Esp quick start

This is a sample project for esp-open-rtos based on esphttpd example. It contains:

• http server,
• OTA flashing via http,
• mdns server,
• wifi configuration page
• automatic switching between AP and station, depending on chosen network accessibility.

Prerequisites

This project runs with esp-open-rtos.

How to start

Before doing anything make file named local_config and in there point SDK_PATH to your sdk root e.g.:

touch local_config && echo SDK_PATH = ~/Documents/src/esp-open-rtos>local_config

Then flash with:

make flash

After flashing connect to access point named esp-open-rtos AP (password: esp-open-rtos). If there isn't such network and you configured the connection previously it's likely that esp is already connected - just skip this step.

Go to esp_test.local/. Here you can change station and AP settings.

Any subsequent flash can be made OTA (providing esp is connected to the same network as development PC):

make webflash

Webflash uses esp mdns address by default, so if your OS doesn't support mdns you have to change ESP_IP in Makefile to an actual ip address (e.g. ESP_IP ?= 192.168.0.2)

AP and station switching

At startup esp tries to connected with previously set WiFi. If this fails, it reboots and creates an access point while still trying to connect to the network. If at any point connection is successful, esp restarts, turning off the AP.
