get everything in place on the device and than use esptool.py to create your own v2.01_4MB file for further flash activities. Run esptool.py read_flash --help for details.
