This is a simple helper tool to upload a new binary to the ESP8266 over-the-air

Many projects (for example: WLED or Tasmota) provide ready to flash OTA binaries. It happens that the actual running binary is too big to do a direct OTA update.

This little sketch may solve this problem since it is small in size.

When running Tasmota: Do command SetOption78 1in Console before OTA.

Usage:

1. Manually compile or use the provided binary (folder build_output/firmware) and upload via OTA

2. Wait until upload is done. Disconnect your ESP8266 from power, wait a second and reconnect it.

3. Use a WiFi-enabled device to connect to the board's WiFi Access Point "UpdateMe". The password is "recovery".

4. In your browser, type 192.168.4.1 in the address bar. This is the module's IP.

5. You should now see a welcome screen and you are able to upload your target binary file.
